4b1d654efb Port libc_r to ia64. We need to do things slightly different 
because we have 2 stacks per thread: the regular downward
memory stack and the irregular upward register stack. This
implementation lets both stacks grow toward each other. An
alternative scheme is to have them grow away from each other.
The alternate scheme has the advantage that both stack grow
toward guard pages. Since libc_r is virtually dead and we
really want the *context stuff for thread switching, we don't
try to be perfect, just functional.

f8739dd5f9 Implement the lock with a cmpxchg instruction instead of a xchg. 
Both are atomic, but the cmpxchg has memory ordering hints. We
give this acquire semantics.

NOTE: The unlock in libc_r is implemented by a "normal" assign
statement. This is not correct on ia64 due to the memory ordering
characteristics of the architecture. We need release semantics
for an unlock.

e46cac58cd When about to do an execve(), don't reset the O_NONBLOCK flag on any file 
descriptors that have the close-on-exec flag set, as that will have no
effect anyway and might screw something else up if the file descriptor
happens to be shared with another process.

f38fac1471 At initialization, override the pthread stub routines in libc 
by filling in the jump table.

Convert uses of pthread routines within libc_r to use the internal
versions (_pthread_foo instead of pthread_foo).

Remove a couple of globals from application namespace.

4aba47f7ce FD locking is not enabled anymore, so the table which contains the owner 
of a file descriptor has NULL entries, so don't dereference the table entries
to get the owners ever -- don't print the owners when processing a thread_dump
request as a result of SIGINFO.

be779e1ae2 Once again, remove the i386-specific hacks to save and restore 
the FPU state on receiving and returning from a signal.
The FPU save and restore macros are no longer needed, but
remain defined in case we need to use them again (something
else breaks).  They'll be removed permanently once new
syscalls are added to handle the new i386 ucontext size.
