Cleanup: --help text output

Some arguments missed their <value>.

Cleanup: blf internal struct naming

- use x/y/width/height/max as a suffix.
- replace 'num' prefix /w 'len' suffix.

Cleanup: BLF batch drawing naming

- batching -> batch_draw.
- ct & size -> len.
- start/end -> begin/end (follow GL convention).

Logging: add ability to exclude categories.

Docs: doxygen docs for clog

Fix clog: own error allocating from static buffer

Fix logger build w/ MSVC

Build deps: do sndfile patch also on linux platform

GWN: Perf: Bypass glUseProgram(0)

I left a flag to quickly debug if something is wrong.
But now that everything uses shader, it seems to be alright since a shader
is always set active before drawing.

UI: Perf: Do not use implicit Attrib fill.

BFL: Fix broken vertical texts.

I've made a separate version of the geom shader that works with full
3D modelviewmat.

This commit also includes some fixup inside blf_batching_start().

DRW: Add BLF_batch_reset to be able to use BLF inside DRW.

UI: Perf: Add BLF batching for File browser and UI blocks.

This batch together most of the calls that can be batch together.

BLF: Add Batching capabilities.

You can now use BLF_batching_start and BLF_batching_end to batch every
drawcall to BLF together minimizing the overhead introduced by BLF and the
opengl driver.

These calls cannot be nested (for now).

If the modelview matrix changes, previously batched calls are issued and a
the process resume with the new matrix.

However the projection matrix MUST not change and gl scissors as well.

GPUFramebuffer: Fix assert triggering another assert.

BLF: Use Batch API instead of IMM.

This is not a perfect win just yet. It's now calling glBufferSubData for
every call (instead of using glMapBufferRange which is almost faster), but
with this system we will be able to batch drawcalls together.

See next commit.

GWN: Add GWN_vertbuf_vertex_count_set.

This allows us to specify a the number of vertices to upload to the gpu.
This is to keep the same allocation on the System Memory but send the least
amount of data to the GPU/Driver.

C Logging: use instead of printf for messages

- See `--log` help message for usage.
- Supports enabling categories.
- Color severity.
- Optionally logs to a file.
- Currently use to replace printf calls in wm module.

See D3120 for details.

build_deps: Disable building docs for OIIO

Two issues are fixed with this commit:

1) When we build OIIO (on unixoid build environments) and no /src/doc/oiiotool was present we had no build target for it (which led to a build error). As we don't need docs for OIIO, we disable it now.

2) We specified a var that OIIO does not recognize (was removed upstream a long time ago): ILMBASE_VERSION.

Select Grouped: Collection Part II

Selecting not only the objetcs directly linked to the selected collection.
So we also do it for the objetcs in the nested collections, just as we can
do from the outliner.
