Rollup of errata items to be fixed before release

[noloader]

These are the issues we are aware that should be fixed prior to 5.6.3 release. They were reported after RC6 (give or take...). We are tracking them under a single bug report.

• Guard CRYPTOPP_CXX11_ALIGNOF on MSC 1900
• cryptest.exe tv all does not run HKDF tests. Need to add hkdf.txt to all.txt.
• "... to the ABI and ABI" → "... to the ABI and API" in Readme.txt.
• MinGW and error: 'memcpy_s' was not declared in this scope. Cleared with a using CryptoPP::memcpy_s;
• MinGW and rdrand detection. Investigating.
• Remove unneeded -Wno-unused-function -Wno-unused-parameter -Wno-unused-variable from GNUmakefile-cross.
• Change GNUmakefile's make docs recipe to use ref<Version> as the output directory.
• Change GNUmakefile's to avoid -fPIC for MinGW.
• Remove CRYPTOPP_DISABLE_SHA_ASM from sha.h and sha.cpp. Its an artifact from earlier testing.
• Issue 64: PolynomialMod2::operator<<= Bug - fixed the reg.Grow(...) logic
• Issue 24: Compiler warnings on GCC and MinGW - cleared the longmp warning

I don't think these two are worth a bug report of their own:

misc.h needs a s/Desitnation/Destination/g & s/satsify/satisfy/g:
misc.h#L220

• the same comment in memmove_s() @ L249.

If those are the only two you found, then I'm happy :)

My spelling and grammar is horrible at times....

Also noticed the need of s/desination/destination/g at L207, L208, L236 and L237.

I wasn't really looking for typos, it's just #28 made me spend a lot of time around memcpy_s(). :S

@Zireael-N, Have you spotted anything else that needs attention?

I'm getting ready to test RDRAND and RDSEED changes. Once they are successful, then the roll-up will be checked in.

Have you spotted anything else that needs attention?

No, I haven't.
