Various type mismatches in CF

Describe the bug CF source code has a number of type mismatches that may or may not be picked up by the compiler (due to platform variations).

In particular:

List traversal functions (CF_CListFn_t used by CF_CList_Traverse() have a custom return type, it is not CFE_Status_t)
Channel action functions (CF_ChanActionFn_t have a custom return type, it is not CFE_Status_t)
Numerous mismatches between int and long and the printf format specifiers

To Reproduce Build on a platform which does not match assumptions about type equality

Expected behavior Build should succeed

System observed on: Debian, RTEMS 4.11
