This argument was used to prevent infinite loop in lookups between disk
and RAM cache.
Code was refactored, so this can be handled internally in cache.

Error handling added in 512a23c3d6 caused that reading header of new
file failed, since it is empty.
Don't attempt to read header if file is empty. If header can not be read
anyway, try to delete the file. Add asserts, as this should never
happen.

Respond to return values of `fscanf()` and `fread()` to detect and
handle I/O errors. Not only is error handling a good idea, this also
prevents warnings from GCC that `fread()` and `fscanf()` return values
are ignored.

This value was meant to be used for keeping images that are slowest to
render in cache. Method of measurement was flawed, because it doesn't
take UI overhead into consideration.
Cache panel is to be removed because users should not have to tweak
settings like this. It is not useful for development either, therefore
it is removed completely.
If image is cached twice, it's size has been counted twice as well, but
only image reference count is increased, not memory usage.
Use `MEM_get_memory_in_use()` instead of size own tracking.
Move most functions into separate files.
File sequencer.c is reserved for alloc, free and duplicating functions.
There should be no functional changes.
Variables renaned:
- cfra -> timeline_frame
- nr -> frame index
- cfra_over -> overlap_frame
Function seq_give_stripelem_index was renamed to seq_give_frame_index.
Map frame for cached raw images to strip input media frame range. This
means that static images or extended frame range of movies will only
generate one cache entry.
timeline_frame is stored in cache key as a reference - on what frame
was this entry created, so we don't have to reverse lookup frame range.
Since each media frame corresponds to one cache frame with same frame
index key, there is no need to invalidate raw cache when changing time
remapping properties like use_reverse_frames or strobe
No changes are needed for disk cache, since invalidating raw entry
assumes all data will be invalidated.

Intern definitions are moved to sequencer/intern/sequencer.h
BKE_sequencer.h was also cleaned up a bit to make sure that functions
and structs are in correct category.
