The crypto/tls and crypto/x509 APIs leak PublicKey and PrivateKey types,
so in order to add support for Ed25519 certificates we need the ed25519
package in the stdlib.
It's also a primitive that's reasonable to use directly in applications,
as it is a modern, safe and fast signing algorithm, for which there
aren't higher level APIs. (The nacl/sign API is limiting in that it
repeats the message.)
A few docs changes will come in a follow-up, and a CL will land on
golang.org/x/crypto/ed25519 to make it a type alias wrapper on Go 1.13+.

these deadlocks by retrying a missed timeout event.
A timeout event is scheduled by Go to be woken by JavaScript after a
certain amount of time. The checkTimeouts function then checks which
notes to wake by comparing their deadline to nanotime. If this
check fails erroneously then the note may stay asleep forever, causing
a deadlock. This may or may not be the reason of the observed
deadlocks.

Android tests are built on the host and run on the device. To do
that, the exec wrapper copies the test binary and testdata to the device.
To enable many more tests, make the copied environment more like the host:
- Copy all of pkg from GOROOT, not just the android pkg directory.
- Copy any parent testdata directories as well as the package's own.
- Copy *.go files from the package directory. This enables misc/cgo/stdio
and misc/cgo/life tests that were invisible before so disable them explicitly.
- Always copy the GOROOT, even for tests outside GOROOT. This is expensive
but only done once per make.bash.
- Build the go tool for the device and put it in PATH. Set GOCACHE
to a writable directory and disable cgo.
While here, use a single directory for all the exec wrapper files and
delete that once per make.bash as well.
In total, this CL enables many tests in the subrepos that would need skips
without it, in particular the x/tools tests.

Work involved in getting a stack trace is divided between
runtime.Callers and runtime.CallersFrames.
Before this CL, runtime.Callers returns a pc per runtime frame.
runtime.CallersFrames is responsible for expanding a runtime frame
into potentially multiple user frames.
After this CL, runtime.Callers returns a pc per user frame.
runtime.CallersFrames just maps those to user frame info.
Entries in the result of runtime.Callers are now pcs
of the calls (or of the inline marks), not of the instruction
just after the call.

The old code ignored the field alignment, and only looked at the field
offset: if the field offset required padding, cgo added padding. But
while that approach works for Go (at least with the gc toolchain) it
doesn't work for C code using packed structs. With a packed struct the
added padding may leave the struct at a misaligned position, and the
inserted alignment, which cgo is not considering, may introduce
additional, unexpected, padding. Padding that ignores alignment is not
a good idea when the struct is not packed, and Go structs are never
packed. So don't ignore alignment.

which is not desired if the Go program is still considered running.
This is why an explicit check on exit is used to trigger the "deadlock"
error. This CL makes it so this is Go's normal "deadlock" error, which
includes the stack traces of all goroutines.

In CLs 122575 and 123177 the cgo tool started explicitly looking up
typedefs. When there are two Go files using import "C", and the first
one has an incomplete typedef and the second one has a complete
version of the same typedef, then we will now record a version of the
first typedef which will not match the recorded version of the second
typedef, producing an "inconsistent definitions" error. Fix this by
silently merging incomplete typedefs with complete ones.

Two fixes:
1) Typedefs of the bad typedefs should also not be rewritten to the
underlying type. They shouldn't just be uintptr, though, they should
retain the C naming structure. For example, in C:
typedef const __CFString * CFStringRef;
typedef CFStringRef SecKeyAlgorithm;
we want the Go:
type _Ctype_CFStringRef uintptr
type _Ctype_SecKeyAlgorithm = _Ctype_CFStringRef
2) We need more types than just function arguments/return values.
At least we need types of global variables, so when we see a reference to:
extern const SecKeyAlgorithm kSecKeyAlgorithmECDSASignatureDigestX962SHA1;
we know that we need to investigate the type SecKeyAlgorithm.
Might as well just find every typedef and check the badness of all of them.
This requires looping until a fixed point of known types is reached.
Usually it takes just 2 iterations, sometimes 3.

We need to determine whether arguments to and return values from C
functions are "bad" typedef'd pointer types which need to be uintptr
on the Go side.
The type of those arguments are not specified explicitly. As a result,
we never look through the C declarations for the GetTypeID functions
associated with that type, and never realize that they are bad.
However, in another function in the same package there might be an
explicit reference. Then we end up with the declaration being uintptr
in one file and *struct{...} in another file. Badness ensues.
Fix this by doing a 2-pass algorithm. In the first pass, we run as
normal, but record all the argument and result types we see. In the
second pass, we include those argument types also when reading the C
types.

Before GCC 8 C code like
const unsigned long long int neg = (const unsigned long long) -1;
void f(void) { static const double x = (neg); }
would get an error "initializer element is not constant". In GCC 8 and
later it does not.
Because a value like neg, above, can not be used as a general integer
constant, this causes cgo to conclude that it is a floating point
constant. The way that cgo handles floating point values then causes
it to get the wrong value for it: 18446744073709551615 rather than -1.
These are of course the same value when converted to int64, but Go
does not permit that kind of conversion for an out-of-range constant.
This CL side-steps the problem by treating floating point constants
with integer type as they would up being treated before GCC 8: as
variables rather than constants.

to properly support timers without resorting to a busy loop.
JavaScript code can call into the same entry point multiple times.
The new RUN register is used to keep track of the program's
run state. Possible values are: starting, running, paused and exited.
If no goroutine is ready any more, the scheduler can put the
program into the "paused" state and the WebAssembly code will
stop running. When a callback occurs, the JavaScript code puts
the callback data into a queue and then calls into WebAssembly
to allow the Go code to continue running.

When using plugins with goroutines calling cgo, we hit a case where
an intermittent SIGSEGV occurs when referencing an address that is based
on r2 (TOC address). When the failure can be generated in gdb, the
contents of r2 is wrong even though the value in the current stack's
slot for r2 is correct. So that means it somehow switched to start
running the code in this function without passing through the beginning
of the function which had the correct value of r2 and stored it there.
It was noted that in runtime.gogo when the state is restored from
gobuf, r2 is not restored from its slot on the stack. Adding the
instruction to restore r2 prevents the SIGSEGV.
This adds a testcase under testplugin which reproduces the problem if
the program is run multiple times. The team who reported this problem

The iOS exec wrapper uses ios-deploy to set up a device, install
the wrapped app, and start a lldb session to run it. ios-deploy is
not built to be scripted, as can be seen from the brittle way it is
driven by the Go wrapper. There are many timeouts and comments such
as
"
// lldb tries to be clever with terminals.
// So we wrap it in script(1) and be clever
// right back at it.
"
This CL replaces the use of ios-deploy with a lldb driver script in
Python. lldb is designed to be scripted, so apart from getting rid
of the ios-deploy dependency, we gain:
- No timouts and scripting ios-deploy through stdin and parsing
stdout for responses.
- Accurate exit codes.
- Prompt exits when the wrapped binary fails for some reason. Before,
the go test timeout would kick in to fail the test.
- Support for environment variables.
- No noise in the test output. Only the test binary output is output
from the wrapper.
We have to do more work with the lldb driver: mounting the developer
image on the device, running idevicedebugserverproxy and installing
the app. Even so, the CL removes almost as many lines as it adds.
Furthermore, having the steps split up helps to tell setup errors
from runtime errors.

To enable the exec wrapper go_darwin_arm_exec.go to run binaries
on iOS devices, the GOIOS_DEV_ID variable needs to be set to a code
signing identity. The program detect.go attempts to detect suitable
values for GOIOS_DEV_ID (along with GOIOS_APP_ID and GOIOS_TEAM_ID).
Before this change, detect.go would use "security find-identity
-p codesigning -v" to list all available identities for code signing
and pick the first one with "iPhone Developer" in its name. However,
that pick might be invalid since if it was replaced by an identity
issued later.
For example, on the mobile builder:
$ security find-identity -p codesigning -v
1) 0E251DE41FE4490574E475AC320B47F58D6D3635 "lldb_codesign"
2) 0358588D07AA6A19478981BA405F40A97F95F187 "iPhone Developer: xxx@xxx (2754T98W8E)"
3) FC6D96F24A3223C98BF7A2C2C5194D82E04CD23E "iPhone Developer: xxx@xxx (2754T98W8E)"
3 valid identities found
In this case, the identity 0358588D07AA6A19478981BA405F40A97F95F187
is picked by detect.go even though it has been invalidated by
FC6D96F24A3223C98BF7A2C2C5194D82E04CD23E.
Instead of attempting to find an identity from the "security
find-identity" list, use the identity from the CommonName in the
embedded certificate in the provisioning file. The CommonName only
lists the identity name (iPhone Developer: xxx@xxx (2754T98W8E)),
not the fingerprint (FC6D96F24A3223C98BF7A2C2C5194D82E04CD23E), but
fortunately the codesign tool accepts both.
Identity names may not be unique, as demonstrated by the example,
but that will result in an ambiguity error at codesigning instead of
a more obscure error about an invalid identity when
go_darwin_arm_exec.go runs a binary.
The fix is then to delete the invalid identity from the system
keychain.
While here, find all connected devices instead of the first connected
and only consider provision files that covers them all. This matters
for the mobile builder where two devices are connected.

Once upon a time, the iOS exec wrapper needed to change the current
working directory for the binary being tested. To allow that, the
runtime raised a SIGINT signal that the wrapper caught, changed the
working directory and resumed the process.
These days, the current working directory is passed from the wrapper
to the runtime through a special entry in the app metadata and the
SIGINT handshake is not necessary anymore.
Remove the signaling from the runtime and the exec harness.
