* We now consistently avoid punctuation when possible
* Renamed usage of "Inferior" and "Program" to "Application" for
increased readability
* Fixed inconsistent spacing in front of statusbar label

as it turns out, it is not possible to set pending breakpoints until
gdb has loaded as image. so add some hooks to enable adapters to trigger
the initial breakpoint syncing at the right time. do not add additional
states (say, InferiorPreparing), as it would just complicate things.
this includes:
- move the gdb ownership back to the engine (thus strip down the
adaptors as far as possible)
- make gdb startup synchronous
- make adapter shutdown synchronous
- fix the state transitions relating to shutdown
