Neels Hofmeyr 17518fe393 doxygen: unify use of \file across the board
Considering the various styles and implications found in the sources, edit
scores of files to follow the same API doc guidelines around the doxygen
grouping and the \file tag.

Many files now show a short description in the generated API doc that was so
far only available as C comment.

The guidelines and reasoning behind it is documented at
https://osmocom.org/projects/cellular-infrastructure/wiki/Guidelines_for_API_documentation

In some instances, remove file comments and add to the corresponding group
instead, to be shared among several files (e.g. bitvec).

Neels Hofmeyr 33370cb18d doxygen: various fixes in core/timer.h
Move a longish comment to the timer group so that it appears in the API doc.

Un-doxygen some floating comments that were associated with unrelated code
items ('/**' --> '/*').

Add braces to some function names so that the API doc will render as reference
links.

Neels Hofmeyr 87e4550585 doxygen: enable AUTOBRIEF, drop \brief
Especially for short descriptions, it is annoying to have to type \brief for
every single API doc.

Drop all \brief and enable the AUTOBRIEF feature of doxygen, which always takes
the first sentence of an API doc as the brief description.

Pablo Neira Ayuso 44f423f117 timer: add osmo_timer_setup()
Add a new function timer function to set up the timer, similar to what
we have in the Linux kernel. This patch also converts existing opencoded
timer setup in the libosmocore tree as initial client of this new
function.

This patch implicitly removes function callback passed by reference that
defeat compile time type validation.

Compile-tested only, but I ran make check that reports success when
testing timer infrastructure.

Neels Hofmeyr 8e2f7e87f4 add osmo_gettimeofday as a shim around gettimeofday
This allows feeding a custom time for unit tests by overriding
osmo_gettimeofday.

Pablo Neira Ayuso 066c912fd3 timer: add scalable RB-tree based timer infrastructure
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.

Pablo Neira Ayuso 8341934844 include: reorganize headers file to include/osmocom/[gsm|core]
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'.
