Fixed reflections on bvh tree
(its kinda of a hackish-fix.. must be improved later)

Merge from 2.5 rev 20515 through 20647.

MSVC cries of uninitialized param

PyRNA
- Support for python to convert a PyObject into a collection (uses a list of dicts - quite verbose :/)
- Operators can now take collection args when called from python.
- Support for printing operators that use collections (macro recording).
- Added RNA_pointer_as_string which prints all pointer prop values as a python dict.

Example that can run in the in test.py (F7 key)
bpy.ops.VIEW3D_OT_select_lasso(path=[{"loc":(0, 0), "time":0}, {"loc":(1000, 0), "time":0}, {"loc":(1000, 1000), "time":0}], type='SELECT')

for some reason lasso locations always print as 0,0. Need to look into why this is.

NLA SoC: NLA-Evaluation Bugfixes

* Fixed an evil bug where the last frame of a strip was always incorrectly evaluated.
This was because these frames were not being included in the strip's 'range' as defined by the IN_RANGE() testing macro, which only considers the given range as an open interval (i.e. non-inclusive of boundary points). I've added a new macro, IN_RANGE_INCL(), which is inclusive of boundary points, since this is a common test in many other parts of the code.

* When an AnimData block is in 'tweaking' mode, the tracks following (and including the active track) are now correctly skipped during evaluation.

* Finished coding the option of setting a single NLA-track per NLA-block to play 'solo' (i.e. only that track is enabled for evaluation).
To enable this, simply click on one of the grey 'dots' beside the NLA-track names, turning this dot yellow. The 'yellow' dot means that the track will play by itself (even the 'active action' gets silenced). Only one track per AnimData block can play solo at a time. To disable, simply click on the 'yellow' dot again.
NOTE: this currently uses the View3D layer-status icons. We probably need some special ones for these later (coloured vs grey star?)

* Also (not related to evaluation) made the selection operators for the NLA Editor only work when not in tweaking mode, since in tweaking mode they can potentially result in data being resolved inappropriately when leaving tweaking mode.

NLA SoC: Operators for 'tweaking' strip actions (TAB-Key for both)

In this commit, I've introduced the mechanism by which actions already referenced by strips used in the NLA can be edited (or 'tweaked'). To use, simply select a strip you wish to edit, and hit that TAB key to start tweaking that strip's action, and hit TAB again once you're done.


What happens when you enter 'tweak mode':
1) The action of the active strip temporarily becomes the 'active action' of the AnimData block. You are now able to edit this in one of the Animation Editors (DopeSheet/Action, Graph Editors) as per normal (i.e. sliding keyframes around, inserting keyframes, etc.). The 'action-line' will therefore get drawn immediately above the active track containing the active strip, so that it's clear that that's what we're editing.

2) All the NLA-tracks (and all the strips within them) that occur after the track that the active strip lived in get disabled while you're in tweakmode. This is equivalent to travelling back to an earlier state in a construction history stack.

3) The active NLA track also gets disabled while in tweakmode, since it would otherwise interfere with the correct functioning of the tweaking for the action of interest.

4) The 'real' active action (i.e. the one displaced by the active strip's action) gets put into temp storage, and will be restored after you exit tweakmode.

5) Any strips which also reference the action being tweaked will get highlighted in red shading to indicate that you may be making some changes to the action which you don't really want to make for the other users too.


Please note though, that this is only a rough prototype of this functionality, with some niceties still to come. i.e.:
* NLA-tracks after the active track should still get drawn above the 'tweaking action line', but perhaps with different appearance?
* Various tools will still need awareness of this to prevent corrupting operations from taking place. How to proceed is still undecided...
* When exiting tweak-mode, the strip the action came from still needs some form of syncing with the modified action... there are a few tricky issues here that will need to be solved
* Evaluation code doesn't totally take this into account yet...

Also, fixed a number of bugs with various code (notably selection, and also a few drawing bugs)

coverity issues:

again moved assignment after check to make sure pointer is valid.

No need to copy the memory if the pointer isn't valid.

again moving init code after check to valid pointer.

getScreenPosition, Ray and Vect fixes:

- fix for [#18867] getScreenRay error
... the Vector wasn't been added to KX_Camera origin. Therefore the Ray was always casted to the wrong coordinate when camera wasn't in [0,0,0] (where is obviously was in my tests :)

- making the input parameter compatible with Blender/BGE window coordinate system (Top-Bottom).
... that will break scripts done in 2.49. Since this feature was added only in 2.49 that fix is OK. (and the fix is ridiculous.

Note:
the input parameter is normalized. That means it runs from 0.0 to 1.0. Some users found it confusing, but it allows to make a game compatible with multiple desktop resolutions.a

UI:
* Make ESC-key close the search popup menu.
* Also make ESC-key cancel number button dragging.

BGE [#18884] light in skinned object only work properly after running the action once.

2.5 filebrowser
* code cleanup: removed unused fileselect mode (type)
* brought back 'hide dot files', needs proper storing of the settings still.

2.5 MSVC projectfiles
* added file editors/space_buttons/buttons_context.c
* removed BRE_yafray project

2.5

Just a minor tweak in menu draw, makes Search menu a tinsy prettier.
Tomorrow more!

iTaSC: substep evaluation. Max delta joint measured on the whole interval and not just the last substep during initial iteration. Substep computed as whole fraction of timestep for more stability.

coverity issue CID: 488
Checker: REVERSE_INULL (help)
File: base/src/source/blender/src/hddaudio.c
Function: sound_hdaudio_extract_small_block
Description: Pointer "hdaudio" dereferenced before NULL check

Moved some init code that uses a pointer to after the check
to see if pointer is valid.

Bugfix

Loading font used a minimal string array (80 chars) and copied file name
strings in it without size checks. Triple tsk!

2.5

Bugfix: Icons were drawing on wrong subpixel positions, distorting
badly. Now it's crispy and tasty!

Noticed there's a magnifier icon already, using it for the search
option.
