The PDCH class and corresponding functions are rather self-contained and
independent from BTS implementation. Let's move them into separate file
to make bts.cpp more manageable. As additional benefit it allow us to
somewhat untangle all the different cross-dependent includes.

Many files include unnecessary headers and don't include headers which
are actually used. Because of that combined with the fact that OsmoPCU
is a mixture of C and C++, it makes it hard to modularize code. Fix
this (using iwyu [1] tool):
* add missing headers
* remove unused headers

* initialize with invalid TA instead of making assumption that phone is
located within 550 meters (TA=0)
* only set valid TA

The commit 506f156f7a has reverted the
TS search order. The outer loop exit condition was not updated
accordingly. This bug would would only lead to an error if there were
multiple TRX where the first TRX has not got any PDCH assigned.
This commit corrects the break condition.

Currently the search for an enabled PDCH slot for SBA start with the
first TS. If there are more than 2 PDCH slots enabled, this slot will
conflict with an existing multislot reservation for most multislot
classes. This were less likely if the search were reversed and
started with the last slot due to the 3 slot shift between Tx and Rx.
When multislot allocation is enabled and several MS are connected,
and increased rate of poll timeouts can be observed.
This commit tries to reduce the number of poll timeouts by reverting
the slot search order for SBA allocation.

Simplify the reset code now that the PDCH can know where it is
located. Rename the variables in the sba to trx_no and ts_no as
it stores the number and not the actual thing.
The PollController is a friend of the SBAController and is allowed
to access the internal list. The list is hidden from everyone else.
This is done because the calculation of timeout should belong into
the PollController and not into the SBAController.
