This library is wonderful, however, it's missing an explicit license in its source code. This adds the text of the MIT license along with the name of the original author. This helps folks like me make sure we follow the license terms when using this library. :)

Fix conflict with __int64_t typedef
...
On Linux, we get a compile error because __int64_t is defined and
included by stdint.h. Double underscores are reseved in C in general
and should not be used anyway. Replace with a single leading underscore.

Fix '-Werror=shift-negative-value' for gcc 6

GCC 6 introduced warning for shift on negative value numbers.
When F16C is called with a negative number it evaluates FIXMATH_COMBINE_I_M
with both the positive and the negative value.
