Using the NULL context creates mem leaks that bother sanitizer builds.
Allocate as talloc "child" of the rate_ctr_group, so that the mangled desc (if
any) gets freed when the rate_ctr group is freed.
Remove the comment concerning osmo-msc: the way to fix the unexpected talloc
state in osmo-msc tests is to have no invalid rate counter names in osmo-msc.
See Ib1db8e3dc6c833174f1b0b1ca051b0861f477408 (osmo-msc).

Let's fix some erroneous/accidential references to wrong license,
update copyright information where applicable and introduce a
SPDX-License-Identifier to all files.

In Change-Id Ifc6ac824f5dae9a848bb4a5d067c64a69eb40b56 we introduced
a variable de-reference before we check if it's NULL.
Let's reorder the statements to avoid this.
Fixes: Coverity CID#178219

As rate counters are automatically exposed on the CTRL interface,
we need to make sure they don't contain special characters such as '.'
which are not permitted/supported by CTRL.
In order to be able to run old versions of osmocom programs with
libosmocore versions after this commit, we introduce some special
name mangling: Any '.' in the names are replaced with ':' during
counter group registration, if valid identifiers can be obtained
this way.

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).

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.

It's a pity that even with this patch we still are fare away from having
the whole API documented. However, at least we have a more solid
foundation. Updates not only extend the documentation, but also make
sure it is rendered properly in the doxygen HTML.

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.

Currently the counters are scanned twice, once for interval
computation and once for reporting.
This adds a reminder to move the interval computation code to a
special stats reporter which just shall update the fields.

For global value reporting, some additional helper functions are
needed. The statsd protocol expects differential counter values,
which are currently not provided by rate_ctr (except for s/m/h/d
intervals).
This commit adds several helper functions to rate_ctr:
- rate_ctr_difference returns the counter delta since the last
call to this function for a given counter
- rate_ctr_for_each_counter
iterates through each counter of a group
- rate_ctr_for_each_group
iterates through all globally registered
counter groups
Note that the rate_ctr_difference function can only be used by a
single backend, since it modifies the 'previous' field in the
rate_ctr obj.

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'.

There should not be any u_int*_t types in this file, no need
to include this file. It is breaking compilation with the last
x86 build of GNU ARM for GCC 3.4.
If a second ends, we add the number of events in that just-ended second
to the number of events in the currently running minute. The same happens
at the end of a minute: We add the number of events in that just-ended
minute into the number of events of the still-running hour, etc.
This gives a much more meaningful numbers and we don't end up with
"12 events per second, but 0 events per minute" kind of situations
anymore.
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.
