Add a new core/defs.h file for definitions that can be used from
within header files without including prototypes and extern
declarations. It's primarily meant for macro definitions and basic
typedefs.
Move the definition of OSMO_DEPRECATED there and use compiler version
info to avoid compiler errors.

this causes compiler warnings in user code ever since commit

The modified macro is still working on a gcc 4.7 and gcc 4.8 after the
removal of the typedef and addition of the unused attribute.

This is changing the semantic of the assert. The regression tests
now either need to check the stderr result, the exit status or print
a message when all tests are completed.
This is not that bad as the osmo_generate_backtrace is printing to
the stdout right now.

This function will re-open all existing log files in the application,
praticularly useful for SIGHUP handlers in case of logrotate
|

The tests should unconditionally assert, regardless of debug settings.
This uses the OSMO_ prefix as it's in the global namespace.

The log target can be used via log alarms and show alarms.

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.

msgb_pull returns a pointer to the new begin of the
buffer, unlike msgb_get(), where those functions
were originally taken from.

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.

msgb_get() has been wrong all the time, despite the documentation being
correct. If you've used the broken msgb_get() before, you have to
change your code now, sorry.

Add parentheses around the OSMO_MAX and OSMO_MIN macro to match
the behaviour of calling a function. The current version does not
evaluate to what is expected. (OSMO_MAX(3, 2) + 13) currently
results in 3 and not 16.

I recently discovered that we can only print backtraces to stdout, which
is of course useless in a daemon environment. We'd rather want to use
the libosmocore logging framework instead.

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.

There is no real reason to keep the include directory a multi-level
recursion, so instead declare everything within include (so that we
can use proper nobase_ declarations) and be it.
Please note that since we removed the sub-Makefile.am, ./configure
will not create the directory structure for us on out-of-tree builds,
so we have to make sure the directory we're generating to exists first.

As requested by Mike Morrin <Mike.Morrin@ipaccess.com>, we introduce
GSMTAP sub-types for all the different GPRS and EGPRS coding schemes.
This is neccessary due to the fact that the RLC PDU doesn't contain any
explicit indication of the coding scheme used on the radio layer.

Note that this breaks the ABI and the low level API. But it shouldn't
break the high level API, nor the conv code definitions (because fields
default to 0, and for new fields '0' is the previous behavior)

As it turns out, if a project uses the old name but without a declaration,
it'll causes a segfault on 64 bits platform (because of the implicit
int return type which doesn't apply since here it's a pointer).

----
The 'rb_first()', 'rb_last()', 'rb_next()' and 'rb_prev()' calls
take a pointer to an RB node or RB root. They do not change the
pointed objects, so add a 'const' qualifier in order to make life
of the users of these functions easier.
Indeed, if I have my own constant pointer &const struct my_type *p,
and I call 'rb_next(&p->rb)', I get a GCC warning:
warning: passing argument 1 of ?~@~Xrb_next?~@~Y discards qualifiers from pointer target type

This patch adds RB-tree based timers which scales better than the
previous list-based implementation.
It does not require any API changes. It breaks ABI because the
osmo_timer_list structure has changed though (to avoid this in
the future, we can put internal data in some private structure).
The following table summarizes the worst-case computational complexity
of this new implementation versus the previous one:
rb-tree list-based
------- ----------
calculate next timer to expire O(1) O(n)
insertion of new timer O(log n) O(n)
deletion of timer O(log n) O(1)
timer-fired scheduler O(log n) O(3n)
The most repeated cases are:
* the calculation of the next timer to expire, that happens in every
loop of our select function.
* the timer-fired scheduler execution.
This new implementation only loses in the deletion of timer scenario,
this happens because we may need to rebalance the tree after the
removal.
So I think there is some real gain if we have some situation in which
we have to handle lots of timers.

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.
