Neels Hofmeyr c3f72f63af dyn TS: fix: ts_subslots() for TCH/F_PDCH in PDCH mode 
In gsm_data_shared.c, add ts_pchan() to determine actual pchan type for dynamic
and non-dynamic TS.

Use in ts_subslots() to fix the value returned for TCH/F_PDCH in PDCH mode.
Adjust the assertion in channel_test.c accordingly.

Drop GSM_PCHAN_TCH_F_PDCH, which is now handled in ts_pchan().
Explicitly add GSM_PCHAN_PDCH as zero in subslots_per_pchan[] (cosmetic).
Adjust the comment in subslots_per_pchan[].

The fix for the number of subslots affects only one caller: bts_chan_load() in
chan_alloc.c. Before this, it would always include a TCH/F_PDCH in the
load_counter->total, now it is skipped when in PDCH mode. Whether this is the
way bts_chan_load() should handle dynamic TS is a separate discussion, so far
I'm only making sure that the two dyn TS kinds act in the same way:
TCH/F_TCH/H_PDCH is only counted when in TCH mode, and TCH/F_PDCH should match.

About OpenBSC
=============

OpenBSC started as a minimalistic all-in-one implementation of the GSM Network,
with particular emphasis on the functionality typically provided by the BSC,
MSC, HLR, VLR and SMSC.  Today it is a growing suite of libraries and programs,
implementing protocol stacks and functional elements, including

 * OsmoBSC - a pure GSM BSC, speaking Abis/IP to the BTS and A/IP to the MSC
 * OsmoBSC-MGCP - MGCP helper to the OsmoBSC software
 * OsmoNITB - a BSC+MSC+VLR+HLR+SMSC "Network in the box".
 * OsmoCSCN - a voice CN with A/IP and IuCS/IP towards the BSC and/or HNB-GW
 * OsmoSGSN - a GPRS SGSN with Gb/IP and IuPS/IP towards the PCU and/or HNB-GW
 * Osmo-GbProxy - a Proxy to aggregate many Gb links as one Gb link to the SGSN
 * OsmoBSCNAT - a gateway aggregating many A links as one A link to the MSC
 * OsmoGTPHUB - a hub aggregating many GTP links (between SGSN and GGSN)
 * ipaccess-utils - some tools to discover + configure ip.access nanoBTS
 * bs11_config - a tool to configure the Siemens BS-11 microBTS

Various interfaces towards the BTS are supported, among which are:

 * Classic A-bis over E1 using a mISDN based E1 interface. In other
   words, you can connect existing GSM Base Transceiver Station (BTS)
   through E1 to OpenBSC.  So far, we have made it work with the Siemens BS-11,
   various Ericsson RBS2xxx BTS models and the Nokia MetroSite.

 * A-bis over IP as used by the ip.access nanoBTS product family as well as
   the Open Source OsmoBTS software (by the same authors as OpenBSC).  OsmoBTS
   in turn supports various transceiver hardware, including the sysmoBTS
   product family, as well as SDR transceivers supported by OsmoTRX, such as
   the UmTRX or USRP boardss.

 * IuCS and IuPS over IP towards an HNB-GW (see osmo-iuh) for UMTS (3G)
   voice and data links.
