It was supposed to be a feature for substituting RNA paths on the
fly, but has never been implemented, apart from a couple of structure
definitions and passing around some always-NULL pointers. Now it gets
in the way of refactoring NLA evaluation to use GHash for efficiency.
NLA strips are users of their action, so we need to pass along ID
management flags.
This commit also cleans up a bit things by passing along ID_CREATE/COPY
flags instead of dummy booleans...
This way we allow animation system to make decisions based on which
context dependency graph is coming from, and whether it belongs to
an active edit window or not.
The depsgraph was always created within a fixed evaluation context. Passing
both risks the depsgraph and evaluation context not matching, and it
complicates the Python API where we'd have to expose both which is not so
easy to understand.
This also removes the global evaluation context in main, which assumed there
to be a single active scene and view layer.

2.8x branch added bContext arg in many places,
pass eval-context instead since its not simple to reason about what
what nested functions do when they can access and change almost anything.
Also use const to prevent unexpected modifications.
This fixes crash loading files with shadows,
since off-screen buffers use a NULL context for rendering.
This will allow much finer controll over how we copy data-blocks, from
full copy in Main database, to "lighter" ones (out of Main, inside an
already allocated datablock, etc.).
This commit also transfers a llot of what was previously handled by
per-ID-type custom code to generic ID handling code in BKE_library.
Hopefully will avoid in future inconsistencies and missing bits we had
all over the codebase in the past.
It also adds missing copying handling for a few types, most notably
Scene (which where using a fully customized handling previously).
Note that the type of allocation used during copying (regular in Main,
allocated but outside of Main, or not allocated by ID handling code at
all) is stored in ID's, which allows to handle them correctly when
freeing. This needs to be taken care of with caution when doing 'weird'
unusual things with ID copying and/or allocation!
As a final note, while rather noisy, this commit will hopefully not
break too much existing branches, old 'API' has been kept for the main
part, as a wrapper around new code. Cleaning it up will happen later.

This aims at always ensuring that ID.newid (and relevant LIB_TAG_NEW)
stay in clean (i.e. cleared) state by default.
To achieve this, instead of clearing after all id copy call (would be
horribly noisy, and bad for performances), we try to completely remove
the setting of id->newid by default when copying a new ID.
This implies that areas actually needing that info (mainly, object editing
area (make single user...) and make local area) have to ensure they set
it themselves as needed.
This is far from simple change, many complex code paths to consider, so
will need some serious testing. :/
Drivers can use this to refer to the data which the driver is applied to,
useful for objects, bones, to avoid having to create a variable pointing to its self.
This commit changes a lot of how IDs are handled internally, especially the unlinking/freeing
processes. So far, this was very fuzy, to summarize cleanly deleting or replacing a datablock
was pretty much impossible, except for a few special cases.
Also, unlinking was handled by each datatype, in a rather messy and prone-to-errors way (quite
a few ID usages were missed or wrongly handled that way).
One of the main goal of id-remap branch was to cleanup this, and fatorize ID links handling
by using library_query utils to allow generic handling of those, which is now the case
(now, generic ID links handling is only "knwon" from readfile.c and library_query.c).
This commit also adds backends to allow live replacement and deletion of datablocks in Blender
(so-called 'remapping' process, where we replace all usages of a given ID pointer by a new one,
or NULL one in case of unlinking).
This will allow nice new features, like ability to easily reload or relocate libraries, real immediate
deletion of datablocks in blender, replacement of one datablock by another, etc.
Some of those are for next commits.
A word of warning: this commit is highly risky, because it affects potentially a lot in Blender core.
Though it was tested rather deeply, being totally impossible to check all possible ID usage cases,
it's likely there are some remaining issues and bugs in new code... Please report them! ;)

Reviewed by campbellbarton, thanks a bunch.
FCurve evaluation depended on FCurve.curval, which isn't threadsafe.
Now only use this value for debug display,
and pass the value instead of storing in the FCurve for all but debug-display.
This commit only adds callbacks which then later be used with major dependency
graph commit, keeping the upcoming commit more clean to follow.
Should be no functional changes so far still.
Finally! At long last, I've gotten this working! This ended up being far trickier
to get right than anticipated; the normal remapping API's cannot be used as-is
as they will just clobber over subtleties whenever datablock changes are involved.
So, for now, we have to duplicate the logic a bit.
Currently, when joining two armatures, the drivers of the armatures being merged
in are lost. This commit introduces a new AnimData API function for merging
animation data into another AnimData block.
NOTE:
* For now, this only copies the drivers over. As a result, manual effort will
still be needed to go through and fix the drivers.
I am working on automating that process, but it's more important that the
drivers don't have to be created from scratch for now (since this is needed
for the Goosberry rigging work).
This is only a (hacky) partial fix, actually, since `RNA_property_animated()` will still
not work in those cases... Better that than nothing, though.
Thanks to Campbell for review.
This fix adds a "ref_id" ID pointer to BKE_all_animdata_fix_paths_rename() & co, which is the ID against which prefix+oldName/NewName is "applied", currently only used for drivers' bones targets. Just pass NULL to get same behavior as previously. A bit annoying to make such a change for such a specific case, but there seems to be no other way to go... :/
*Add a new idname to keyingsets, keeping name as label-only (using same string for both made lookup fail when using i18n other than english, as it tried to compare an untranslated static string id against a translated RNA name). Also adding a description string (can be helpful with custom keyingsets, imho).
*Fixed a few other bugs related to that area (namely, you can’t deselect current keyingset from the shift-ctrl-alt-I popup menu, and insert/delete key ops were using a rather strange way to get chosen custom keyingset…).
*Fixed UI code so that it always uses (RNA) enum, and simplified menu-creation code.
