lib: Use packed struct for FRCT header access

This replaces the variable FRCT header with a packed struct, which
significantly simplifies the implementation. The shm_du_buff calls to
release the head/tail are updated to return a pointer to the original
head or the new tail (in symmetry to the alloc calls, which return a
pointer to the new head and old tail), so that it immediately points
to the structure that is needed.

The frct_pci sources are removed and frct is now fully in the frct.c
source file.
