[L] Change in libosmo-abis[master]: e1d: reconnect to osmo-e1d after connection loss

by dexter

Attention is currently required from: laforge, pespin, keith, dexter. Hello Jenkins Builder, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/libosmo-abis/+/32374 to look at the new patch set (#14). Change subject: e1d: reconnect to osmo-e1d after connection loss ...................................................................... e1d: reconnect to osmo-e1d after connection loss When osmo-e1d crashes while a line is in use the client process may experience not only a lost connection, it may also hang up in an endless loop that would also spam the logfile. The reason for this is that the e1d driver in libosmo-abis lacks mechanisms to detect when the connection to osmo-e1d gets lost. When osmo-e1d goes down the effects should be similar to those of a normal connection loss of an e1 line (cable pulled). So let's add an FSM that takes care of the recovery of the connection when it is lost. Also make sure that no havoc happens when the connection gets lost.
