Convert Travis build configuration to a single var instead of 4 tuple.
Makes it much easier to review the builds in the Travis web UI.
Adds sanitizer builds for Clang on both Linux and OS X. Clang is a different
compiler from GCC and its sanitizers may catch things GCC does not.
I have no idea if Apple's Clang has some magic sanitizer sauce stock
LLVM does not, so maybe sanitizer build on OS X can be skipped.
Adds Linux cross compile targets for ARM32, ARM64, PPC64, and MinGW x86
using the cross compiler available in Trusty. All of them build and are
set up to run through qemu/wine. All of the tests currently fail and
so are marked as expected fail in the Travis matrix.
The ARM test runs seem to have thread problems; ARM32 thread creation just fails
with an exception, as if pthreads was disabled. All other tests pass ok for ARM32.
On Aarch64, it looks like there is a hard crash the first time the library tries
creating a thread. Both of these might be due to statically linking the binary?
I have been unable to convince Ubuntu's qemu-ppc64 to execute binaries compiled by
Ubuntu's ppc64 cross compiler. I'm downloading an Ubuntu ISO to try this in a VM.
Running under Wine exposes several issues, both in Wine and Botan. Many functions are
stubs and it appears that entropy collection fails as a result. This triggers a bug
in the FFI tests which causes a crash there.
A pox on time zones; _mkgmtime is a MSVC extension and is not available on MinGW GCC.
Add a last resort call that just uses the localzone variant instead.
Adds valgrind target, remove a bogus poison in pubkey.cpp (it was effectively
asserting that all of RSA was const time which is sadly not true at all).
Moves -Wshadow to maintainer mode for GCC - GCC 4.8 has a noisy variant of -Wshadow
which warns if a parameter masks a function name, but this comes up all the time
in constructors. Later GCCs no longer warn about this (even with -Wshadow), so the
warnings are never fixed, but they cause noise in CI output and hide interesting
warnings like
warning: vec_lvsl is deprecated for little endian; use assignment for unaligned loads and stores [-Wdeprecated]
__vector unsigned char perm = vec_lvsl(0, static_cast<u32bit*>(nullptr));

Change reseed interval logic to count calls to `randomize` rather than
bytes, to match SP 800-90A
Changes RNG reseeding API: there is no implicit reference to the
global entropy sources within the RNGs anymore. The entropy sources
must be supplied with the API call. Adds support for reseding directly
from another RNG (such as a system or hardware RNG).
Stateful_RNG keeps optional references to both an RNG and a set of
entropy sources. During a reseed, both sources are used if set.
These can be provided to HMAC_DRBG constructor.
For HMAC_DRBG, SP800-90A requires we output no more than 2**16 bytes
per DRBG request. We treat requests longer than that as if the caller
had instead made several sequential maximum-length requests. This
means it is possible for one or more reseeds to trigger even in the
course of generating a single (long) output (generate a 256-bit key
and use ChaCha or HKDF if this is a problem).
Adds RNG::randomize_with_ts_input which takes timestamps and uses them
as the additional_data DRBG field. Stateful_RNG overrides this to also
include the process ID and the reseed counter. AutoSeeded_RNG's
`randomize` uses this.
Officially deprecates RNG::make_rng and the Serialized_RNG construtor
which creates an AutoSeeded_RNG. With these removed, it would be
possible to perform a build with no AutoSeeded_RNG/HMAC_DRBG at all
(eg, for applications which only use the system RNG).

Add OS functions get_process_id, get_processor_timestamp, and
get_system_timestamp_ns. HMAC_RNG uses the pid call to detect forks to
initiate a reseed. It also adds the output of all three functions (the
pid, the CPU cycle counter, and the system timestamp) into the PRF input.
Calls the new OS timer functions from hres_timer entropy source.
Removes the call to QPC in es_win32 which is mostly redundant with the
one in hres_timer.

Provide abstractions for the locking allocator (allocate and free
locked pages) to decouple it from the platform dependent code. Should
make it easy to write a Windows version using VirtualAlloc+VirtualLock.
Exposes max mlock limit as a build.h toggle
