auto_profiles: unapply conditional profiles if declared

Browse Source 
Uses the mechanism introduced in the previous commit. The hope was to
make auto-profiles easier to use, and to get rid of the need for
manually created inverse profiles. Not sure if the end result is useful.

@ -789,8 +789,14 @@ Whenever a property referenced by a profile condition changes, the condition
is re-evaluated. If the return value of the condition changes from false or
error to true, the profile is applied.
Note that profiles cannot be "unapplied", so you may have to define inverse
profiles with inverse conditions do undo a profile.
This mechanism tries to "unapply" profiles once the condition changes from true
to false. If you want to use this, you need to set ``profile-restore`` for the
profile. Another possibility it to create another profile with an inverse
condition to undo the other profile.
Recursive profiles can be used. But it is discouraged to reference other
conditional profiles in a conditional profile, since this can lead to tricky
and unintuitive behavior.

If you want the profile to be reverted if the condition goes to false again,
you need to do this by manually creating an inverse profile:
you can set ``profile-restore``:
::
[something]
profile-desc=Flip video when entering fullscreen
profile-desc=Mess up video when entering fullscreen
profile-cond=fullscreen
vf=vflip
profile-restore=copy
vf-add=rotate=90
[something2]
profile-desc=Inverse of [something]
This appends the ``rotate`` filter to the video filter chain when entering
fullscreen. When leaving fullscreen, the ``vf`` option is set to the value
it had before entering fullscreen. Note that this would also remove any
other filters that were added during fullscreen mode by the user. Avoiding
this is trickier, and could for example be solved by adding a second profile
with an inverse condition and operation:
::
[something]
profile-cond=fullscreen
vf-add=@rot:rotate=90
[something-inv]
profile-cond=not fullscreen
vf=
This sets the video filter chain to ``vflip`` when entering fullscreen. The
first profile does not cause the filter to be removed when leaving
fullscreen. A second profile has to be defined, which is explicitly applied
on leaving fullscreen, and which explicitly clears the filter list. (This
would also clear the filter list at program start when starting the player
in windowed mode.)
