c8d2fd6da8 Update libc dns code to 4.9.7-T1B level. This involved chopping out large 
chunks of res_comp.c and replacing it with chunks of bind-8.1.1's resolver
code.  (There are no interface changes though)
The other parts are better bounds checking related.

9b7c9bc4f8 Oops, backout the previous change having confused my underscores. 
__thread_create is a syscall that uses the default asm. It is
_thread_create that contains specific asm code, but that lives in
libpthread.

3fece7a1aa Make cerror thread aware by calling __error() to get a pointer to the 
thread-specific error variable. This change make libc use the same cerror
code that libc_r has been using.

68f87034f2 The syscall that creates a kernel thread is coming, but it doesn't use the 
default syscall asm, so add it to NOASM. The other syscalls that manipulate
kernel threads use the default asm code, so they just get built
automatically.

cf6229a854 Build __error.c into libc, but not libc_r. The weak symbol in the 
file works with libpthread, but when built into libc_r which has a non-weak
symbol of the same name, the linker behaves unpredicatably and sometimes
links the wrong symbol. The linker behaviour is a byproduct of what
the program calls from object to object so it is like winning a lottery
if the program actually works. The odds are quite good - 95:1, I think.
We need a sure thing, though, so weak symbols can't be used instead
of renaming things.

7bb870ac66 Change the name of this source file so that libc_r builds it instead 
of the one in libc that contains the weak symbol for __error. FreeBSD's
make accumulates paths to the point that it can find *anything*, possibly
including the car keys.

4a027d50c7 Change signal model to match POSIX (i.e. one set of signal handlers 
for the process, not a separate set for each thread). By default, the
process now only has signal handlers installed for SIGVTALRM, SIGINFO
and SIGCHLD. The thread kernel signal handler is installed for other
signals on demand. This means that SIG_IGN and SIG_DFL processing is now
left to the kernel, not the thread kernel.

Change the signal dispatch to no longer use a signal thread, and
call the signal handler using the stack of the thread that has the
signal pending.

Change the atomic lock method to use test-and-set asm code with
a yield if blocked. This introduces separate locks for each type
of object instead of blocking signals to prevent a context
switch. It was this blocking of signals that caused the performance
degradation the people have noted.

This is a *big* change!

b37727fff9 sigprocmask()' man page references sigmask()' in synopsis. 
Note odd `sigmask()' line in synopsis.  `sigsetops(3)' is better suited
for `sigprocmask' and is already referenced from the manual page.
(`sigmask()' is useful for the older (& deprecated) `sigsetmask()' API).
