This commit integrates the work done so far on the new dependency graph system,
where goal was to replace legacy depsgraph with the new one, supporting loads of
neat features like:
- More granular dependency relation nature, which solves issues with fake cycles
in the dependencies.
- Move towards all-animatable, by better integration of drivers into the system.
- Lay down some basis for upcoming copy-on-write, overrides and so on.
The new system is living side-by-side with the previous one and disabled by
default, so nothing will become suddenly broken. The way to enable new depsgraph
is to pass `--new-depsgraph` command line argument.
It's a bit early to consider the system production-ready, there are some TODOs
and issues were discovered during the merge period, they'll be addressed ASAP.
But it's important to merge, because it's the only way to attract artists to
really start testing this system.
There are number of assorted documents related on the design of the new system:
* http://wiki.blender.org/index.php/User:Aligorith/GSoC2013_Depsgraph#Design_Documents
* http://wiki.blender.org/index.php/User:Nazg-gul/DependencyGraph
There are also some user-related information online:

Kudos to everyone who was involved into the project:
- Joshua "Aligorith" Leung -- design specification, initial code
- Lukas "lukas_t" Toenne -- integrating code into blender, with further fixes
- Sergey "Sergey" "Sharybin" -- some mocking around, trying to wrap up the
project and so
- Bassam "slikdigit" Kurdali -- stressing the new system, reporting all the
issues and recording/writing documentation.
- Everyone else who i forgot to mention here :)
Currently this function only tags pose itself, totally matching previous
behavior. But this will be needed in the future once new dependency graph
is landed, because of it's granular nature which relies on the fact that
pose channels are all up to date when building the graph.
Should be no functional changes so far.
General idea is to avoid actual calculation from property update()
callback and tag things for update later instead.
That said, pose constraint flags are now tagged for update and
handled as a part of object update. In the new depsgraph it'll
be a nice dedicated operation node.
Also avoid updating disabled flags for all the modifiers. This
part of the path is not totally optimal since it'll still need
to iterate over bones in order to get pchan, but to optimize it
further would be nice to find a way to avoid pchan requirement
all together.

Propper fix reverting most of rB60e70c0c6014e5, which was only partial specific fix.
This code uses generic `BKE_id_lib_local_paths()` func to handle all possible paths.

To do so, matching BKE 'API' was also refactored a bit:
* Get Pose data instead of Object, as parameter;
* Removed some sanity checks not needed at such a low level (callers are supposed to do that);
* You can now remove an arbitrary bone group, not only the active one.
Based on patch by pkrime (Paolo Acampora), with own edits.

Previously this only worked for some datablocks relevant to rendering, now it
can be used to detect if any type of datablock was added or removed (but not
yet to detect if it was modified, we need many more depsgraph tags for that).
Most of the changes are some function parameter changes, the important parts
are the DAG_id_type_tag calls.

Summary:
Issue was caused by access to pchan->custom object from channel free
function when freeing all objects from main. Order of objects free
is not defined and such an access might easily end up with access
to freed memory.
We don't need to do user counter stuff when freeing main, so added
an _ex functions with do_id_user flag which is used when freeing main.
We had the same issue with other datablocks, so now it should be
easier to support relevant user counter.
This issue was caused by the fix for T36391, so perhaps that's indeed
high time to do real user counter.

GE was copying the pose channels without increasing user counter for a
custom bone shape object. Freeing copied pose will for give decrement
errors.
The same increment issue seems to happen in BKE_pose_copy_data, which
is also solved now.
Some places like proxy rebuild didn't increent
custom shape user counter which lead to user
decrement errors later when freeing pose channels.
Try to keep custom object counter relevent, but
some corner cases might still be missing.
decrement the object user count when removing the armature. This could cause
the object to stick when it shouldn't, in particular when that object is part
of a group.
Issue was caused by couple of circumstances:
- Normal Map node requires tesselated faces to compute tangent space
- All temporary meshes needed for Cycles export were adding to G.main
- Undo pushes would temporary set meshes tessfaces to NULL
- Moving node will cause undo push and tree re-evaluate fr preview
All this leads to threading conflict between preview render and undo
system.
Solved it in way that all temporary meshes are adding to that exact
Main which was passed to Cycles via BlendData. This required couple
of mechanic changes like adding extra parameter to *_add() functions
and adding some *_ex() functions to make it possible RNA adds objects
to Main passed to new() RNA function.
This was tricky to pass Main to RNA function and IMO that's not so
nice to pass main to function, so ended up with such decision:
- Object.to_mesh() will add temp mesh to G.main
- Added Main.meshes.new_from_object() which does the same as to_mesh,
but adds temporary mesh to specified Main.
So now all temporary meshes needed for preview render would be added
to preview_main which does not conflict with undo pushes.
Viewport render shall not be an issue because object sync happens from
main thread in this case.
It could be some issues with final render, but that's not so much
likely to happen, so shall be fine.
Thanks to Brecht for review!
now blenlib/BLI doesn't depend on any blenkern/BKE functions,
there are still some bad level includes but these are only to access G.background and the blender version define.
* Rename Legacy to Standard, it's not being deprecated as far as I know.
* Make option to toggle off Location solving work with Standard.
* Make it converge a bit better in some cases by enforcing a minimum number of
iterations before giving up.
* Move IK solver choice out of bone panel, it's an armature level setting and
should be set there.
Issue was happening when linking armature object and making proxy and was
caused by not copying visualization settings in BKE_pose_copy_data.
This lead to deadlocks in motion path drawing code.
After discussion with Campbell decided it is crucial fix since it fixes
bug appearing in really common scenario of using armatures.
Colors used by Bone Groups are now copied/assigned to Action Groups too when
they're created now. This completes the work started in r.46960 to restore this
functionality from 2.48.
Currently, there is no control over when/whether these colors are copied over
(although it is possible to disable the display of these colors for relevant
animation editors if desired). Originally I was going to make this a more
generic Keying Sets feature, though that turned out to be a bit too complex to
manage.
Other notes:
* Split out the code for copying colors to a common library function
Added four new functions as shortcuts to creating GHashes that use the
standard ptr/str/int/pair hash and compare functions.
GHash *BLI_ghash_ptr_new(const char *info);
GHash *BLI_ghash_str_new(const char *info);
GHash *BLI_ghash_int_new(const char *info);
GHash *BLI_ghash_pair_new(const char *info);
Replaced almost all occurrences of BLI_ghash_new() with one of the
above functions.
