The global int pointer 'Running' is just a hack for global access of

ProgData::running. We can get rid of this global.

include/rmdtypes.h: Put ProgData in JackData so that the libjack stuff
can access progam state.

src/recordmydesktop.c: Initialize ProgData member of JackData.

src/rmd_jack.c: Use ProgData instead of the global.

src/register_callbacks.[ch]: Pass ProgData to the registering of
signal handlers and put a local version of the Running-global hack in
this file.

src/rmd_rescue.c: Get rid of Running-logic and pass ProgData to
RegisterCallbacks()

src/rmdthreads.c: Pass ProgData to RegisterCallbacks()

src/initialize_data.c: Get rid of Running-logic.

include/recordmydesktop.h: Remove the Running-global.
