* Remove unnecessary moc includes.

This commit removes moc file includes for some classes which do not
define new qt classes. This caused a long standing warning which seems
to be treated as error on some setups.

* Make (in)sanity check happy.

Here you got your bloody spaces. Uber picky, isn't it?

* Remove QAudio::interruptedState again

Sailfish version of QT doesn't feature this yet.

* Fix:debug:Change line separators for dbg to work also on win* platform

* Fix:debug:Break multiline dbg statements to use the new model

* Fix:debug:Move the EOL into debug_vprintf

* Add: Add speech module using (external) espeak on QMultimedia.

* Add: Find system espeak or use internal one

This patch adds a cmake module to find installed libespeak.
If not found, it builds against included libespeak, despite it being
heavily patched.

* Fix: allow building internal espeak for posix systems

Allow the usage of the internal (ported to C) version of espeak as
replacement for system installed libespeak.

* Fix: use synchronous espeak mode if internal espeak is used

* Fix: Clear buffer if samples are played

* Fix: use syncronous mode always, as QBuffer is not thread safe

* Sailfish: Use qt5_espeak

* Remove espeak shell script now obsolete

* Fix: remove the espeak script from the repo

* Fix: code cleanup. Fix audio buffer size

* Fix: apply coding style

Apply automatic coding style with 'clang-format -style=WebKit -i'

* Fix; restore correct include file order

Seems, our internal include files depend on correct order. This usually
is a bad thing and we should consider fixing them. But this is another
story...

* Add qtmultimedia-dev to windows build for qt5_espeak

* Rename CMake INTERNAL_ESPEAK -> INTERNAL_ESPEAK_COMPLETE
