In the file included with the bugreport, framerates were dropping from 60fps to
11fps for an armature with several lattices parented, and a 5fps drop everytime
an object was parented to the armature.
Upon (re-)inspection of the code, it became apparent that this was being caused
by a block of code that would recalculate the parent (perhaps recursively) as it
thought the parent state was for the wrong timestamp. However, the timestamps
this was using was never really updated (except for a single place, which set it
to a single fixed value to force recalculations to take place), which meant that
this branch was run all the time. AFACT, this is a remnant from some of the old
timeoffset stuff + pre-Depsgraph timestamping hacks that are no longer used/set.
===============================================
This patch adds a new "Character" BGE physics type which uses Bullet's btKinematicCharacter for simulation instead of full-blown dynamics. It is appropiate for (player-controlled) characters, for which the other physics types often result unexpected results (bouncing off walls, sliding etc.) and for which simple kinematics offers much more precision.
"Character" can be chosen like any other physics type in the "Physics" section of the properties window. Current settings for tweaking are "Step Height" (to make the object automatically climb small steps if it collides with them), "Fall Speed" (the maximum speed that the object can have when falling) and "Jump Speed", which is currently not used.
See http://projects.blender.org/tracker/?func=detail&atid=127&aid=28476&group_id=9
for sample blends and a discussion on the patch: how to use it and what influences the behavior of the character object.
Known problem: there is a crash if the "compound" option is set in the physics panel of the Character object.
* The operator creates bones for each input edge (does not subdivide
them like the skin operator does), adds a fake root bone for skin
roots with multiple children.
* The operator adds vertex weight groups to the original mesh.
* Make copy_object_transform() public, used to match the armature
object to the mesh object.

Additional changes:
* Fix for recent changes of BKE_* function renaming.
* Fix for an "attempt to free NULL pointer" in BlenderStrokeRenderer::RenderStrokeRepBasic().
Most of the changes are related to adding support for motion data throughout
the code. There's some code for actual camera/object motion blur raytracing
but it's unfinished (it badly slows down the raytracing kernel even when the
option is turned off), so that code it disabled still.
Motion vector export from Blender tries to avoid computing derived meshes
when the mesh does not have a deforming modifier, and it also won't store
motion vectors for every vertex if only the object or camera is moving.
- Make sure functions are named in way BKE_<object>_<action> (same way as RNA callbacks)
- Make functions which are used by mball.c only static and remove their prototypes
from public header file.
Further cleanup is coming.

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.
