This consists of int -> ssize_t where required and one int -> mode_t.
As a rule, return types are informative rather than functional as the
actual return is in a register.

semid_t is historically an intptr_t so it should be an int32_t.

This reduces diffs when generating freebsd32 files from the default
ABI's syscalls.master.

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.

This matches the default ABI and we work around issues with
union sigval by extracting the bottom 32-bits in a manual handler.

Add freebsd32 versions of getfsstat and freebsd11_getfsstat so that
bufsize is properly sign-extended if a negative value is passed.
Reject negative values before passing to kern_getfsstat as a size_t.

Syscalls that take signed longs need to treat the 32-bit versions as
signed int so that sign extension happens correctly.  Improve
decleration quality and add a few minimal syscall implementations.

The upcoming change to generate freebsd32 generated files from
sys/kern/syscalls.master doesn't have a way to handle disabling
this one without disabling the non-COMPAT counterpart so just add
a stub for now.

Previously, the code would copy twice as many pointers as specified
and print pairs of them a single 64-bit pointer.

abort2 doesn't return so make the return type void

freebsd32_abort2 is in it's own file with a 2-clause BSD license
based on a discussion with Wojciech many years ago.

These are required when supporting i386 because time_t is 32-bit which
reduces struct bintime to 12-bytes when combined with the fact that 64-bit
integers only requiring 32-bit alignment on i386.  Reusing the default
ABI version resulted in 4-byte overreads or overwrites to userspace.

These syscalls require no translation.  They were simply missing
from compat/freebsd32/syscalls.master.
