This is similar to CL 136816 for x/sys/unix, changing the FreeBSD ABI to use 64-bit inodes in
Stat_t, Statfs_t, and Dirent types.
The changes are forward compatible, that is FreeBSD 10.x, 11.x continue to use their current sysnum numbers.
The affected types are converted to the new layout (with some overhead).
Thus the same statically linked binary should work using the native sysnums (without any conversion) on FreeBSD 12.
Breaking API changes in package syscall are:
Mknod takes a uint64 (C dev_t) instead of int.
Stat_t: Dev, Ino, Nlink, Rdev, Gen became uint64.
Atimespec, Mtimespec, Ctimespec, Birthtimespec renamed to Atim, Mtim, Ctim, Birthtim respectively.
Statfs_t: Mntonname and Mntfromname changed from [88]int8 to [1024]int8 arrays.
Dirent: Fileno became uint64, Namlen uint16 and an additional field Off int64 (currently unused) was added.
The following commands were run to generate ztypes_* and zsyscall_* on FreeBSD-12.0-ALPHA6 systems (GOARCH=386 were run on the same amd64 host):
GOOS=freebsd GOARCH=amd64 ./mksyscall.pl -tags freebsd,amd64 syscall_bsd.go syscall_freebsd.go syscall_freebsd_amd64.go |gofmt >zsyscall_freebsd_amd64.go

The Kevent struct was changed to use the FREEBSD_COMPAT11 version always (requiring the COMPAT_FREEBSD11 kernel option FreeBSD-12, this is the default).
The definitions of ifData were not updated, their functionality in has have been replaced by vendored golang.org/x/net/route.
freebsdVersion initialization was dropped from init() in favor of a sync.Once based wrapper - supportsABI().

Some syscall structures used by crypto/x509 have uintptr
fields that store pointers. These pointers are set with
a pointer to another Go structure. But the pointers are
not visible by garbage collector, and GC does not update
the fields after they were set. So when structure with
invalid uintptr pointers passed to Windows, we get
memory corruption.
This CL introduces CertInfo, CertTrustListInfo and
CertRevocationCrlInfo types. It uses pointers to new types
instead of uintptr in CertContext, CertSimpleChain and
CertRevocationInfo.
CertRevocationInfo, CertChainPolicyPara and
CertChainPolicyStatus types have uintptr field that can
be pointer to many different things (according to Windows
API). So this CL introduces Pointer type to be used for
those cases.

Variables can be declared and shadowing is supported, but modifying
existing variables via assignments was not available.
This meant that modifying a variable from a nested block was not
possible:
{{ $v := "init" }}
{{ if true }}
{{ $v := "changed" }}
{{ end }}
v: {{ $v }} {{/* "init" */}}
Introduce the "=" assignment token, such that one can now do:
{{ $v := "init" }}
{{ if true }}
{{ $v = "changed" }}
{{ end }}
v: {{ $v }} {{/* "changed" */}}
To avoid confusion, rename PipeNode.Decl to PipeNode.Vars, as the
variables may not always be declared after this change. Also change a
few other names to better reflect the added ambiguity of variables in
pipelines.
Modifying the text/template/parse package in a backwards incompatible
manner is acceptable, given that the package godoc clearly states that
it isn't intended for general use. It's the equivalent of an internal
package, back when internal packages didn't exist yet.
To make the changes to the parse package sit well with the cmd/api test,
update except.txt with the changes that we aren't worried about.

The Builder's ReadFrom method allows the underlying unsafe slice to
escape, and for callers to subsequently modify memory that had been
unsafely converted into an immutable string.
In the original proposal for Builder (#18990), I'd noted there should
be no Read methods:
> There would be no Reset or Bytes or Truncate or Read methods.
> Nothing that could mutate the []byte once it was unsafely converted
> to a string.
And in my prototype (https://golang.org/cl/37767), I handled ReadFrom
properly, but when https://golang.org/cl/74931 arrived, I missed that
it had a ReadFrom method and approved it.
Because we're so close to the Go 1.10 release, just remove the
ReadFrom method rather than think about possible fixes. It has
marginal utility in a Builder anyway.
Also, fix a separate bug that also allowed mutation of a slice's
backing array after it had been converted into a slice by disallowing
copies of the Builder by value.

When math/big was written originally, the Go compiler used 32bit
int/uint values even on a 64bit machine. uintptr was the type that
represented the machine register size. Now, the int/uint types are
sized to the native machine register size, so they are the natural
machine Word type.
On most machines, the size of int/uint correspond to the size of
uintptr. On platforms where uint and uintptr have different sizes,
this change may lead to performance differences (e.g., amd64p32).

Currently, we don't have package testing to import package regexp directly,
because then regexp can't have internal tests (or at least they become more
difficult to write), for fear of an import cycle. The solution we've been using
is for the generated test main package (pseudo-import path "testmain", package main)
to import regexp and pass in a matchString function for use by testing when
implementing the -run flags. This lets testing use regexp but without depending
on regexp and creating unnecessary cycles.
We want to add a few dependencies to runtime/pprof, notably regexp
but also compress/gzip, without causing those packages to have to work
hard to write internal tests.
Restructure the (dare I say it) dependency injection of regexp.MatchString
to be more general, and use it for the runtime/pprof functionality in addition
to the regexp functionality. The new package testing/internal/testdeps is
the root for the testing dependencies handled this way.
Code using testing.MainStart will have to change from passing in a matchString
implementation to passing in testdeps.TestDeps{}. Users of 'go test' don't do this,
but other build systems that have recreated 'go test' (for example, Blaze/Bazel)
may need to be updated. The new testdeps setup should make future updates
unnecessary, but even so we keep the comment about MainStart not being
subject to Go 1 compatibility.

of socket control message data to Cmsghdr this is only safe if the socket
control message data is greater than or equal to the size of Cmsghdr. Since
control message data that is equal in size to Cmsghdr without X__cmsg_data is
a valid socket control message, we must remove X__cmsg_data or not perform the
unsafe cast.
Removing X__cmsg_data will prevent Go code that uses X__cmsg_data from
compiling, but removing the unsafe cast will cause Go code that uses
X__cmsg_data to fail or exhibit undefined behavior at runtime. It was
therefore decided that removing X__cmsg_data was the better option.
