EC_GROUP_copy is an rather unfriendly function; it doesn't work if the groups
have different[*] underlying EC_METHODs, but this notion is not exposed through
the API. I found no callers of EC_GROUP_copy in external code.
This leaves the precompute_mult functions as the remaining mutable API exposed
through EC_GROUP.
[*] Though, of the two EC_METHODs right now, simple.c is entirely unused.

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.

RC4_CHAR is a bit in the x86(-64) CPUID information that switches the
RC4 asm code from using an array of 256 uint32_t's to 256 uint8_t's. It
was originally written for the P4, where the uint8_t style was faster.
(On modern chips, setting RC4_CHAR took RC4-MD5 from 458 to 304 MB/s.
Although I wonder whether, on a server with many connections, using less
cache wouldn't be better.)
However, I'm not too worried about a slowdown of RC4 on P4 systems these
days (the last new P4 chip was released nine years ago) and I want the
code to be simplier.
Also, RC4_CHAR was set when the CPUID family was 15, but Intel actually
lists 15 as a special code meaning "also check the extended family
bits", which the asm didn't do.
The RC4_CHAR support remains in the RC4 asm code to avoid drift with
upstream.

We are leaking asm symbols in Android builds because the asm code isn't

This assumes that no asm symbols are public API and that should be true.
Some points to note:
In crypto/rc4/asm/rc4-md5-x86_64.pl there are |RC4_set_key| and
|RC4_options| functions which aren't getting marked as hidden. That's
because those functions aren't actually ever generated. (I'm just trying
to minimise drift with upstream here.)
In crypto/rc4/asm/rc4-x86_64.pl there's |RC4_options| which is "public"

deleted it. Since we have an internal caller, we'll probably have to put
it back in the future, but it can just be done in rc4.c to save
problems.

unless the target symbol is hidden then the linker doesn't know that
it's not going to be overridden by a different ELF module.
Chromium probably gets away with this because of different default

It's never called in outside code. This too seems to be a remnant of the DSA
PKIX optional parameter stuff. This is confirmed both by a removed comment and
by the brief documentation at http://www.umich.edu/~x509/ssleay/x509_pkey.html
RFC 5480 does not allow ECDSA keys to be missing parameters, so this logic is
incorrect for ECDSA anyway. It was also failing to check
EVP_PKEY_copy_parameters' return value. And that logic looks pretty suspect if
you have a chain made up multiple certificate types.

I believe this is a remnant of DSA. The logic strangely fails to check for
failure and then goes out of its way to ERR_clear_error. I believe this is so
that keys that are missing parameters silently move on. This dates to
upstream's dfeab0689f69c0b4bd3480ffd37a9cacc2f17d9c, which is SSLeay 0.9.1b. At
that time, EVP_PKEY_copy_parameters only did anything for DSA. (Now it only
does anything for ECDSA.)
My read is that this comes from DSA in PKIX's "optional domain parameters"
craziness. RFC 3279 says:
If the DSA domain parameters are omitted from the SubjectPublicKeyInfo
AlgorithmIdentifier and the CA signed the subject certificate using a
signature algorithm other than DSA, then the subject's DSA domain parameters
are distributed by other means.
This was probably part of some weird thing where, if your certificate is
missing parameters, the server would know what to use based on the private key.
(Also this was making the malloc tests unhappy.)
