964ed94649 parisc-mont.pl: PA-RISC 2.0 code path optimization based on intruction- 
level profiling data resulted in almost 50% performance improvement.
PA-RISC 1.1 is also reordered in same manner, mostly to be consistent,
as no gain was observed, not on PA-7100LC.

impressive as with complete assembler, but still... it's almost 2.5x

4c3296960d Remove the dual-callback scheme for numeric and pointer thread IDs, 
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.

830b8877ba Takanori Yanagisawa has shown how to correctly use pre-computed values. 
So in a sense this commit reverts few latest ones fixing bugs in original
code and improving it, most notably adding 64-bit support [though not in
BN_nist_mod_224 yet].

f7ccba3edf There was a need to support thread ID types that couldn't be reliably cast 
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.
