Introduce a new crypto/ directory that will (eventually) contain
all the cryptographic related code. This initially defines a
wrapper for initializing gnutls and for computing hashes with
gnutls. The former ensures that gnutls is guaranteed to be
initialized exactly once in QEMU regardless of CLI args. The
block quorum code currently fails to initialize gnutls so it
only works by luck, if VNC server TLS is not requested. The
hash APIs avoids the need to litter the rest of the code with
preprocessor checks and simplifies callers by allocating the
correct amount of memory for the requested hash.

Providing a default level of parallelism is perfectly fine, but it
should also be possible to set higher or lower levels of parallelism
easily. This is particularly beneficial for people packaging the
software for Linux distributions.
- in appveyor, install clang and cmake in cygwin, enable package upgrades, and build cmocka and enable testing for gcc only
- in `gitignore`, ignore generated cmocka folder
- in travis, use brew in osx to install cmocka, and enable testing for gcc and clang on os x and linux
- in `Makefile`, change to use `uname -s` to determine os type
- make `install-cmocka-linux.sh`, a simple shell script to download and install cmocka on linux
- in `bindings/Makefile`, enable `make -c` to call subdirectory makefiles instead of `cd [dir] && make` and include environment variables for runtime access to generated libraries
- in `samples/Makefile`, change to use `uname -s` to determine os type, remove `clean_bins` from `all` command, and include `Werror` for compile strictness
- in `tests/unit/Makefile`, add `cflags` for compile time access to cmocka headers and library, include execute vars for runtime access to cmocka and unicorn libs
- in `tests/unit/test_tb_x86.c`, comment out assert that would not compile
Now that LIBRARY is the versioned name (e.g. "libunicorn.so.0"), we
don't need this rename step; just create the symlink for libunicorn.so.
If VERSION_EXT isn't set, then the library we installed already has the
correct name, and no symlink is necessary.
We should probably be running 'ldconfig' to handle this, or better yet,
using libtool.
This allows executables (e.g. unit tests) to link against the
libunicorn.so in the build directory, after the SONAME was added in
4860fdb3.
Becuase libunicorn.so has an SONAME of libunicorn.so.0, the linker uses
the SONAME for the DT_NEEDED entry of the tests. But because a library
with that name did not exist, they would fail to run.
