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.
