In FIPS mode ssleay_rand_bytes is only used for PRNG seeding and is
performed in either a single threaded context (when the PRNG is first
initialised) or under a lock (reseeding). To avoid multiple locks disable
use of CRYPTO_LOCK_RAND in FIPS mode in ssleay_rand_bytes.

Treat a NULL value passed to drbg_free_entropy callback as non-op. This
can happen if the call to fips_get_entropy fails.
Add static build support to openssl utility.
Add new "fips" option to Configure.
Make use of installed fipsld and fips_standalone_sha1
Initialise FIPS error callbacks, locking and DRBG.
Doesn't do anything much yet: no crypto is redirected to the FIPS module.
Doesn't completely build either but the openssl utility can enter FIPS mode:
which doesn't do anything much either.

Fixes to --with-zlib-include and --with-zlib-lib and init PRNG for VOS.
.DLL, in particular static build. The issue has been discussed in RT#1230
and later on openssl-dev, and mutually exclusive approaches were suggested.
This completes compromise solution suggested in RT#1230.

knock-on work than expected - they've been extracted into a patch
series that can be completed elsewhere, or in a different branch,
before merging back to HEAD.
deprecate the original (numeric-only) scheme, and replace with the
CRYPTO_THREADID object. This hides the platform-specifics and should reduce
the possibility for programming errors (where failing to explicitly check
both thread ID forms could create subtle, platform-specific bugs).
Thanks to Bodo, for invaluable review and feedback.
to 'unsigned long' (ie. odd platforms/compilers), so a pointer-typed
version was added but it required portable code to check *both* modes to
determine equality. This commit maintains the availability of both thread
ID types, but deprecates the type-specific accessor APIs that invoke the
callbacks - instead a single type-independent API is used. This simplifies
software that calls into this interface, and should also make it less
error-prone - as forgetting to call and compare *both* thread ID accessors
could have led to hard-to-debug/infrequent bugs (that might only affect
certain platforms or thread implementations). As the CHANGES note says,
there were corresponding deprecations and replacements in the
thread-related functions for BN_BLINDING and ERR too.
Note: the RAND_bytes() manual page says:
RAND_bytes() puts num cryptographically strong pseudo-random bytes into buf.
It does not talk about using the previous contents of buf so we are working
as documented.
