Beyond generally eliminating unnecessary includes, eliminate as many
includes of headers that declare/define particularly error-prone
functionality like strlen, malloc, and free. crypto/err/internal.h was
added to remove the dependency on openssl/thread.h from the public
openssl/err.h header. The include of <stdlib.h> in openssl/mem.h was
retained since it defines OPENSSL_malloc and friends as macros around
the stdlib.h functions. The public x509.h, x509v3.h, and ssl.h headers
were not changed in order to minimize breakage of source compatibility
with external code.

This involves more synchronization with child exits as the kernel no longer
closes the pre-created pipes for free, but it works on Windows. As long as
TCP_NODELAY is set, the performance seems comparable. Though it does involve
dealing with graceful socket shutdown. I couldn't get that to work on Windows
without draining the socket; not even SO_LINGER worked. Current (untested)
theory is that Windows refuses to gracefully shutdown a socket if the peer
sends data after we've stopped reading.
cmd.ExtraFiles doesn't work on Windows; it doesn't use fds natively, so you
can't pass fds 4 and 5. (stdin/stdout/stderr are special slots in
CreateProcess.) We can instead use the syscall module directly and mark handles
as inheritable (and then pass the numerical values out-of-band), but that
requires synchronizing all of our shim.Start() calls and assuming no other
thread is spawning a process.
PROC_THREAD_ATTRIBUTE_HANDLE_LIST fixes threading problems, but requires
wrapping more syscalls. exec.Cmd also doesn't let us launch the process
ourselves. Plus it still requires every handle in the list be marked
inheritable, so it doesn't help if some other thread is launching a process
with bInheritHandles TRUE but NOT using PROC_THREAD_ATTRIBUTE_HANDLE_LIST.
(Like Go, though we can take syscall.ForkLock there.)

The more natively Windows option seems to be named pipes, but that too requires
wrapping more system calls. (To be fair, that isn't too painful.) They also
involve a listening server, so we'd still have to synchronize with shim.Wait()
a la net.TCPListener.
Then there's DuplicateHandle, but then we need an out-of-band signal.
All in all, one cross-platform implementation with a TCP sockets seems
simplest.

Previously, error strings were kept in arrays for each subdirectory and
err.c would iterate over them all and insert them at init time to a hash
table.
This means that, even if you have a shared library and lots of processes
using that, each process has ~30KB of private memory from building that
hash table.
This this change, all the error strings are built into a sorted list and
are thus static data. This means that processes can share the error
information and it actually saves binary space because of all the
pointer overhead in the old scheme. Also it saves the time taken
building the hash table at startup.
This removes support for externally-supplied error string data.

Including string.h in base.h causes any file that includes a BoringSSL
header to include string.h. Generally this wouldn't be a problem,
although string.h might slow down the compile if it wasn't otherwise
needed. However, it also causes problems for ipsec-tools in Android
because OpenSSL didn't have this behaviour.
This change removes string.h from base.h and, instead, adds it to each
.c file that requires it.
