Fix T46524: Use Alpha (Straight/Premultiply) option missing in 2.76 for DDS files.

All optional image format are not #define'd in submodules like DDS read/write code.
This means values of `eImbTypes` would not always be the same in all contexts, yuck!

This is a regression and should be backported to 'a' release.

Mesh remapping: fix loop 'best matching normals' not using transform space.

Also, cleanup, reduce declarations of tmp_co/_no...

Fix T46429: Movie clip is deformed by resolution multiplier when offset is added in sequence editor.

Fix T46508: data_transfer of normals fails in case objects are transformed.

The final stage of the process (copying/interpolating new dst cddata from src cddata)
was simply broken in normal case, where we need to convert from source to destination
object space.

This patch is a bit verbose, but I cannot see how to avoid it really.

To think this code is in master since over 6 months and it only gets reported now... :/

Fix broken CD_NORMAL interpolation callback (would generate non-unit vectors).

Even if the weights are normalized, the weighted sum of normalized vectors
usually does **not** give a normalized vector (unless all source vectors
are aligned).

This probably was not a big issue in most cases, since we usually interpolate
similar vectors here - but still!

error in last commit

Fix for missing id_lib_extern, assigning ID's

Fix T46502: Linked dupli-group lost on reload

Fix T46493: Wrong camera zoom blur with non-unit pixel aspect

Fix T46465: Lag scrubbing w/ PlayAnim

Fix T46494: Can't de-select a face w/ mixed modes

Fix crash pressing +/- in file-selector

Filenames over 128 chars would crash.
Move BLI_newname into file_ops,
this was only used in one place and isn't all that re-usable.
Also remove special behavior for 4 digits.

Fix T45900: Allow again white spaces in file names.

Should probably be added to 'a' release, should we do one...

Fix memory leaks in PlayAnim

Was never freeing filenames or pictures.

Fix T46503: Snap scale fails using corner pivot

Fix crash w/ PlayAnim & long filenames

Paths >128 chars could crash.
Replace BLI_newname with direct BLI_stringenc/dec use which makes more sense in this case.

PlayAnim: avoid list count setting frame from mouse

Fix T46223: multiview image sequences crashing.

Fix T46453: JPEG quality not stored in file

This is a feature unique to jpeg that would store the quality it was saved.

- Use struct instead of bit-shifting.
- No longer store the 'flag'.

Fix T46487: OpenSubdiv objects are invisible in Blender Internal "Rendered" viewport mode
