Previously, gcm.c contained a lot of workarounds for cases where BSWAP8
wasn't defined. Rather than handle this in each place, just make it
always available.
While we're here, make these macros inline functions instead and rename
them to something less likely to collide.

gcm_test.cc needs to access the internal GCM symbols. This is
unfortunate because it means that they have to be marked OPENSSL_EXPORT
just for this.
To compensate, modes.h is removed and its contents copied into
crypto/modes/internal.h.

With NO_ASM defined, the recent AEAD changes broke the tests. The
problem is that the generic CBC mode code tests whether in != out and
omits to save the IV, assuming that it'll be able to read the old
ciphertext block.
However, consider the case where out = in - 16:
1 2 3 4
|-------|-------|------|-------|
^ ^
| |
out in
First time around, 1 = decrypt(2) ^ iv and everything is fine, because
the IV was preconfigured. However, the next iteration of the loop sets
2 = decrypt(3) and tries to XOR it with the contents of the previous
ciphertext block… from 2.

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.
