Remove the paragraph about writing to the Free Software Foundation's
mailing address. The FSF has changed addresses in the past, and may do
so again. In 2021 this is not useful, let's rather have a bit less
boilerplate at the start of source files.

This way the layer1 can activate proper CBCH task and send us
CBCH block with proper RSL channel number, so they do not end
up being routed to LAPDm and rejected there.

We cannot blindly assume that CBCH is present on TS0/SDCCH4 before
decoding CBCH Channel Description in System Information Type 4.

In Change-Id Ia94ebf22a2ec439dfe1f31d703b832ae57b48ef2 we
introduced a new member to the ccch_mode enum: CCCH_MODE_COMBINED_CBCH,
which is to be used to tell the PHY if a CBCH is present on the combined
CCCH+SDCCH/4+CBCH or not (CCCH+SDCCH4).
This was implemented in trxcon + calypso firmware, but cbch_sniff has
not been updated accordingly.

As Dieter points out, this drastically improves the resiliance to high
receive levels on the C155. We cannot blindly assume a received signal
level of -85 dBm if the BTS is 2m away and we actually receive -40 dBm.
This patch extends the L1CTL_FBSB_REQ data structure in layer 1 with the
respective field, as well as the l1ctl_tx_fbsb_req() API function called
from the various layer23 apps.
"mobile" and "bcch_scan" already did a PM request and thus know the
expected signal power. "ccch_scan" and "cbch_sniff" apparently don't
do, so the -85 dBm constant is now hardcoded into the host-side source
code there, and should probably be fixed in a follow-up patch.
Since libosmocore already has LAPDm implementation, we don't need the
local copy of LAPDm code anymore.

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.

Make it possible that each l23 app can inject the copyright string,
also prepare to have callbacks for the config handling and other
places. This will be useful to add app specific config options.
Tune to the ARFCN specified on the commandline (-a). Then, if
a CBCH Channel Description IE is found in System Information Type 4,
switch to dedicated mode on that particular channel to receive
the CBCH.
