Lionel Gauthier c60dc45b2b Changed uX, uX_t sX, sX_t to uinX_t 
Cleaned some PDCP/driver code

types parameters and vars

Please see openair2/COMMON/platform_types.h for simple coding rules.

please declare prototypes of functions in .h and include .h files in where the function is used and where it is implemented.
