This update added new revisions after undoing existing revisions. That is
to say, the old revision is not a strict subset of the new revision. This
situation occurs when you --force push a change and generate a repository
containing something like this:
* -- * -- B -- O -- O -- O (65df421c579737b9078a4ff637351ee1595cf85b)
\
N -- N -- N (d7b408faef5e52a406095383fcdea87533d734a0)
When this happens we assume that you've already had alert emails for all
of the O revisions, and so we here report only the revisions in the N
branch from the common base, B.
Those revisions listed above that are new to this repository have
not appeared on any other notification email; so we list those
revisions in full, below.

host/trxcon: handle ccch_mode from L1CTL_FBSB_REQ
Previously, the content of L1CTL_FBSB_REQ message was only used
to obtain a new ARFCN and retune transceiver. Now, since we have
working TDMA scheduler, some other params (like ccch_mode) may be
used too.

host/trxcon/scheduler: add basic clock counter
The core of scheduler is a simple clock counter, which relays
on system time for now. One was a bit simplified and migrated
from OsmoBTS.
Due to system time is not an ideal clock source, the counter
should be periodically corrected by clock indications from BTS.

host/trxcon: initial release of L1CTL handlers
Now it's possible to handle the following requests
from layer23 apps:
- L1CTL_FBSB_REQ
- L1CTL_PM_REQ
- L1CTL_RESET_REQ
- L1CTL_ECHO_REQ
It should be noted, that the L1CTL_PM_REQ isn't
handled correctly yet, due to required task isn't
implemented on the TRX side yet. Instead of this,
temporary we are sending some fake responses.

host/trxcon: integrate osmo-fsm framework
This change introduces the following state machines:
- trxcon_app_fsm - main application state machine.
This state machine handles different events, raised
from program modules (such as trx_if.c or l1ctl.c).
- l1ctl_link_fsm - L1CTL server state machine.
- trx_interface_fsm - TRX interface state machine.
The program modules (such as trx_if.c or l1ctl.c) should be as
much independent from each other as possible. In other words,
one module should not call methods from another, e.g. L1CTL
handlers are not able to send any command to transceiver directly.
Instead of that, they should use shared event set to notify the
main state machine about something. Depending on current state
and received event, main state machine 'decides' what to do. This
approach would allow to easily reuse the source code almost 'as is'
anywhere outside the project.

host/trxcon: initial release of L1CTL interface
There are two sides of the 'OsmocomBB <-> SDR' bridge. One of
them is the L1CTL interface, which is used by existing layer23
applications to drive GSM L1. Exactly this interface is provided
by the osmocon application, but instead of forwarding messages
between both host software and firmware we need to handle incoming
messages from layer23 applications, perform some GSM L1 specific
conversations (coding, mapping, interleaving, etc.), then finally
forward them to transceiver through the scheduler. And vice versa.
This code is just a basic implementation of UNIX socket handlers,
so currently we can only accept and drop connections from layer23
applications.

This app is similar to the osmocon, but designed to
connect L2 & L3 apps with SDR transceiver insted of
obsolete Calypso based hardware.
