Alessandro Gario 629e70287c Add CMake support, implement fuzzers (#284)
The new CMake project allows the user to select which SDK version
to use. The Xcode path is also configurable to support non-standard
installation paths and/or systems with multiple versions installed.

Code signing can now be configured via command line, using the
CODESIGN_IDENTITY environment variable.

New fuzzing targets (libFuzzer)
 - SantaCache
 - santactl
 - santad

New make targets:
 - tests: Runs the tests
 - fuzz: Runs the fuzzer
 - redist: Regenerates the redistributable folder
 - install: Installs Santa
