kernel - Fix ktrace's handling of system call return values

* Distinguish between int and long returns, properly recording
long returns (e.g. lseek(), mmap(), read(), write(), etc).
kdump will then display the correct return value instead of a truncated
return value for the affected system calls.

* Involves including a return value type width in the sysent and adjusting
the generator to calculate it.

kernel - Refactor in-kernel system call API to remove bcopy()

* Change the in-kernel system call prototype to take the
system call arguments as a separate pointer, and make the
contents read-only.

int sy_call_t (void *);
int sy_call_t (struct sysmsg *sysmsg, const void *);

* System calls with 6 arguments or less no longer need to copy
the arguments from the trapframe to a holding structure. Instead,
we simply point into the trapframe.

The L1 cache footprint will be a bit smaller, but in simple tests
the results are not noticably faster... maybe 1ns or so
(roughly 1%).

Add <sys/cpumask.h>.

Collect and gather all scatter cpumask bits to correct headers. This
cleans up the namespace and simplifies platform handling in asm macros.
The cpumask_t together with its macros is already non MI feature that is
used in userland utilities, libraries, kernel scheduler and syscalls.
It deserves sys/ header. Adjust syscalls.master and rerun sysent.

While there, fix an issue in ports that set POSIX env, but has
implementation of setting thread names through pthread_set_name_np().

Remove the <sys/syscall-hide.h> header file.

Nothing includes it, nor are the HIDE_BSD() and HIDE_POSIX() macros
actually defined anywhere.

Also, remove support for the associated POSIX, BSD and NOHIDE keywords
from the syscalls.master files. It makes the patch quite large due to
touching most lines in the syscalls.master files but it results in
zero changes in the generated files.
