Remove never implemented sbrk and sstk syscalls

Both system calls were stubs returning EOPNOTSUPP and libc did not
provide _ or __sys_ prefixed symbols. The actual implementation of
sbrk(2) is on top of the undocumented break(2) system call.

Technically this is a change in ABI, but no non-contrived program ever
called these syscalls.

timerfd: Move implementation from linux compat to sys/kern

Move the timerfd impelemntation from linux compat code to sys/kern. Use
it to implement the new system calls for timerfd. Add a hook to kern_tc
to allow timerfd to know when the system time has stepped. Add kqueue
support to timerfd. Adjust a few names to be less Linux centric.

freebsd32: aio_cancel takes a struct aiocb32

Strictly speaking, it takes a virtual address and doesn't touch the

fspacectl: remove unneeded freebsd32 wrapper

fspacectl(2) does not require special handling on freebsd32. The
presence of off_t in a struct does not cause it's size to change
between the native ABI and the 32-bit ABI supported by freebsd32
because off_t is always int64_t on BSD systems. Further, byte
order only requires handling for paired argument or return registers.

(32-byte alignment of 64-bit objects on i386 can require special
handling, but that situtation does not apply here.)

freebsd32: rename 32-bit compat pads to _pad

Some 32-bit architectures pass 64-bit values in aligned
register pairs (a0,a1), (a2,a3) etc. In freebsd32 we add these pads
explicitly from compat code. We also sometimes add pads in the default
ABI. Differentiate the two by making the freebsd32 ones int _pad.
In a future commit the 32-bit ones will be automatically generated.
