InfoBarGenerics: Only show pvr state when infobar is shown
Enable InfoBarInstantRecord menu in MoviePlayer
Use class name to determine if we are in the standard Infobar
Show also the instant recordings when in movie infobar
When closing standby screen also remove record_event

When the RecordTimerEntry Quitmainloop is activated while the box is in
standby when coming out if standby the notification is removed, but there
is still a record_event left in Navigation that still may shut down the
box after a recording event ends which is set as an auto recording.

Now also only the notification and the record_event is removed as the
RecordTimerEntry Quitmainloop is really activated.

Network.py: Remove unused imports, cleanup imports

Get rid of the evil rename-while-import like "from os import path as os_path"
Remove some imports and vars that weren't being used.
elock: Remove unused "pid" member
filepush: Use a condition instead of restarting a thread on skip

pause/resume is used (exclusively) to be able to skip. The contract
is that nothing is being written after "pause". Instead of stopping
the complete thread, just put the thread into a suspended mode using
a condition/mutex pair on "pause", and release it on "resume".

Starting a thread takes a whole bunch of resources, so needlessly
destroying and creating threads is really bad idea. This should
improve "skip" performance a bit, because the caller no longer needs
to wait for the filepush thread to start.

TODO: Capture the condition/mutex into a C++ class.
