This adds a getopt implementation for compatibility where it is not
available, removing a couple of regress patches.
Note, this is a slightly modified copy from OpenBSD libc that doesn't
expose getopt_long, which has dependency conflicts with Windows system
headers and isn't needed anyway.
This fixes nc failing to run on darwin due to it incorrectly setting the
linux-specific SOCK_NONBLOCK flag on connect.
nc already had a portability shim in apps/nc/compat/sys/socket.h, which
kicks in if SOCK_NONBLOCK is undefined. But that header includes
include/compat/sys/socket.h, which also has a portability shim that
defines a default value for SOCK_NONBLOCK if it's undefined. Thus the
first portability shim was unreachable.
Fixes this by moving the NEED_SOCKET_FLAGS flag into the outer shim, and
having the inner shim activate if NEED_SOCKET_FLAGS is defined.

The arpa/nameser.h, netinet/ip.h, and resolv.h headers are not crucial
to building LibreSSL. The netinet/ip.h header is used in nc(1) for
optional IPTOS_ features that can be ifdef'd on systems without support.
The endian.h header is the upcoming standard header and should be used
whenever available and correct. The machine/endian.h header is
non-standard and doesn't have to exist on POSIX systems.
Fix the check for getpagesize(3) not forward declaring the function,
such that CFLAGS with -Werror=implicit-function-declaration doesn't
cause the check to fail.
This takes the dynamic initialisation code added to CRYPTO_lock() in e5081719
and applies it to the Window's pthread_mutex implementation. This allows for
PTHREAD_MUTEX_INITIALIZER to be used on Windows.
bcook has agreed to place this code in the public domain (as per the rest of
the code in pthread.h).
On some targets ';' (like hppa) is treated as a comment
in assembly files. This occasionally causes the following
assembly failures:
```
Error: can't resolve `.gnu.warning.EVP_DecryptFinal'
{.gnu.warning.EVP_DecryptFinal section} - `.Ltext0' {.text section}
```
Note how branch (or other reference) attempts to cross the
boundary across two section types: '.text' and '.gnu.warning'.
Tobias Ulmer notes that openbsd already uses newlines
for similar macro:
https://github.com/openbsd/src/blob/master/sys/arch/hppa/include/cdefs.h
This change switches from ';' to newline as well.
Tested on hppa2.0 and x86_64.
