BN_copy can fail on malloc failure. The case in crypto/rsa was causing the
malloc tests in all_tests.go to infinite loop.

In the event of an error |rr| could be NULL. Therefore don't assume you can
use |rr| in the error handling code.

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.

Appease clang scan-build a bit. I'm not sure it's actually worth silencing all
of them because some of them look like preserving invariants between local
variables, but some are clearly pointless or can be restructured slightly.

bn_get_bits5 always reads two bytes, even when it doesn't need to. For some
sizes of |p|, this can result in reading just past the edge of the array.
Unroll the first iteration of the loop and avoid reading out of bounds.
Replace bn_get_bits5 altogether in C as it's not doing anything interesting.

It's not clear whether this inconsistency could lead to an actual
computation error, but it involved a BIGNUM being passed around the
montgomery logic in an inconsistent state. This was found using flags
-DBN_DEBUG -DBN_DEBUG_RAND, and working backwards from this assertion
in 'ectest';
