src: use new libosmogsm and include/osmocom/[gsm|core] path to headers

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.
