Add getrandom to FreeBSD
Introduced in FreeBSD 12.0.
Manual page: https://www.freebsd.org/cgi/man.cgi?query=getrandom.
Not sure if the constants should be `c_int`, just matching the `flags` argument in the function, in c they're macros.
Depending on the compilation environment (e.g., whether the 3XNET or
3SOCKET version of these functions is in play, whether EXTENSIONS has
been defined, etc) these functions may be declared to return either void
or int. The return value is hard coded as zero, and can be ignored to
better align with other platforms where these functions are always void.
We leave IPPROTO_MAX as is for the time being. However, in recent
kernel releases IPPROTO_MAX is actually higher and reflects the
addition of IPPROTO_MPTCP.
These syscalls were added recently, and therefore have consistent
numbers across different architetures (other than the weird offsetting
on some platforms).
Linux defines a waitid type `P_PIDFD`, for use with process file
descriptors (`pidfd`). Add that constant.
In libc-test, add linux/wait.h to the Linux-specific and
Android-specific headers, to get the definition. Exclude it on Android
and musl for now, though, as the versions in CI don't have it yet.
At time of writing, illumos systems do not provide an implementation of
the openpty() and forkpty() wrappers provided on some other UNIX
systems. While we expect to grow an implementation, it seems prudent to
provide a compatibility routine here first to unblock illumos support in
the popular nix crate.
VMADDR_CID_RESERVED is NOT available from Linux v5.6.
VMADDR_CID_LOCAL is available only on Linux >= v5.6.

Initially the EPOLLEXCLUSIVE definition was hidden on the illumos
platform as it lacked explicit support. After further review, it was
concluded that EPOLLEXCLUSIVE can safely be considered a no-op, when not
fully implemented by the OS, making it safe for use on illumos.
This adds various WASI libc definitions to the Rust libc bindings that I
needed while porting some applications to WASI.
It also removes the `pause` binding since newer versions of WASI libc
have removed this function as well. (WASI currently has no syscall with
this functionality.)
In particular:
Add timerfd constants and functions, from sys/timerfd.h.
Add EFD_SEMAPHORE and group all EFD_ constants together.
Add sigtimedwait function, from signal.h.
Add missing fallocate constants and functions, from linux/falloc.h and fcntl.h.
Add xattr functions, from sys/xattr.h.
Add SCHED_ and SEEK_ constants, from linux/sched.h and bits/seek_constants.h.
Add rlimit functions, from sys/resource.h.
Add RENAME_ constants, from stdio.h.
Add ino64_t type, from sys/types.h.
