The MovieSequence and MovieClip classes now have a metadata() function
that exposes the `IDProperty *` holding the video metadata.

This is useful to create a mapping from the frame range in the video to
frame index in the blend file.

This is currently only supported by FFmpeg (so not frameserver, AVI RAW,
or AVI JPEG), and only seems to work when using Matroska or Ogg Theora
containers.
Only metadata that doesn't change from frame to frame is written to
video files. This distinction is visible in the UI by looking at the
stamp checkbox tooltips (they either mention "image" or "image/video").

- Metadata handling is now separate from `ImBuf *`, allowing it to be
used with a generic `IDProperty *`.
- Merged `IMB_metadata_add_field()` and `IMB_metadata_change_field()`
into a more robust `IMB_metadata_set_field()`. This new function
doesn't return any status (it now always succeeds, and the previously
existing return value was never checked anyway).
- Removed `IMB_metadata_del_field()` as it was never actually used
anywhere.
- Use `IMB_metadata_ensure()` instead of having
`IMB_metadata_set_field()` create the containing `IDProperty` for
you.
- Deduplicated function declarations, moved `intern/IMB_metadata.h` out
of `intern/`. Note that this does mean that we have some extra
`#include "IMB_metadata.h"` lines now, as the metadata functions are
no longer declared in `IMB_imbuf.h`.
- Deduplicated function declarations, all metadata-related declarations
are now in imbuf/IMB_metadata.h.

Free code should not handle ID refcounting at all. This has to be done
at higher level, since in some case we want to free (temp) data that
actually did not refcount at all its IDs.
This change seems to be working OK, but as usual in that area, only
lots of testing in real-case situation will say whether there are some
hidden bugs or not.
This is a part of copy-on-write sanitization, to avoid all the checks
which were attempting to keep sub-data pointers intact.
Point is: ID pointers never change for CoW datablocks, but nested
data pointers might change when updating existing copy.
Solution: Only bind ID data pointers and index of sub-data.
This will make CoW datablock 7update function was easier in 2.8.
In master we were only using pose channel pointers in callbacks,
this is exactly what this commit addresses. A linear lookup array
is created on pose evaluation init and is thrown away afterwards.
One thing we might consider doing is to keep indexed array of
poses, similar to chanhash.

- Use a single undo history for all operations.
- UndoType's are registered and poll the context to check if they
should be used when performing an undo push.
- Mode switching is used to ensure the state is correct before
undo data is restored.
- Some undo types accumulate changes (image & text editing)
others store the state multiple times (with de-duplication).
This is supported by checking UndoStack.mode `ACCUMULATE` / `STORE`.
- Each undo step stores ID datablocks they use with utilities to help
manage restoring correct ID's.
Needed since global undo is now mixed with other modes undo.
- Currently performs each undo step when going up/down history
Previously this wasn't done, making history fail in some cases.
This can be optimized to skip some combinations of undo steps.
grease-pencil is an exception which has not been updated
since it integrates undo into the draw-session.
See D3113
- See `--log` help message for usage.
- Supports enabling categories.
- Color severity.
- Optionally logs to a file.
- Currently use to replace printf calls in wm module.
See D3120 for details.
- Get memory usage from MemFile instead of MEM API
avoids possible invalid when threads alloc memory.
- Use size_t instead of uint and uintptr_t to store size.
- Rename UndoElem.str -> filename
- Rename MemFileChunk.ident -> is_identical
Undo sometimes reserved too much space in the buffer,
now assert when this happens and allocate the exact size needed.
Note prepares for moving text editor undo out of the text block (D3113)
which will split the undo buffer into a list of undo steps.
We had a mix of two issues here actually:
* First, Brush are currently using their own sauce for custom previews,
this is not great, but moving them to use common ImagePreview system of
IDs is a low-priority TODO. For now, they should totally ignore their
own ImagePreview.
* Second, BKE_icon_changed() would systematically create a PreviewImage
for ID types supporting it, which does not really makes sense, this
function is merely here to 'tag' previews as outdated. Actual creation
of previews is deferred to later, when we actually need them.
For IDProps IDarray, IDP_EqualsProperties was called for each item,
instead of IDP_EqualsProperties_ex, discarding value of `is_strict`
option.
Probably not an issue with current code, though.
Each AnimData block has a set of Blend/Extrapolation/Influence settings
that can be used to control how the active action is blended with the
NLA stack. However, these settings were not getting copied over to the
newly created strips (as the push-down code existed long before these
settings were added).
This commit solves this in several ways:
* Active Action Blend/Extrapolation/Influence settings now get copied
to the new strips when adding them to the NLA stack via Push Down.
Note: This doesn't happen when there are no existing NLA tracks,
as these settings don't get used in that case.
* Strip Influence will be copied across when inf < 1.0 (i.e. when a
non-default value is used), to maintain the effect. To make this work,
the influence value will get added as a keyframe to the strip's
"Influence" Control FCurve.
- See code comments for an alternative approach and why that was not chosen
- Strip Time still doesn't get keyframes added automatically yet.
* To ensure the "extrapolation mode" settings don't get always overwritten,
I've put in place a compromise: the extrapolation will only get changed
if the chosen setting will cause problmes (i.e. hold forward & back -> hold forward
if there are other tracks before it already).
Not safe for backporting to 2.79[x] stable releases.

Main purpose is to make it possible to cover FPS detection with regression test.
But it might also be handy for some other scripters.
Thanks Campbell for review!
This is probably a better way to handle it: instead of totally
discarding scaling of non-free axes, keep the ratio between them.
Basically the logic of the constraint is now that it rescales the
object uniformly in the non-free axis plane in order to force the
total volume change to the desired value.
