Philipp Maier 524e3e3170 octphy: integrate channel measurement handling 
recent octphy firmware versions do support proper channel measurement handling.
The new implementation replaces the old, and for osmo-bts non functional
implementation.

This commit introduces the necessary adjustments. Older firmeware releses will
still work. However, the measurement computation results will still be wrong.

Harald Welte d784e50747 Introduce new phy_link and phy_instance abstraction 
This way we can model a flexible mapping between any number of PHYs,
each having multiple instances, and then map BTSs with TRXx on top of
those PHYs.

Harald Welte 866f9b979d OCTPHY: Obtain information from PHY and expose it in VTY 
This adds 'show trx 0 system-information' command to the VTY indicating
various version information obtained from the DSP/PHY.

Harald Welte 3e98f942e5 OCTPHY: Implement command re-transmission after message loss 
We re-use the 'wait_l1_conf' structure for implementing the
unacknowledge command window towards the PHY.  This means that thre will
unconditionally be a 'wait_l1_conf' now, even for requests where the
caller didn't provide a call-back.

Harald Welte 0c017618cd OCTPHY: Block PHY indications until it is confirmed open 
When re-starting OsmoBTS after unclean shutdown, the PHY is already
sending notifications (PH-DATA.ind, PH-TIME.ind, etc.) for the previous
physical channel / timeslot configuration.  At the point those messages
are received, OsmoBTS might not even have A-bis OML up yet, and thus has
no clue how to process such messages (and subsequently likely crashes).

Let's block such primitives from passing further up the code until we
have received the TRX-OPEN response.

Harald Welte b92100ad36 Add support for Octasic OCTSDR-2G GSM PHY 
This adds support for a new PHY to OsmoBTS, the Octasic OCTSDR-2G
PHY. This is a proprietary GSM PHY running on a familty of Octasic DSPs.
