Apparently __FILE__ expands to nasty '../../..' paths when BUILDDIR !=
SRCDIR. This in turn leads to ugly log lines like:
<0000> ../../../../osmo-bts/src/common/rsl.c:1642 (bts=0,trx=0,ts=0,ss=0) Handing RLL msg UNIT_DATA_IND from LAPDm to MEAS REP
Where we certainly wouldn't want the "../../../../osmo-bts" part.

Move those routines from OpenBSC to libosmogsm, so they can be
re-used from other programs. I think it was a mistake to add them only
inside the openbsc repository in the first place. We need to pay more
attention to this in the future.

This adds and improves doxygen API descriptions all over libosmocore,
reducing the 'white spots' that don't have any documentation.

This is e.g. quite useful to call at the end of test code, in order to
show that all memory allocated actually is released before exit().

Currently the LOGP/DEBUGP arguments are always evaluated even if
no logging will happen at all. This can be expensive, for instance
if hexdumps or pretty printed object names are generated. This causes
high base load especially on embedded devices and is a major part of
CPU usage e.g. of the osmo-pcu.
This commit uses the log_check_level function to avoid the evaluation
of the parameters if it is known in advance, that no logging entry
will be generated.

This commit adds this predicate function which can be used to
avoid the execution of code if a certain log level is not enabled.
The function will only return 0 (false), if it is sure that a logging
call for the same facility and level will not produce any output.
This safety criterion shall ensure, that no logging output is lost
due to the use of this predicate as a guard. On the other hand, even
if the predicate returns != 0 (true), no logging output might get
generated by a similar logging command.
Note that the current implementation is not focussed on performance,
which could be improved by using a lookup table instead of iterating
through every target.

This log level is used by the stats subsystem log reporter to report
statistics to level INFO. Note that the default level of DLSTATS is
NOTICE.

We want to see from which category/subsystem a certain log message
is coming from and use a different timestamp format as well. Add
two new bitfields. This doesn't change the size of the structure
and on 32bit we still have 27bits left.
The extended timestamp will take preference over the current and
default timestamp format.
Fixes: SYS#602

and reserve a global region here.

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

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

Doxygen generates quite a lot of warnings on libosmocore. Some of them
are obvious typos - this patch aims to fix such low-hanging fruit.

Introduce a print_filename attribute for each logtarget. Initialize it
with 1 to be backward compatible with earlier versions. The bit is taken
from an existint bitfield. There were at least six bits left of the byte.

Applications should keep the log area in a static const area. Mark
the pointer as const to address compiler warnings in OpenBSC, cast
the const away for the osmo_log_info as it is not declared as const.

Make sure the declaration and definition match, add const to
the functions called by logp/logp2.

this patch i use to suppress warnings when compiling osmo-pcu (c++).
since __FILE__ is constant, the called logging function with parameter
"file" must be constant too, in order to avoid compiler warnings.

This bug was introduced in 95f7eb288c4b8b69d61fa8d68957fb21f09e11e5 and
it caused a segfault on 'write terminal'

They are not used anywhere in our libraries, so they should be defined
by the respective applications

|

* 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 adds the libosmo-abis logging subsystems to libosmocore,
it uses the new change that harald proposed based on negative
numbers for library logging subsystems.

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 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'.
