* ID-blocks referenced by Constraints but not being used as the target objects
(such as Actions in the Action Constraint, or Text Blocks in PyConstraints) now
get usercounts for being referenced in this way. This should fix ancient bugs
such as [#19205] and [#8593]. More tests still needed to verify that this
does now play nicely with proxies.
* Changing actions used by NLA strips should now update the usercounts
accordingly

This makes debug output easier to read - event debug prints would flood output too much before.
For convenience:
--debug-all turns all debug flags on (works as --debug did before).
also removed some redundant whitespace in debug prints and prefix some prints with __func__ to give some context.
Issue was caused by object moved really far away (not just actually issue,
it's just about long mouse gesture and X-axis orientation which projects
position to quite large X-axis value) and for this location start offset
from curve length was calculating iteratively which takes plenty of time for
short curves.
Replace iterative search of offset with formula which seems to be working
in the same way and should be a bit more accurate.
- spelling - turns out we had tessellation spelt wrong all over.
- use \directive for doxy (not @directive)
- remove BLI_sparsemap.h - was from bmesh merge IIRC but entire file commented and not used.
Now constraints' space conversion code also uses generic armature_mat_(pose_to_bone/bone_to_pose). Previous own function (constraint_pchan_diff_mat) was somewhat inconsistent too with Hinge/NoScale/LocalLocation options...
As with previous similar changes, this might break some old rigs, in very specific cases (when constraint-evaluating an hinge/noscale/local_location bone in local space).
In the same part of code, removed unnecessary matrices copying, mult_m4_m4m4 can take the same matrix as input and output, nowadays...
Also found a bug-generator weakness in those armature_mat_ functions (if both input and output mat where the same, result was wrong, now systematically copying input mat, as done in LIB's matrix funcs).
Finally, factorized offset bone matrix generation into its own small function too, as it is used in two different places in armature.c (pchan_to_pose_mat itself, and restpose's where_is_armature_bone).
Note: I think all parts of blender's code related to that topic have now been tackled, but yet have to check BGE, it’s probably using that stuff too, one way or the other...
It was incorrect behavior of contarget_get_mesh_mat in cases when
object's Y axis is co-linear to average vertex group normal.
Use object's X axis for plane definition in such cases.
Org code was working with isotropic scaling, but when scaling only one axis, it was broken. First fix just disabled completly scale handling. This version only takes into account scaling along local Y axis, as this is the only one affecting that constraint!
Sorry for the mistake, hope this time it will be ok.
- in the case of deform modifiers this is very safe (assuming the mods themselves dont need tessface data), since the DM is freed right after, so this is an easy speedup.
- in the case of bevel and split edge modifiers this should still work out fine since mods that need tessface data will generate it.
If this object is defined, object with Follow Track constraint would be
projected into surface of this depth object.
If object is not set or there's no projection onto it, projection plane
calculated based on original object position would be used.
This allows to make cheap facial mocap.
This commits merges object tracking implementation from tomato branch.
Summarized changes from branch:
- Added list of objects to be tracked. Default there's only one object called
"Camera" which is used for solving camera motion. Other objects can be added
and each of them will have it;s own list of tracks. Only one object can be used
for camera solving at this moment.
- Added new constraint called "Object Tracking" which makes oriented object be
moving in the save way as solved object motion.
- Scene orientation tools can be used for orienting object to bundles.
- Object has got scale to define "depth" in camera space.
- All tools which works with list of tracks or reconstruction data now
gets that lists from active editing object.
- All objects and their tracking data are available via python api.
- Improvements in witness cameras workflow,
inconsistent with similar functions & math notation:
mul_m4_m4m4(R, B, A) => mult_m4_m4m4(R, A, B)
mul_m3_m3m4(R, B, A) => mult_m3_m3m4(R, A, B)
For branch maintainers, it should be relatively simple to fix things manually,
it's also possible run this script after merging to do automatic replacement:

Object used to be parented to active camera which isn't very convenient when
working with witness cameras.
Now parent camera can be specified in constraint (if it's not specified, active camera is used)
Made Object Solver operator parent object to scene's camera. Behavior is pretty much
familiar to Child Of constraint -- it stores inverted transformation matrix which gives
constant offset in parent's space.
Current files would open incorrect, to make object aligned well again, just press
"Set Inverse" button in Object Solver constraint.
Fixed orientation operators so now they should work in all cases.
Also changed behavior of Set Origin operator which now sets origin to the median
point of all selected tracks/
