Add GNU-compatible strerror_r.
We already had the POSIX strerror_r, but some third-party code defines
_GNU_SOURCE and expects to get the GNU strerror_r instead.
This exposed a bug in the libc internal logging functions where unlike
their standard brethren they wouldn't return the number of bytes they'd
have liked to have written.

Slim down static binaries by avoiding stdio.
It's okay for a program to choose to drag in stdio, but it's unfortunate
if even the minimal "int main() { return 42; }" drags in stdio...
This brings the minimal static binary on ARM down from 78KiB to 46KiB.
Given that we don't have a separate -lpthread it's not obvious to me that
we can shave this down any further. I'm not sure whether this is a worthwhile
change for that reason. (And the fact that dynamic binaries, the usual case,
are unaffected either way.)

Clean up sys_signame and sys_siglist a little.
We don't need quite so much duplication because we already have a way
to get the signal number from its name, and that already copes with the
fact that the mips/mips64 numbers are different from everyone else's.
Also remove sys_signame from LP64. glibc doesn't have this BSD-ism.

Revert "Revert "More pthreads cleanup.""
This reverts commit 6f94de3ca49e4ea147b1c59e5818fa175846518f
(Doesn't try to increase the number of TLS slots; that leads to
an inability to boot. Adds more tests.)

More pthreads cleanup.
POSIX says pthread_create returns EAGAIN, not ENOMEM.
Also pull pthread_attr_t functions into their own file.
Also pull pthread_setname_np into its own file.
Also remove unnecessary #includes from pthread_key.cpp.
Also account for those pthread keys used internally by bionic,
so they don't count against the number of keys available to user
code. (They do with glibc, but glibc's limit is the much more
generous 1024.)
Also factor out the common errno-restoring idiom to reduce gotos.

glibc 2.15 treats errno as signed in strerror(3).
And the only reason I hadn't done that in bionic is because I wanted to behave
the same as glibc.

Don't copy strerror(3) or strsignal(3) strings if we can share.
