22ca9c0197 Fix preprocessor checks for bn_mul PPC asm
On OS X, neither __powerpc__ nor __ppc__ is defined on PPC64, so the
asm code was only being used on PPC32.

e63560470e Don't try to use MIPS32 asm macros on MIPS64
The MIPS32 bn_mul asm code causes segfaults on MIPS64 and failing
tests. Until someone has time to fix this up, MIPS64 platforms should
fall back to the C implementation (which works fine).

08f06cf49f Disabled the HAVEGE random generator by default
Rationale: The HAVEGE random generator has too many caveats to be a
standard generator that people rely on. The HAVEGE random generator is not
suitable for virtualized environments. In addition the HAVEGE random
generator is dependent on timing and specific processor traits that
cannot be guaranteed by default on compile time.

Our advice: only use HAVEGE as an additional random source for your
entropy pool, never as your primary source.

The new function ssl_set_ciphersuite_for_version() sets specific entries
inside this array. ssl_set_ciphersuite() sets all entries to the same
value.

e81beda60f The SSL session cache module (ssl_cache) now also retains peer_cert information (not the entire chain)
The real peer certificate is copied into a x509_buf in the
ssl_cache_entry and reinstated upon cache retrieval. The information
about the rest of the certificate chain is lost in the process.

As the handshake (and certificate verification) has already been
performed, no issue is foreseen.
