BLI_linklist_free() was incorrectly taking MEM_freeN() as an argument, evidentially this works on x86 - but could cause issues later on.
add BLI_linklist_freeN() which MEM_freeN's each item.

split up BKE_mesh_to_curve() into 2 functions, adding BKE_mesh_to_curve_ex() which doesn't do object type conversion.

converting a mesh to a curve was unnecessarily using tessface's.
use mpolys instead and simplify checks for wire edges.

Also rename BKE_mesh_from_curve() --> BKE_mesh_to_curve() since this function converts a mesh into a curve.

Userprefs:Addon panel - Renamed label of the link to the documentation

There was a regression in recent bugfix which touched Mix node.

This commit hopefully fixes that regression.

Fix misguiding menu label and make tooltip more descriptive

use floats for knife tool internal mouse coord.

Usual blenderplayer fix! :p

minor knife refactor to prepare for running non interactively.

disable -Wredundant-decls for gcc versions older then 4.6

ui_def_but() allocating an extra byte in 'but->str' for no reason.

use BLI_strncpy_rlen() rather then BLI_snprintf() when no formatting is needed.
also replace sprintf with strcpy when no formatting is done.

Code cleanup: replace magic constant used for alpha ignore flag with a define.

add BLI_strncpy_rlen(), a clone of BLI_strncpy() that returns the number of bytes copied.

also move doxy comments for BLI_string.h into the C file.

Fix #34616: Wrong face culling for curves with constructive modifiers

If curve object does have derived mesh, culling shall happen for
back faces, not front.

minor change to BLI_strncpy(). replace strlen() with BLI_strnlen().

code cleanup: de-duplicate view clipping function for paint and knife tool, minor changes to knife initialization.

Border rendering now works for all scenes used in compositor,
before this only active scene would be rendered with border.

When do_render_fields_blur_3d() is finished, it'll modify
render's display rect so it'll correspond bordered render
result placed on black backgrund. Actual border is stored
nowhere, which makes it only way to re-calculate disprect
for all other renders used in compo based on source. Not
so big deal actually.

Also needed to modify Cycles a bit, because before this
patch it used border settings from scene being rendered.
Now made it so render data is passing to external engines.

Using a property inside RenderEngine structure for this.
Not best ever design for passing render data, but this
would prevent API breakage. So now external engines could
access engine.render to access active rendering settings.

tweaks to clang so blender can build with -Werror

Quick fixes for previous commit
* Missing word in tooltip for operator
* Ensure that filters are set appropriately so that effect is visible
