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 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.

For the host build the local_irq_save/_restore is a NOOP
and the compiler warns about the unused flags variable. Cast
it to void to avoid compiler warning.
For some reason, at least on the C123, a sequence of multiple NUL bytes
seems to get corrupted somewhere in the Rx side on the phone itself (the
NUL plus the following character get dropped).
We now simply work around this issue by having our sercomm/HDLC layer
escape all NUL octets in the stream.
If we're transmitting a to-be-escaped character as the last byte of the
buffer, the code generated the sequence ESCAPE FLAG rather than
ESCAPE last_byte FLAG.
This fixes the bug.
* 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
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.
