b60007cc4e unix: add Uvmexp and SysctlUvmexp for NetBSD 
NetBSD has both struct uvmexp (used internally) and struct uvmexp_sysctl
(preferred for interfacing from user code). Expose the latter as type
Uvmexp with the same interface as on OpenBSD.

I am not sure if it makes sense to even have a name parameter for
SysctlUvmexp, since the only valid value can be "vm.uvmext2".

7c6badcd7c unix: convert openbsd/mips64 to direct libc calls 
The current code has continued to work on OpenBSD, since it has been using
syscall(2) via libc. However, the system call numbers are still hardcoded in
golang.org/x/sys/unix. Various system call changes have been made in OpenBSD,
resulting in changes to the system call numbers and arguments, which now
fail when this package is used.

Switch to calling various system calls directly via libc, rather than calling
via libc using syscall(2).

Unfortunately, this will no longer work on upstream Go since the changes
needed to convert it to libc are still blocked pending review. This means
that we're in a less than ideal situation where upstream Go openbsd/mips64
does not work on any supported OpenBSD release (in fact has not since
OpenBSD 6.8, which was EOL over a year ago), however golang.org/x/sys/unix
is now unusable with the Go package that ships with supported releases via
OpenBSD ports. It would seem that being able to actually use Go software on
a supported OpenBSD release trumps maintaining compatibility with the
unusable upstream Go source.

d9d178bc13 unix: add PthreadSigmask for Linux 
Add a syscall wrapper for SYS_RT_SIGPROCMASK and export it as
PthreadSigmask. The latter is defined by POSIX and can therefore
be implemented by Darwin, etc. later on.

Follow the approach used by Signalfd of passing _C__NSIG/8 as
sigsetsize. This avoids exporting _C__NSIG and allows the syscall
to work with the current definition of Sigset_t, which doesn't
match the kernel definition of Sigset_t.

Updates golang/go#55349
