There's a __pragma expression which allows this. Android builds us Windows with
MinGW for some reason, so we actually do have to tolerate non-MSVC-compatible
Windows compilers. (Clang for Windows is much more sensible than MinGW and
intentionally mimicks MSVC.)
MinGW doesn't understand MSVC's pragmas and warns a lot. #pragma warning is
safe to suppress, so wrap those to shush them. This also lets us do away with a
few ifdefs.

Removing the function codes continued to sample __func__ for compatibility with
ERR_print_errors_cb, but not ERR_error_string_n. We can just emit
OPENSSL_internal for both. ERR_print_errors_cb already has the file and line
number available which is strictly more information than the function name.
(ERR_error_string_n does not, but we'd already turned that to
OPENSSL_internal.)
This shaves 100kb from a release build of the bssl tool.
In doing so, put an unused function code parameter back into ERR_put_error to
align with OpenSSL. We don't need to pass an additional string in anymore, so
OpenSSL compatibility with anything which uses ERR_LIB_USER or

It's very annoying having to remember the right incant every time I want
to switch around between my build, build-release, build-asan, etc.,
output directories.
Unfortunately, this target is pretty unfriendly without CMake 3.2+ (and
Ninja 1.5+). This combination gives a USES_TERMINAL flag to
add_custom_target which uses Ninja's "console" pool, otherwise the
output buffering gets in the way. Ubuntu LTS is still on an older CMake,
so do a version check in the meantime.
CMake also has its own test mechanism (CTest), but this doesn't use it.
It seems to prefer knowing what all the tests are and then tries to do
its own output management and parallelizing and such. We already have
our own runners. all_tests.go could actually be converted tidily, but
generate_build_files.py also needs to read it, and runner.go has very
specific needs.
Naming the target ninja -C build test would be nice, but CTest squats
that name and CMake grumps when you use a reserved name, so I've gone
with run_tests.

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.
