8c3bc594e0 Processing GNU-style "make variables" - separate CPP flags from C flags
C preprocessor flags get separated from C flags, which has the
advantage that we don't get loads of macro definitions and inclusion
directory specs when linking shared libraries, DSOs and programs.

This is a step to add support for "make variables" when configuring.

26b05245f0 ec/curve25519.c: avoid 2^51 radix on SPARC.
SPARC ISA doesn't have provisions to back up 128-bit multiplications
and additions. And so multiplications are done with library calls
and carries with comparisons and conditional moves. As result base
2^51 code is >40% slower...

cfc32a1efb ec/curve25519.c: "double" ecdhx25519 performance on 64-bit platforms.
"Double" is in quotes because improvement coefficient varies
significantly depending on platform and compiler. You're likely
to measure ~2x improvement on popular desktop and server processors,
but not so much on mobile ones, even minor regression on ARM
Cortex series. Latter is because they have rather "weak" umulh
instruction. On low-end x86_64 problem is that contemporary gcc
and clang tend to opt for double-precision shift for >>51, which
can be devastatingly slow on some processors.

Just in case for reference, trick is to use 2^51 radix [currently
only for DH].

4a089bbdf1 Address a timing side channel whereby it is possible to determine some
information about the length of the scalar used in ECDSA operations
from a large number (2^32) of signatures.

This doesn't rate as a CVE because:

* For the non-constant time code, there are easier ways to extract
  more information.

* For the constant time code, it requires a significant number of signatures
  to leak a small amount of information.

Thanks to Neals Fournaise, Eliane Jaulmes and Jean-Rene Reinhard for

Centralize the entropy callbacks, from drbg_lib to rand_lib.
(Conceptually, entropy is part of the enclosing application.)
Thanks to Dr. Matthias St Pierre for the suggestion.

    -Make state an enum; inline RANDerr calls.
    -Add RAND_POLL_RETRIES (thanks Pauli for the idea)
    -Remove most RAND_seed calls from rest of library
    -Rename DRBG_CTX to RAND_DRBG, etc.
    -Move some code from drbg_lib to drbg_rand; drbg_lib is now only the
