Last modification effectively masked test failures, so that builds
were reported successful even if they failed.

When configured no-engine, we still refered to rand_engine_lock.
Rework the lock init code to avoid that.

The old custom extensions API was not TLSv1.3 aware. Extensions are used
extensively in TLSv1.3 and they can appear in many different types of
messages. Therefore we need a new API to be able to cope with that.

This move prepares for the later addition of the new custom extensions
API. The context codes have an additional "SSL_" added to their name to
ensure we don't have name clashes with other applications.

This is especially harmful since OPENSSL_cleanup() has already called

Under UEFI build environment, we may encounter the OSSL_SSIZE macro
re-definition error in e_os2.h if any module call OpenSSL API directly
by including "openssl/xxxx.h" (caused by the predefined _WIN32/_WIN64
macro, which should have been un-defined under OPENSSL_SYS_UEFI).

Though it's not one recommended usage, this patch could still eliminate
the possible build issue by refining the OSSL_SSIZE definition under
OPENSSL_SYS_UEFI.

If no default method was yet given, RAND_get_rand_method() will set it
up.  Doing so just to clean it away seems pretty silly, so instead,
use the default_RAND_meth variable directly.

This also clears a possible race condition where this will try to init
things, such as ERR or ENGINE when in the middle of a OPENSSL_cleanup.

This commit contains some optimizations in PKCS5_PBKDF2_HMAC() and
HMAC_CTX_copy() functions which together makes PBKDF2 computations
faster by 15-40% according to my measurements made on x64 Linux with
both asm optimized and no-asm versions of SHA1, SHA256 and SHA512.

This increases portability of SSL_SESSION files between architectures
where the size of |long| may vary.  Before this, SSL_SESSION files
produced on a 64-bit long architecture may break on a 32-bit long
architecture.
