This patch changes the prototype for decode_base64 so that the encode / decode
method are consistant (encode(BYTE *) => char* and decode(char*) => BYTE*).
It also does some improvements with unrolling loops so that end conditions are
tested only at the end.
The patch also adds some unitary tests.
Before the patch base64_decode() made valgrind complain about uninitialized
bits, after valgrind is happy and very quiet.
Split version numbers into:
FREERDP_API_VERSION - the version of the API which is major.minor
FREERDP_VERSION - version of a release consisting of major.minor.revision (e.g. 1.1.0)
FREERDP_VERSION_FULL - like FREERDP_VERSION but with an optional "build" suffix (e.g 1.1.0-dev)
