Make all configuration macros available for application by making sure they are available in opensslconf.h, by giving them names starting with "OPENSSL_" to avoid conflicts with other packages and by making sure e_os2.h will cover all platform-specific cases together with opensslconf.h. I've checked fairly well that nothing breaks with this (apart from external software that will adapt if they have used something like NO_KRB5), but I can't guarantee it completely, so a review of this change would be a good thing.

Fix reseeding issues of the public RAND_DRBG Reseeding is handled very differently by the classic RAND_METHOD API and the new RAND_DRBG api. These differences led to some problems when the new RAND_DRBG was made the default OpenSSL RNG. In particular, RAND_add() did not work as expected anymore. These issues are discussed on the thread '[openssl-dev] Plea for a new public OpenSSL RNG API' and in Pull Request #4328. This commit fixes the mentioned issues, introducing the following changes: - Replace the fixed size RAND_BYTES_BUFFER by a new RAND_POOL API which facilitates collecting entropy by the get_entropy() callback. - Don't use RAND_poll()/RAND_add() for collecting entropy from the get_entropy() callback anymore. Instead, replace RAND_poll() by RAND_POOL_acquire_entropy(). - Add a new function rand_drbg_restart() which tries to get the DRBG in an instantiated state by all means, regardless of the current state (uninstantiated, error, ...) the DRBG is in. If the caller provides entropy or additional input, it will be used for reseeding. - Restore the original documented behaviour of RAND_add() and RAND_poll() (namely to reseed the DRBG immediately) by a new implementation based on rand_drbg_restart(). - Add automatic error recovery from temporary failures of the entropy source to RAND_DRBG_generate() using the rand_drbg_restart() function.

crypto/rand: restore the generic DRBG implementation The DRGB concept described in NIST SP 800-90A provides for having different algorithms to generate random output. In fact, the FIPS object module used to implement three of them, CTR DRBG, HASH DRBG and HMAC DRBG. When the FIPS code was ported to master in #4019, two of the three algorithms were dropped, and together with those the entire code that made RAND_DRBG generic was removed, since only one concrete implementation was left. This commit restores the original generic implementation of the DRBG, making it possible again to add additional implementations using different algorithms (like RAND_DRBG_CHACHA20) in the future.

crypto/rand: restore the generic DRBG implementation The DRGB concept described in NIST SP 800-90A provides for having different algorithms to generate random output. In fact, the FIPS object module used to implement three of them, CTR DRBG, HASH DRBG and HMAC DRBG. When the FIPS code was ported to master in #4019, two of the three algorithms were dropped, and together with those the entire code that made RAND_DRBG generic was removed, since only one concrete implementation was left. This commit restores the original generic implementation of the DRBG, making it possible again to add additional implementations using different algorithms (like RAND_DRBG_CHACHA20) in the future.

Fix reseeding issues of the public RAND_DRBG Reseeding is handled very differently by the classic RAND_METHOD API and the new RAND_DRBG api. These differences led to some problems when the new RAND_DRBG was made the default OpenSSL RNG. In particular, RAND_add() did not work as expected anymore. These issues are discussed on the thread '[openssl-dev] Plea for a new public OpenSSL RNG API' and in Pull Request #4328. This commit fixes the mentioned issues, introducing the following changes: - Replace the fixed size RAND_BYTES_BUFFER by a new RAND_POOL API which facilitates collecting entropy by the get_entropy() callback. - Don't use RAND_poll()/RAND_add() for collecting entropy from the get_entropy() callback anymore. Instead, replace RAND_poll() by RAND_POOL_acquire_entropy(). - Add a new function rand_drbg_restart() which tries to get the DRBG in an instantiated state by all means, regardless of the current state (uninstantiated, error, ...) the DRBG is in. If the caller provides entropy or additional input, it will be used for reseeding. - Restore the original documented behaviour of RAND_add() and RAND_poll() (namely to reseed the DRBG immediately) by a new implementation based on rand_drbg_restart(). - Add automatic error recovery from temporary failures of the entropy source to RAND_DRBG_generate() using the rand_drbg_restart() function.

Precautions against using the PRNG uninitialized: RAND_bytes() now returns int (1 = ok, 0 = not seeded). New function RAND_add() is the same as RAND_seed() but takes an estimate of the entropy as an additional argument.
