Add bit map encoder and decoder functions: decoder is fully functional
while encoder is good enough for testing - no backtracking to find
the best possible compression is implemented. If somebody is willing to
implement MS side of EDGE than this has to be expanded.
Add corresponding tests.
N. B: the encoding is implemented according to ETSI TS 44.060 which is
slightly different from T4 used for fax according to CCITT G31D (RFC 804).

Shipping our own private copy of talloc was a good idea in 2008,
when it was not readily available on most target platforms. Today,
the situation is quite different, as it is a standard library on
major Linux distributions.

This commit moves the stats specific code parts into stats_statsd.c
while keeping the generic parts in stats.c. The code in stats.c no
longer contains references to statsd symbols.
Note that the VTY code still needs to know about every stats reporter
backend.

This commit provides the stats reporting framework that can manage
several types of measurement reporters. Initially support for
rate_ctr and the statsd protocol is included.

This commit adds instrumentation function to gather measurement
and statistical values similar to counter groups.
Multiple values can be stored per item, which can be retrieved in
FIFO order. Getting values from the item does not modify its state to
allow for multiple independant backends (e.g. VTY and statd).
When a new value is set, the oldest value gets silently overwritten.
Lost values are skipped when getting values from the item.

Preprocessor flags are best placed in AM_CPPFLAGS. Remove use of the
unused all_includes variable, which is never set.

This enables the persistent configuration of let's say
'log filter imsi 012345678' for a given log file in the config

FreeBSD 10.0 ships an execinfo.h but one needs to link to an
additional library for the backtrace functions. Check if there
is a backtrace symbol in libexecinfo and if so link to that
library.

Only the Gb library relies on having undefined references to a
symbol that needs to be provided by the host application. For
all other libraries we can link with -no-undefined.

I noticed some more issues and it is the easiest to revert and include
the fixed version.
This reverts commit 73377229bb33ab79682ce4b126a63602d13304ad.

This actually allows for the user to override the decision and at the
same time supports compilers that might not be able to use -fPIC at
all.

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.

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.

* 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.

per network code messages. This will be used for various

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.
