Failure to alllocate vertex buffer would not fall back to vertex array
properly.

This should fix failure to use vertex arrays in OSX with high
polycounts.

Note this will not suffice as a fix when we move to VBOs exclusively
(GL 3+), we'll have to think of some way to separate huge meshes to many
VBOs.

Fix: fixed UI description of Action.new() function

Math Lib: use vector funcs for isect_line_line_v2_point

Fix T45471: Blend file: Bad old_addr handling in mesh's customdata writing.

Issue is rather well explained in T45471: our current customdata writing code easily generates several different blocks in blend file with same 'old' address. This is bad, because those addresses are used as 'uid' during reading process (it kind of work in Blender's own reading process, by mere luck mostly, but breaks the file specs).

Solution (suggested by Campbell, thanks) implemented by this patch is to avoid duplicating everything, and instead just overwrite what we needs to skip some cdlayers on write:
* the CustomData's `totlayer` number;
* the CustomData's `layers` array of CustomDataLayer (keeping its original address using the `writestruct_at_address` helper).

New design allows us to get completely rid of the no_free flag stuff in `write_customdata()`.

Note that this implies written data is **not** directly valid from Blend PoV, since its written typemap does not match written layers (this is not an issue because typemap is rebuilt on read anyway - and it's easy to fix this if really needed).

Also, the backward compatibility saving of mface data remains an issue here, see comment in code.

Fix T45317: Cycles material preview unnecessarily re-rendering

The issue was caused by wrong fix for T22741 which forced redraws on any window
