Introduce POSIX data types
Introduce POSIX data types

POSIX provides portable data types for signed and unsigned integer values
of different size.

This patch maps those POSIX data types to the Tesseract specific types.
In a next step, the Tesseract data types can be eliminated by replacing
them with the POSIX data types.
