Changes between 0.9.3a and 0.9.4
*) New functions CONF_load_bio() and CONF_load_fp() to allow a config
file to be loaded from a BIO or FILE pointer. The BIO version will
for example allow memory BIOs to contain config info.
[Steve Henson]
*) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS.
Whoever hopes to achieve shared-library compatibility across versions
must use this, not the compile-time macro.
