Idea is, instead of ignoring completely missing linked datablocks, to
create void placeholders for them.
That way, you can work on your file, save it, and find again your missing data once
lib becomes available again. Or you can edit missing lib's path (in Outliner),
save and reload the file, and you are done.
Also, Outliner now shows broken libraries (and placeholders) with a 'broken lib' icon.
Future plans are also to be able to relocate missing libs and reload them at runtime.
Code notes:
- Placeholder ID is just a regular datablock of same type as expected linked one,
with 'default' data, and a LIB_MISSING bitflag set.
- To allow creation of such datablocks, creation of datablocks in BKE was split in two step:
+ Allocation of memory itself.
+ Setting of all internal data to default values.

This patch introduces a couple new stroke modifiers. The ones currently implemented are based on prototypes by @kjym3 and myself.
The new modifiers:
- Tangent
- Thickness noise
- Crease Angle
- Simplification
- Curvature 3D
The documentation for these new modifier types can be found [[ http://www.blender.org/manual/render/freestyle/parameter_editor/index.html | in the manual ]]:

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.

The reported issue was caused by a backward incompatibility due to careless
code changes made when per-material Freestyle line colors were introduced
in rB7915d7277ac8c605f016f30f943080556244fb59. In 2.71 line style
Material color/alpha/thickness modifiers was retrieving alpha transparency
from Material.alpha, whereas in 2.72 Material.line_color[3] was referenced.
The present fix reverts the aforementioned code changes.
This issue is a regression from 2.71, so the fix is appropriate for inclusion in
the 2.72a release.
The following two sort keys are added for sorting chains.
* Projected X - Sort by the projected X value in the image coordinate system.
* Projected Y - Sort by the projected Y value in the image coordinate system.
A new line style option for the selection of first N chains is also added.
Moreover, the chain sorting and chain selection operations are now executed
in this order instead of the reverse order used previously. The UI has also
changed accordingly. This functional change is backward compatible and
won't result in visual differences.
Changes to ED_node_shader_default() were reverted since the code there was actually
not suitable for setting up the default line style node tree properly.
New properties 'line_color' and 'line_priority' are added to Material ID data blocks.
The 'line_color' property allows users to specify a per-material line color that can be
used as a Freestyle line color through Material color modifiers of line style settings.
The new line color property is intended to provide a solution for line color
stylization when a proper Freestyle support for Cycles is implemented (likely
as part of the upcoming Blender 2.72 release; see Patch D632). Materials in
Cycles are usually set up using shader nodes, and Freestyle won't be capable
of retrieving colors and other properties from node-based materials any soon.
The new line color property of materials addresses this foreseen limitation by
providing artists with an intuitive alternative mean to specify line colors on a
per-material basis independently from node trees.
The 'line_priority' property gives users a way to control line colors at material
boundaries. When a line is drawn along a feature edge at material boundaries,
one of the two materials on both sides of the edge has to be picked up to
determine the line color. So far there was no way to control this selection
(which was in effect at random). Now the material with a higher line color
priority will be selected.
The new per-material line settings are shown in the new Freestyle Line tab in
the Material context of the Properties window (only when Freestyle is enabled).
Line styles now have a set of new options for rearranging the stacking order of lines.
This gives artists more control to determine which lines should be drawn on top of others.
Two available sort keys are the distance from camera and curvilinear 2D length.
Since the distance of a line from camera may vary over vertices, another option called
integration type is used to compute the sort key for a line from the values computed at
individual vertices. Available integration types are MEAN, MIN, MAX, FIRST and LAST
(see the tool tips for more detail).
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.

- The "Same Object" chaining option enabled (see follow-up discussions in Bug #36629).
- Sphere radius set to 0.1 (was 1.0 resulting in a longer computation time).
- update copying code for linestyles to copy gaps
- update copying code for freestyle line modifiers to copy mapping flags and seeds
- fix drawing code for Material modifiers after a recent refactoring
and RNA for it independent of the build flag for enabling Freestyle. Suggested
by Sergey Sharybin through a code review of the branch.
* Many #ifdef WITH_FREESTYLE blocks were removed to always have Freestyle-specific
DNA file specification and RNA for it built in Blender. This will allow Freestyle
setting survive even when a non-Freestyle build is used for loading and saving
files. It is noted that operations are still conditionally built through #ifdef
WITH_FREESTYLE blocks.
* To this end, new blenkernel files BKE_freestyle.h and intern/freestyle.c have
been added. All API functions in FRS_freestyle_config.h as well as some of those
in FRS_freestyle.h were moved to the new files. Now the relocated API functions
have BKE_ prefix instead of FRS_.
* Removed the checks of NULL pointers after malloc/calloc.
* Replaced repeated cast operations with a temporary variable initialized with one cast operation.
* Removed an unused switch block (meant to be a place to put per-modifier resource management code).
Resolved conflicts:
release/datafiles/startup.blend
source/blender/editors/space_nla/nla_buttons.c
Also updated source/blender/blenkernel/intern/linestyle.c as a follow-up of
recent changes for the use of bool.
* Split and moved Cycles’ render layers panels into the render_layer
context as well (would be nice to hide this context when not needed,
e.g. with the BGE, but this is not so easy to do nicely...).
* Fixed some inconsistencies with trunk (probably due to svn merge
glitches) using r52858 as reference. Also recovered the missing
release/bin/blender-softwaregl file.
* A bunch of style code fixes in Blender's own code (not Freestyle
itself yet): line lengths, spaces around operators, block formatting,
headers, etc. In rna_linestyle.c, color_blend_items was replaced by
ramp_blend_items (exported from rna_material.c).
RNA subtype), since Freestyle internally use angles in radians.

NOTICE FOR BRANCH USERS:
This commit may break line drawing settings of already saved Freestyle files.
All angles are now treated as radians instead of degrees, so collections of
angle values might be necessary in order to recover previous visual results.
Affected properties are:
- Crease Angle in the edge detection options
- Min 2D Angle in the 'Splitting' section of a line style
- Max 2D Angle in the 'Splitting' section of a line style
- 'orientation' parameter of the Calligraphy thickness modifier
- 'angle' parameter of the PerlinNoise1D geometry modifier
- 'angle' parameter of the PerlinNoise2D geometry modifier
- 'angle' parameter of the 2DTransform geometry modifier

Additional changes:
* Fix for recent changes of BKE_* function renaming.
* Fix for an "attempt to free NULL pointer" in BlenderStrokeRenderer::RenderStrokeRepBasic().
The new options enable a better control on the position of stroke thickness with
respect to stroke backbone geometry. Three predefined positions are:
* center: thickness is evenly split to the left and right side of the stroke geometry.
* inside: strokes are drawn within object boundary.
* outside: strokes are drawn outside the object boundary.
Another option called "relative" allows users to specify the relative position by a
number between 0 (inside) and 1 (outside).
The thickness position options are applied only to strokes of the edge types SILHOUETTE
and BORDER, since these are the only edge types defined in terms of object boundary.
Strokes of other edge types are always using the "center" option.
* Added a new chain splitting option for dividing chains into pieces having
a given curvilinear 2D length.
* Rearranged the UI controls of chain splitting options according to the
actual order of processing.
* Made changes for converting each view edge into a chain in the case of
not using chaining.
