This patch contains the following possible cleanups:
- make needlessly global code static
- remove the compiled but unused st5481_hdlc.{c,h}
- kill enternow.h
- enternow_pci.c: kill InByte/OutByte/BYTE
- isdnl2.c: kill FreeSkb
- remove or #if 0 the following unused functions:
- config.c: IsdnCardState
- ipacx.c: ipacx_new_ph
- ipacx.c: dch_bh
- ipacx.c: setup_ipacx
- isdnl2.c: IsRR
