Factorized writing of ID block's data (so far, only IDProps) into own helper func.
This also fixes missing IDProp (aka custom data) saving from GreasePencil and Library
datablocks (and add comment about why we do not save WM IDProps).
Finaly, it ensures all ID-related data are written immediately after the ID itself
(was not the case for all data types previously, some were writting their own data
before IDProps). This is not a fix (.blend file format does not enforce any order
on sub-data of datablocks, they only have to be after datablock struct itself in file),
but makes things more consistent.
Before the intervall was set to 0.125 which effectively resulted in 8 positions across the UV space (per axis).
I halved that value, holding shift enables an even finer movement.
This change was ported over from my soc-2016-uv_tools branch after talking with howardt, ideasman42 and hackerman-
When this flag is set - even when the curve error is under the threshold,
keep attempting a better fit.
Enable this for freehand drawing, since it gives nicer results and isn't noticeably slower.
Also, can use numeric input to set segments and profile when
in those respective value-adjusting modes (as per S or P toggle).
Finally, fixed problem with previous bevel commit: when changing
value-adjusting mode, would like to start off resumed value adjustment
where it was before.
Auto-merge caused all edges between selected vertices to be selected.
This only makes sense in vertex-select-mode.
Correct edge-flag merging code, which now merges flags from multiple edges.
Short story: draw_lamp would add itself to delayed transp drawing list from 'xray' drawing step.
This was broken, since delayed transp drawing list is always handled **before** delayed xray one.
After undo it lead to segfault crash, v3d->afterdraw_transp still having reference to old freed scene's base.
Also added asserts that those afterdraw list are empty at end of drawing step, should help
avoiding that kind of issue in future.

This improves on existing tangent calculation functions too.
- BM_face_calc_tangent_auto: Chooses method based on number of sides, used by manipulator (not exposed to Python).
- BM_face_calc_tangent_edge: from longest edge.
- BM_face_calc_tangent_edge_pair: from longest edge-pair (most useful with quads).
- BM_face_calc_tangent_edge_diagonal: edge farthest from any vertex.
- BM_face_calc_tangent_vert_diagonal: vert farthest from any vertex.
Also optimize BM_vert_tri_calc_tangent_edge* functions to avoid sqrt.
The purpose of the patch is to replace deprecated glShadeModel.
To decrease glShadeModel calls I've set GL_SMOOTH by default

Regression from recent rB2c5dc66d5effd4072f438afb, if last item of last chunk of a mempool was valid,
it would not be returned by mempool iterator step, which would always return NULL in that case.
It's still not completely working - there are still some glitches - but far better than before.
To make buttons of the uiList work, you have to add a 'check' callback to the operator that invokes the menu. Only if it returns True, the uiList gets refreshed. To avoid this we have to make the region refresh tagging in the entire button handling a bit smarter.
Changes I had to do:
* Call uiList handling from menu/popup handling if needed.
* Make uiList handling use special popup refresh tag if placed in menu.
* Allow popups invoked from py operator to tag for refresh by using operator 'check' callback.
* Tag popup for refresh when resizing uiList.
Mostly fixes T48612.
