All supported BSDs provide the SYS___GETCWD syscall which can be used to
implement syscall.Getwd. With this change os.Getwd can use a single
syscall instead of falling back to the current kludge solution on the
BSDs.
This doesn't add any new exported functions to the frozen syscall
package, only ImplementsGetwd changes to true for dragonfly, freebsd,
netbsd and openbsd.
As suggested by Ian, this follows CL 83755 which did the same for
golang.org/x/sys/unix.
Also, an entry for netbsd/arm is added to mkall.sh which was used to
generate the syscall wrappers there.

Increase MaxBase from 36 to 62 and extend the conversion
alphabet with the upper-case letters 'A' to 'Z'. For int
conversions with bases <= 36, the letters 'A' to 'Z' have
the same values (10 to 35) as the corresponding lower-case
letters. For conversion bases > 36 up to 62, the upper-case
letters have the values 36 to 61.
Added MaxBase to api/except.txt: Clients should not make
assumptions about the value of MaxBase being constant.
The core of the change is in natconv.go. The remaining
changes are adjusted tests and documentation.
Fixes#21558.

For compatibility with math/bits uint operations.
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).

Change the openbsd runtime to use the current sys_kill and sys_thrkill
system calls.
Prior to OpenBSD 5.9 the sys_kill system call could be used with both
processes and threads. In OpenBSD 5.9 this functionality was split into
a sys_kill system call for processes (with a new syscall number) and a
sys_thrkill system call for threads. The original/legacy system call was
retained in OpenBSD 5.9 and OpenBSD 6.0, however has been removed and
will not exist in the upcoming OpenBSD 6.1 release.
Note: This change is needed to make Go work on OpenBSD 6.1 (to be
released in May 2017) and should be included in the Go 1.8 release.
This change also drops support for OpenBSD 5.8, which is already an
unsupported OpenBSD release.

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.

This field is a zero length array and has little use. Since Go 1.5, trailing
zero-length arrays take up space. Both syscall.UnixRights() and
syscall.ParseSocketControlMessage() depend on being able to do an unsafe cast
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.
