Linux offers file descriptor based periodic (interval) timers,
which can achieve a higher precision than our userspace based
timers and which can be slave'd to CLOCK_MONOTINIC or other clock
sources. Let's add some code for osmo_fd wrapped versions that
integrate well with our select() abstraction.
The code has been used in osmo-bts-trx since June 2017 (change-id
I51b19adde14ebb7ef3bb863d45e06243c323e22e), and I'm just renaming
and moving it to libosmocore here. After a merge, the osmo-bts
implementations can be removed in favor if this one.

This basically follows the concept of osmo_timer_setup() and allows
the caller to fill-in all configurable fields of osmo_fd in one
line of code, rather than open-coding it in 5 lines everywhere.

This is a convenience helper that will both close a fd, mark it as
closed and unregister it from the event loop abstraction. In most
cases, you probably actually want to use it instead of manually closing
and calling osmo_fd_unregister().

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.

osmo_fd_register() is used to register socket file descriptors,
after registering a socket, there is no way to test if the socket
is still registered or actually registered at all.
This commit adds a new function osmo_fd_register_check() that can
be used to check in advance, if the socket fd is registered,
before performing further operations.

To integrate with an external event loop (in this case glib) we
need to allow an application to get a filled out fd_set and then
dispatch it. osmo_fds and maxfds are static and I decided to keep
it that way and instead create two routines to fill the fdset and
then one to dispatch the result.
The public header file does not include sys/select.h and we can
compile the library without select, so I didn't want to require
having to include this file, and used void * for the parameter.
Mark the routines as inline to avoid a call from the select
function. I have confirmed that inlining has an effect on x86
using Debian's gcc-4.9.2-10 compiler
This function can be used to obtain the osmo_fd corresponding to a given
fd. The latter can be useful when integrating libosmocore main loop
with other libraries.
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'.
