Patch: Automatically run osmoload from osmocon

[Christian Vogel]

Hi,

I'm getting kind of annoyed by the new >64k firmwares that need
to be loaded via osmoload. Included patch #2 adds a "-a" option
to osmocon that runs an arbitrary script after the main firmware
has been successfully uploaded to the phone.

This script could, for example, then handle upload of a second
stage firmware via osmoload. Also layer23 could be started here
just before uploading layer1.

The script will be given the socket, serial port, loader method
(c123xor...) and main firmware as arguments, those can be used
to distinguish several phones that are connected to the same PC.

Example usage (using attached osmoload.sh script):

osmocon -p /dev/ttyUSB0 -m c155 -a .../osmoload.sh \
	.../board/compal_e99/loader.compalram.bin

Received DOWNLOAD ACK from phone, your code is running now!
OSMOCOM Loader (revision osmocon_v0.0.0-1299-g7c08201)
(---- 2 second delay ----)
[osmoload.sh] Socket is /tmp/osmocom_loader, port is /dev/ttyUSB0.
[osmoload.sh] Loader method was c155.
[osmoload.sh] New firmware will be
osmocom-bb/src/target/firmware/board/compal_e99/rssi.highram.bin.
Received pong.
