Add automatic threading initialization for libcrypto.

This implements automatic thread support initialization in libcrypto.
This does not remove any functions from the ABI, but does turn them into
no-ops. Stub implementations of pthread_mutex_(init|lock|unlock) are
provided for ramdisks.

This does not implement the new OpenSSL 1.1 thread API internally,
keeping the original CRYTPO_lock / CRYPTO_add_lock functions for library
locking. For -portable, crypto_lock.c can be reimplemented with
OS-specific primitives as needed.

Use a Thread Information Block in both single and multi-threaded programs.
This stores errno, the cancelation flags, and related bits for each thread
and is allocated by ld.so or libc.a. This is an ABI break from 5.9-stable!

Make libpthread dlopen'able by moving the cancelation wrappers into libc
and doing locking and fork/errno handling via callbacks that libpthread
registers when it first initializes. 'errno' *must* be declared via
<errno.h> now!

Clean up libpthread's symbol exports like libc.

On powerpc, offset the TIB/TCB/TLS data from the register per the ELF spec.

Blargh: unbreak after libc/Makefile.inc change

add -I${LIBCSRCDIR}/hidden to handle _glibc_ churn

use NOMAN=1 for all directories

rename SHA256_ONLY to SHA2_SMALL; changing things so that sha512 support
is also pulled in

oops, meant MACHINE_CPU not MACHINE_ARCH (matters for mips64*)

Provide -I's to reach the gdtoa directory for .h files

switch to the new resolver implementation.

Add support for C99 %ls, %lc, and %l[ format directives to scanf(3).
Based on code from FreeBSD.

Fix fallout from the utf-8 commit (segfaults in disklabel on install media).

Replace the single-byte placeholders for the multi-byte/wide-character
conversion interfaces of libc (mbrtowc(3) and friends) with new
implementations that internally call an API based on NetBSD's ci

Replace the single-byte placeholders for the multi-byte/wide-character
conversion interfaces of libc (mbrtowc(3) and friends) with new
implementations that internally call an API based on NetBSD's citrus.
This allows us to support locales with multi-byte character encodings.

Provide two implementations of the citrus-based API: one based on the old
single-byte placeholders for use with our existing single-byte character
locales (C, ISO8859-*, KOI8, CP1251, etc.), and one that provides support
for UTF-8 encoded characters (code based on FreeBSD's implementation).

Install the en_US.UTF-8 ctype locale support file, and allow the UTF-8
ctype locale to be enabled via setlocale(3) (export LC_CTYPE='en_US.UTF-8').

A lot of programs, especially from ports, will now start using UTF-8 if the
UTF-8 locale is enabled. Use at your own risk, and please report any breakage.
Note that ncurses-based programs cannot display UTF-8 right now, this is being
worked on.

To prevent install media growth, add vfprintf(3) and mbrtowc(3) to libstubs.
The mbrtowc stub was copied unchanged from its old single-byte placeholder.
vfprintf.c doesn't need to be copied, just put in .PATH (hint by fgsch@).

More shrinkage, a bit for ramdisks but mostly for static binaries:
- wrap with #ifndef NO_LOG_BAD_DNS_RESPONSES libc code that uses
p_class() and p_type() for diagnostics, then add that define to
libstub to avoid pulling in res_debug_syms.o
- split rcmd() and ruserok() into separate files, as nothing uses both
- split readdir_r() to its own file
- split syslog_r() from syslog(), as the latter needs localtime(); many
binaries no longer need to pull in all the time code after this; switch
from usleep() to nanosleep() while we're at it

Pull sha2.c from libc into libstubs, but compile it with -DSHA256_ONLY
