There seem to be no way to simply clear the app data for an app

This change in effect undoes CL 106676, which means that running iOS

apple developer account must be present on the device for our app
install to succeed.

This commit adds the syscall/js package, which is used by the wasm
architecture to access the WebAssembly host environment (and the
operating system through it). Currently, web browsers and Node.js
are supported hosts, which is why the API is based on JavaScript APIs.
There is no common API standardized in the WebAssembly ecosystem yet.
This package is experimental. Its current scope is only to allow
tests to run, but not yet to provide a comprehensive API for users.

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.

Both gcc and clang accept an option -fplugin=code.so to load
a plugin from the ELF shared object file code.so.
Obviously that plugin can then do anything it wants
during the build. This is contrary to the goal of "go get"
never running untrusted code during the build.
(What happens if you choose to run the result of
the build is your responsibility.)
Disallow this behavior by only allowing a small set of
known command-line flags in #cgo CFLAGS directives
(and #cgo LDFLAGS, etc).
The new restrictions can be adjusted by the environment
variables CGO_CFLAGS_ALLOW, CGO_CFLAGS_DISALLOW,
and so on. See the documentation.
In addition to excluding cgo-defined flags, we also have to
make sure that when we pass file names on the command
line, they don't look like flags. So we now refuse to build
packages containing suspicious file names like -x.go.
A wrinkle in all this is that GNU binutils uniformly accept
@foo on the command line to mean "if the file foo exists,
then substitute its contents for @foo in the command line".
So we must also reject @x.go, flags and flag arguments
beginning with @, and so on.

Fixed by CL 76025 yesterday, without realizing it:
the testshared and testplugin builds of separate iface_i
packages were colliding incorrectly in the cache.
Including the build directory fixes that.
Fixes#22571.

The iOS test harness dumps the output of its lldb session to stdout,
but only if the lldb session was successfully started.
Make sure the log is always dumpede, so that lldb startup failures
such as
lldb setup error: exited (lldb start: exit status 253)
can be diagnosed.
For the iOS builders.

This reverts commit 08f19bbde1.
Reason for revert:
The changed transformation takes effect on a larger set
of code snippets than expected.
For example, this:
func foo() {
// Comment
bar()
}
becomes:
func foo() {
// Comment
bar()
}
This is an unintended consequence.

Some C types are declared as pointers, but C code
stores non-pointers in them. When the Go garbage
collector sees such a pointer, it gets unhappy.
Instead, for these types represent them on the Go
side with uintptr.
We need this change to handle Apple's CoreFoundation
CF*Ref types. Users of these types might need to
update their code like we do in root_cgo_darwin.go.
The only change that is required under normal
circumstances is converting some nils to 0.
A go fix module is provided to help.
Fixes#21897
