specifically, this will skip the initial stop at _start when using the
terminal and remote adapters.

FIXME: if the attached to program has no relation to the currently
selected run configuration, the qt version config dialog will pop up
rather effectlessly and thus confusingly.

after refactoring the trk adapter startup, the split was not necessary
any more. in fact, it seemed fairly arbitrary at this point.

it is currently unused. do not just remove it, as hjk says he wants to
revive it.

- Turn off initial breakpoint when attaching (terminal) and
  additionally ignore it before the first startup complete
- Refuse to step  the artifical thread created when
  interrupting
- If possible, switch to thread 0 when interupting (do not
  use artificial thread)
- Ignore non-fatal exceptions in dumper calls (stray Startup-
  complete-traps)
- Use right thread for dumper call loading
- Rename windows exception code enumeration
- Turn off modification off watch-data children by setType,
  show empty lists correctly.
- Verbose warnings about inserting invalid watch data.

gdb can be started before the debugee, so do it. that's more in line
with the other adapters.

each command can have only one of two legitimate responses: "error" or -
depending on the command, and thus declared via a flag - "done" or
"running".
this is way nicer than sprinkling the code with else-ifs (where elses
are sufficient) and asserts all over the place - and silently failing in
release builds.

For the case that gdb can give all the interesting data in one go.

more verbose than base64 but also less work on the dumper side

These .pri files which add to INCLUDEPATH and have FORMS should also add
to DEPENDPATH.

Adding to INCLUDEPATH does not add to DEPENDPATH by default with qmake.
That means qmake may not find headers in those paths and won't
consider them dependencies when compiling the source files which include
them.

This doesn't matter when all the headers in the new INCLUDEPATH are
always present, but when some of them are generated (e.g. from FORMS),
the dependencies are important and omitting them means a race condition
in parallel builds.

Fixes errors of the form:
  ..\..\shared\help\topicchooser.h(33) : fatal error C1083: Cannot open
    include file: 'ui_topicchooser.h': No such file or directory
