Update target_arch_elf.h to remove thread_init. Move its contents to
target_arch_thread.h and rename to target_thread_init(). Update
elfload.c to call it. Create thread_os_thread.h to hold the os specific
parts of the thread and threat manipulation routines. Currently, it just
includes target_arch_thread.h. target_arch_thread.h contains the at the
moment unused target_thread_set_upcall which will be used in the future
when creating actual thread (i386 has this stubbed, but other
architectures in the bsd-user tree have real ones). FreeBSD doesn't do
AT_HWCAP, so remove that code. Linux does, and this code came from there.
These changes are all interrelated and could be brokend down, but seem
to represent a reviewable changeset since most of the change is boiler
plate.

Recreate the FreeBSD system call numbers from current sys/syscall.h. Since this
isn't guaranteed to be on all systems, continue the practice of generating it
with some variation on:
sed -e s/SYS_/TARGET_NR_/ < $FREEBSD_SRC/sys/syscall.h > syscall_nr.h
until a more comprehensive system can be put in place.
