this merges frmo trunk and fixes various build issues.
this needed a few ugly tweaks.
this hangs in "make check" now

functions called via flush_stack_call_func are assumed
to return with the global lock held again, and with
current_thread reset. this assertion verifies part of this

avoid SAFE_ALLOCA in xgselect.c.
in this code it is just as easy to always use malloc;
and it avoids thread-switching problems, as the safe-alloca
stuff implicitly refers to the current thread

this tweaks thread.c to use 'self' instead of current_thread
in a couple spots. this is clearer and more robust

initialize the saved_value field in all needed cases
also, add an assertion to do_one_unbind

unlink thread from global list later

This introduces the thread_alive_p macro and changes
thread-alive-p to use it. This is a minor cleanup.
It also changes all-threads to ignore dead threads.

This removes the call to unbind_for_thread_switch from run_thread.
This isn't necessary because acquire_global_lock does it properly.

* we called unbind_for_thread_switch unconditionally, but this
is wrong if the previous thread exited
* likewise, exiting a thread should clear current_thread
* redundant assignment in run_thread
* clean up init_threads - no need to re-init the primary thread
This patch still sometimes causes weird hangs in "make check".
However, I think that is a kernel bug, since Emacs enters the zombie
state but its parent process hangs in wait. This shouldn't happen.

Fix some process-related bugs, mostly thinkos from the conversion to
recording fd state as flags.
This now passes the test suite without hanging.

This refactors systhread.h to move the notion of a "lisp mutex"
into thread.c. This lets us make make the global lock and
post_acquire_global_lock static.

This changes wait_reading_process_output to handle threads better. It
introduces a wrapper for select that releases the global lock, and it
ensures that only a single thread can select a given file descriptor
at a time.
This also adds the thread-locking feature to processes. By default a
process can only have its output accepted by the thread that created
it. This can be changed using set-process-thread. (If the thread
exits, the process is again available for waiting by any thread.)
Note that thread-signal will not currently interrupt a thread blocked
on select. I'll fix this later.

The next step is to make it so selects can choose fds by thread.

* process.c (wait_reading_process_output): Check Writeok bits,
not write_mask.
