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. git-svn-id: http://svn.eurecom.fr/openair4G/trunk@5096 818b1a75-f10b-46b9-bf7c-635c3b92a50f
