All BSDs provide the SYS___GETCWD syscall which can be used to implement
Getwd.
Also add a test based on TestChdirAndGetwd from os/os_test.go

Make Madvice, Mlock, Mlockall, Mprotect, Msync, Munlock and Munlockall
available equally on all BSD flavors. NetBSD was previously lacking
SYS_MSYNC, so add it.
Reorder the //sys function prototype alphabetically and clean up already
implemented syscalls everywhere.
Also add tests for Mprotect, Msync and Madvice - now that they're
available on all unix platforms.

Follow golang.org/cl/55130 and add the utimensat syscall on *BSD. Use it
in UtimesNano and UtimesNanoAt (which is added on *BSD, akin to the
already existing implementation on Linux and Solaris).
Also add AT_FDCWD and AT_SYMLINK_NOFOLLOW where they are missing. These
might be used with UtimesNanoAt.
In order to be able to generate the syscalls, also add two missing
$GOOS_$GOARCH patterns to mkall.sh. As a side effect, some additional
syscalls are added for openbsd/arm.

Capsicum support was added by https://golang.org/cl/47290, but only for
amd64. This broke the freebsd/386 build which was subsequently fixed by
http://golang.org/cl/51270. However, even with this fix the tests still
fail to build due to the missing Capsicum functions and types.
Fix the build/test on freebsd/386 for real by re-running mkall.sh on
FreeBSD 11.1-RELEASE (inside VirtualBox) to get all the Capsicum
functions and types.
Some zerrors constants were removed or converted to enums in the FreeBSD
headers. Manually move them to a dedicated file. Do the same for amd64,
where these constants were removed by accident in
https://golang.org/cl/47290.

This avoids hanging when a Go program uses a FUSE filesystem and the
dup system call has to close a file descriptor. When dup uses
RawSyscall then the goroutine calling dup will occupy a scheduler slot
(a p structure) during the call, and may block waiting for some other
goroutine to respond to the close call on the FUSE filesystem.
Changing to Syscall avoids the problem. This makes Dup a tiny bit
slower but is quite unlikely to make a difference for any real
programs.
Update golang/go#10202.

If we use a local type, it won't compare properly with errors from
the rest of the standard library. Errors are the one type from syscall
that propagates through the system, so it's important to have only
one type for them.
Ditto for syscall.Signal.

Semi-automatic migration from package syscall to package {plan9,windows,unix}.
No builds attempted yet, but this gets a lot of noise behind us so subsequent
CLs will be more concise and easier to follow.
Subsequent CLs will have semantic content.

This CL copies to each package of go.sys the files from syscall it will need.
Different directories have different files, but these:
mkall.sh
str.go
syscall.go
mksyscall.pl
race.go
race0.go
syscall_test.go
are copied to all three.
No changes yet, these are just copies. They are not ready to use yet:
package names are wrong, for starters. But this clean copy will make
it easier to follow the changes as the packages are enabled.
