libosmocore has prefixed the timer functions with omso_* already
in May 2011 (0b21c1c8850d7f33f55d9399d14055a7cdda3614), and we follow
suit here for API consistency reasons.

This patch changes include paths to get osmocom-bb working with
the current libosmocore tree.
Among all these renames, you can notice several tweaks that I
added on purpose, and that require some explanation, they are:
* hexdump() in osmocon.c and osmoload.c has been renamed to avoid
clashing with hexdump() defined in libosmocore.
* gsmmap now depends on libosmogsm. Actually I had to cleanup
Makefile.am because I was experiencing weird linking problems,
probably due to a bug in the autotools. With the change included
in this patch, I got it compiled and linked here correctly.
This patch has been tested with the phone Motorola C123 and the
following images files:
* firmware/board/compal_e88/hello_world.compalram.bin
* firmware/board/compal_e88/layer1.compalram.bin
Using the osmocon, bcch_scan and mobile tools.

Some real issues are still left and we need to act on them.
|
|
* remove linuxlist.h copy and use osmocore
* don't put 'struct gsm_time' into l1ctl packets
* include rx_level and snr for each burst in l1ctl
* properly build libosmocore.a for target
* move gsmtime functions into libosmocore
* move ctype.h to standard location

We now support arbitrary timers by means of 'struct timer_list'.
Any part of the program can register such a callback by means
of schedule_timer() on a millisecond-granularity. However, there
is no guarantee on the timer precision. It will not execute before
the timer expires - but it might expire quite a bit later than we
have asked it for, depending on how busy the cpu is with other work.
The timer code is in the 'comm/' directory, as it is intended to be
migrated into libosmocore soon.
Furthermore, as we currently don't yet have a scheduler or tasks,
the main() routine explicitly has to call update_timers() to check
for any expired timers and run them.

L1 and L2 now pass UI frames like BCCH and CCCH downlink up into
L3, which detects an IMMediate ASSignment command and instructs
the L1 to switch to SDCCH/4.
From this point on, SDCCH/4 and SACCH4/C messages end up in our
L2 LAPDm implementation and are forwarded to L3.

Using #define TPU_DEBUG, we can now send the full TPU RAM contents
to the host PC (using a sercomm DLCI) at the time of tpu_enable()
which is very helpful for TPU debugging.
