From the patch:
This patch enables drag and drop parenting for objects in the outliner.
Drag and drop is supported for a selection of multiple objects as well. Also,
all of the "special" parenting tasks (armature, curve, lattice) are possible
through the usual parenting context menus. For example, drag a mesh object onto
an armature and you are prompted for using bone envelopes, automatic weights,
etc.

This commit extends limit of ID and objects to 64 (it means 63 meaning
characters and 1 for zero-terminator). CustomData layers names are also
extended.
Changed DNA structures and all places where length constants were hardcoded.
All names which are "generating" from ID block should be limited by MAX_ID_NAME-2,
all non-id names now has got own define called MAX_NAME which should be used all
over for non-id names to make further name migration stuff easier.
All name fields in DNA now have comment with constant which corresponds to
hardcoded numeric value which should make it easier to further update this
limits or even switch to non-hardcoded values in DNA.
Special thanks to Campbell who helped figuring out some issues and helped a lot
in finding all cases where hardcoded valued were still used in code.
Both of forwards and backwards compatibility is stored with blender versions newer
than January 5, 2011. Older versions had issue with placing null-terminator to
DNA strings on file load which will lead to some unpredictable behavior or even
crashes.
Regression was introduced in svn rev40343. It was caused by re-creating
EditMesh structure which was needed to solve issues with parenting to
vertices after topology changes. This would also erase derivedMesh.
Problem reported now is caused by missing derivedMesh which is used
to solve parenting and apply inverted matrix on ob->parentin, so
parented object used to stay at exactly the same position it used to
stay before parenting.
Not very nice solving of this issue: re-create derivedMesh after
re-creating EditMesh when parenting. Nicer solution would require
bigger changes and probably ful lrefactor of this tools.
incompatible, and unmaintainable Time Offset cruft.
- Slow Parenting lives another day (just), although it now carries
appropriate cautionary disclaimers. It's only really for the Game
Engine nowadays, as that's the only place where it can possibly work
with any reliability.
- "Animation Hacks" panel is now "Relations Extras". I could've merged
the two panels, though I figured these options weren't that frequently
used to justify taking up screen-space by default along with the panel
The only way to achieve this is to re-load editMesh.
After this commit you can't iterate through vertices and insert
hooks/parents from script anymore -- this operators are now
treated as topology-changing and shouldn't be used when iterating
via geometries.
Such load/make edit structures introduced regression into iterators
via object's geometry (vertices, edges, control points and so) when
adding hooks in the body of this iterator.
Fix for wrong index should be non-destructable for geometry.
This will fix#28506: Unusual behavior in curves.
Use quite easy and stupid approach like it used for shape keys:
re-make editmesh (editcurve or editlattice) before creating index array
for hook or storing vertex index in parenting object.
Even if hook was added in "current" edit mode, it should be re-mapped on
loading edit data because topology could be changed after it was created.
Such kind of re-loading edit structures is the easiest way for now to
update keyindexes to relevant state.
Also, fixed bug with not re-mapping indices for vertex-parented objects.
Really old error, not sure why it wasn't noticed yet.

It seems that some of the Outliner hacks used while building the tree
was causing problems, as Make Single User (and potentially other code
working with ID-data, specifically with the "newid" value there) was
making use of the variable used there for other purposes, leading to
memory corruption.
This bug also occurred in 2.4x, though when I tested there, it crashed
immediately.
Ton, you may want to double-check this bug!
also minor functional changes
- OBJECT_OT_make_links_data() type property is now assigned to the operator property (so popup menu can find it)
- removing BG image now returns cancelled if no image is removed.
