gyp doesn't allow two files to share the same name to avoid bugs in OS X
libtool, so asn1.c's need to all get a prefix.

RSA and ECDSA will both require being able to convert ASN.1 INTEGERs to
and from DER. Don't bother handling negative BIGNUMs for now. It doesn't
seem necessary and saves bothering with two's-complement vs
sign-and-magnitude.

Currently far from passing and I haven't even tried with a leak checker yet.
Also bn_test is slow.

Unlike the standalone build, builds generated from util/generate_build_files.py
do not exclude x86_64-gcc.c. Match the consumer builds by making the standalone
build unconditionally include it. (This would have noticed the missing
preprocessor checks in the file.)

Along the way, fix a host of missing failure checks. This will save some
headache when it comes time to run these under the malloc failure tests.

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.

(This appears to be the case with upstream too, it's not that BoringSSL
