* All loging prefixes in libraries should be DL like DLINP
* All signals / subsystems should be called S_L_* SS_L_*
* All command nodes should be called L_*_NODE
This makes sure existinc code still compiles as expected
This patch adds a new attribute to msgb objects. This new
attribute will store a pointer to the routing information,
in the case of the A-bis link, this will be used to store
e1inp_sign_link instead of struct gsm_bts_trx.
This deprecates msg->trx, that can be removed once all
application are ported to use msg->dst.
This adds the libosmo-abis logging subsystems to libosmocore,
it uses the new change that harald proposed based on negative
numbers for library logging subsystems.
The first range (from 0 to INT_MAX/2) of signal subsystems can be
used by client applications while the second range (from INT_MAX)
is reserved for libraries.
This is useful to support signals defined in libraries that
may be used by different client applications.
We do this by using a trick: library-internal log categories use
negative subsystem numbers, which are converted into positive
array indexes at the time of logging.
library-internal log categories need to be knwo at compile-time,
while application-specified categories now are of unlimited number,
as they are dynamically allocated.
This extends the socket infrastructure in libosmocore to allow
to create non-blocking sockets.
Basically, it replaces the connect0_bind1 parameter by one
flags parameter.
osmo_sock_init_ofd() is a wrapper around osmo_sock_init() which will
take care of initializing and registering a 'struct osmo_fd' for the
newly-created socket.
* use write_queue where applicable
* provide functions that work on raw FD and those with osmo_fd
* add support for multiple gsmtap instances (no global variables)
The plan is to collect structs and routines for application
setup and remove many copies of the boilerplate code we have
right now. This starts with routines to ignore certain signals
and the stderr init code.
Increment the age of the library because a new interface was added.

minor glitch included in this patch while I was at it:
-#include "linuxlist.h"
+#include <osmocom/core/linuxlist.h>
This can be helpful where we send GSMTAP messages to the loopback
device (localhost, 127.0.0.1) from where the kernel would then
send ICMP reject packets as nobody is listening on that port.
Far from perfect but suits our need thus far.
The viterbi with softbit input is quite cpu-intensive. Since
most received bursts are often mostly error free, you could
use a less cpu intensive algorithm (Fano ?) and with hard bit
input. Then only switch to viterbi soft bit input if the channel
is bad enough to justify it.
Soft output is not implemented as its usefulness for the block
coding is limited.

This patch moves all GSM-specific definitions to include/osmocom/gsm.
Moreover, the headers in include/osmocore/ have been moved to
include/osmocom/core.
This has been proposed by Harald Welte and Sylvain Munaunt.
Tested with `make distcheck'.
