Tobias Klauser 90f0fdc418 plan9: add arm support
Copy zsyscall_plan9_arm.go from syscall and add asm_plan9_arm.s which
just contains jumps to the corresponding syscall functions.

Tobias Klauser fff93fa7cd unix: add Statx on Linux
statx(2) allows to get enhanced file status information (not currently
available through the existing stat syscalls), lightweight stat,
heavyweight stat. The Statx_t type used by Statx has consistent field
sizes on all arches (with year-2038-capable timestamps) and is closer to
the BSD implementation of Stat_t.

See http://man7.org/linux/man-pages/man2/statx.2.html for details. The
syscall was added in Linux kernel 4.11.

See https://github.com/tklauser/statx for an example of how this
function and types can be used to report stat(1)-like file status
information.

The logic in NsecToTimespec and NsecToTimeval caused times before 1970

Follow CL 70590 which did the same for syscall.

unix.Select uses SYS_PSELECT6 on arm64 and mipx64x, however this
syscall expects its 5th argument to be of type Timespec (with seconds
and nanoseconds) instead of type Timeval (with seconds and microseconds)
This leads to the timeout being too short by a factor of 1000.

This CL fixes this by adjusting the timeout argument accordingly,
similarly to how glibc does it for architectures where neither
SYS_SELECT nor SYS__NEWSELECT are available. It also makes Pselect
generaly available on linux.

Daniel Swarbrick reports the following go vet warning after CL 50550:

  .../dev_linux.go:38: (major & 0xfffff000) (32 bits) too small for shift of 32

Fix it by converting major and minor to uint64 before the bitwise-and.

Tobias Klauser a5054c7c13 unix: add Major, Minor and Mkdev functions on FreeBSD
Add Major, Minor and Mkdev functions for converting devices numbers to
their major/minor components and vice versa.

The functions follow the behavior of the macros defined in FreeBSD's
sys/types.h header. However, the parameter and return types are changed
to match the existing implementations of these functions.

Because FreeBSD dynamically allocates major/minor device numbers through
devfs at runtime, testing the conversion macros against well-known
device numbers is not possible.

Tobias Klauser 0f826bdd13 unix: re-enable Capsicum on FreeBSD 386
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.
