987903826b Globally rename the header inclusion guard names. 
Consistently apply this rule: the guard name is obtained from the
filename by stripping the leading "lib", converting '/' and '.'  to
'_' and uppercasing the resulting name. Guard names in the root
directory have to be prefixed by "FFMPEG_".

24c4eff657 Rework link property configuration system. 
This can now handle filters which are added to graphs out of order,
including auto-inserted scale filters.  As an added bonus, it can
now detect circular filter chains which wouldn't work anyway.

b3ab2f7e84 Add another "reuse" permission, to distinguish between the case where a 
source filter will simply want to re-output the same image multiple times
and reuse a buffer to do it, and the case where the source filter will
output multiple image by modifying a single buffer and outputting it multiple
times.

52f97a0d8d Track the permissions that have been given out to each picture. 
This should make it easier to know what can be done to a buffer once
it's been passed to your filter without falling back to copying it "just
to be safe".
