We don't need to hand-code unix domain socket initialization but
can simply use our library function for it. As an added benefit,
the library code already contains corner case handling for non-NUL
terminated unix domain socket path.

Variables are not removed as they document the commands of the
propietary romloader.
Let's mark them as unused to avoid compilation warnings.

It disables undesirable signals such as SIGPIPE, which exits the program
if the client connected to osmocon closes the connection and osmocon
writes to the connection fd. After SIGPIPE is disabled, write returns
-EPIPE.
This is required to keep osmocon running for BTS_Tests.ttcn TTCN3 tests.

Bugfix in Osmoload.c: Assigning correct value to data pointer in
LOADER_MEM_READ. Wrong value was introduced in last update when
msgb_get() was replaced by msgb_pull() which returns end of data instead
of start of data.
We alias the uint8_t buf[..] to a uint16_t* which is violating
the aliases rule of C. Use an explicit memcpy to copy the first
two byte of the buffer. GCC 4.6.2 (debian) is clever enough to
use a normal load does not generate a memcpy call.
osmocon.c: In function ‘un_tool_read’:
osmocon.c:1239:2: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]
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.

Beacons with the default 50 mS interval are too far apart to
be picked up by the OpenMoko gta0x Calypso chip. Make them
configurable via a -i commandline argument.
As recommended in the OpenMoko wiki[1], an interval of 13 mS works.

The idea is to load a small application to the phone, which
activates and executes the Calypso romloader. The payload
itself then is loaded with the romloader, bypassing the magic
and the resulting size limit on the C139/C140 and J100i.
