alloca.h is not available on FreeBSD, use the default autoconf
function to check for it, there is a complete list[1] of what to
do for using alloca but let us see how far we get with this test.
Include netinet/in.h for the IPv4 and IPv6 socket address. Check
for dlopen in libraries and use this instead of linking -dl.

With the new generated headers for the CRC code, we need to include
the builddir as well in case we're building out of tree.

This patch adds red black trees implementation to libosmocore.
This data structure is very useful to search for elements in
ordered sets in O(log n) instead of O(n) that lists provide.
The first client of this code will be one follow up patch that
implements rbtree-based timer scheduler.

* 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.

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.

libosmogsm which is provided by libosmocore.
I have also moved generate_backtrace() to backtrace.c instead
of gsm_utils.c, otherwise the timer and msgfile tests depend on
libosmogsm.

This file format will be used to store per country code,
per network code messages. This will be used for various
things ranging from access control, to messages...

These routines come from OpenBSC, the msgb_wrap_* functions
belong to Mike Haben, the rest is mine. The msgb allocation
is compatible to the GSM48 allocation in OpenBSC.

Use SUBDIRS to build src first and the src/vty. We will need
to find the right way add the dependencies.

This also includes an option for a minimal 'infinite loop' type
panic that could be required for embedded target that don't have
abort() or fprintf()

A 'rate counter' is a counter that counts events but also keeps
track of the rate of events (per second, minute, hour and day).
'rate counters' are generally abstracted in 'rate counter groups',
which are instances of a 'rate counter group description'. This
way we can have e.g. a description describing what kind of counters
a BTS (or TRX) has - and we can then create one instance of that
group for every BTS or TRX that exists.

It's not really about debugging, but about generic logging...

The write queue can be a dropin replacement for the bsc_fd. It
is featuring two callbacks. One for ready read and one for ready
write. Whenever there is a message in the queue the write_queue
will set the BSC_FD_WRITE flag and then call the write callback.
It will make sure to delete the msgb after the write function
has been called. This class is intended to be be used in the
osmocom, layer2, bsc_msc_ip, bsc_hack and other applications.
