0bbb587407 Add atoll(3) to libnbcompat. We need it when building target's gcc
for a 64-bit target on a 32-bit host.

NB: There seems to be a bug in either gcc itself or the way we import
it, b/c the incorrect #define HAVE_ATOLL is picked from (e.g. for
sparc64) gnu/usr.bin/gcc/arch/sparc64/auto-host.h - so when gen*
auxilary (host) programs are built in gnu/usr.bin/gcc/backend, they
incorrectly pick-up target's HAVE_ATOLL.

For now providing atoll(3) in libnbcompat is a simple and sufficient
workaround.

aa70f03b23 When implementing a recursive mutex, it helps if you remember to
decrement the recursion count.

Fixes the problem of uic dying with a no-next-thread assertion while
building kdeadmin3; reported by Perry Metzger and others on

f60f35f3ab Don't acquire __environ_lock around exec*() calls; nothing requires
that these calls be thread-safe with respect to the environment, and it
causes serious problems for threaded applications which call vfork() and
exec*() (including indirectly, via popen() or system()).

Acquire and release __environ_lock in the parent in popen() and system() to
play safe and provide the child with a stable environment.

__environ_lock should also have an atfork() handler; still under development.

65ec6ba6e7 Fix lib/20558:
A dynamically linked program invokes the rtld cleanup routine via
an atexit handler.  This rtld cleanup routine invokes _fini() for
shared libraries, which in-turn invoke __cxa_finalize() with their
DSO handle.  By luck, this happens to work okay for non-threaded
programs, but for a threaded program, this leads to deadlock (sometimes
manifested as an assertion failure, if the program didn't actually
create any threads).

Fixed by teaching __cxa_finalize() that it can be recursively invoked,
adjusting the handler list manipulation accordingly.

b2126f94bb More fixes:
1. use uintptr_t instead of u_long
2. check for overflow in map_pages and malloc_pages
3. bring in fixes from FreeBSD [int -> size_t, and a missing THREAD_UNLOCK]
4. rewrite map_pages to use sbrk() only to grow memory (avoids extra syscall
   and elides bug in brk(2) that ross is fixing)
5. restore the break point to its original value if the mmap(2) for the page
   directory or the alignment sbrk breaks.

reviewed by: chuq and ross
tested by: make build and reboot
Now memtest nearly works; unfortunately there is no way currently to lower
the break point as we free, so memtest keeps trying to reduce memory when
mlock() fails and that does not work.
