Also remove historic bftgl reference.

Functions that utilize glyph cache should lock and unlock cache by
calling `blf_glyph_cache_acquire()` and `blf_glyph_cache_release()`.
Function `blf_glyph_cache_acquire()` will create glyph cache, if it doesn't exist.
Locking mutex is global and shared by all fonts.

Some statements were split across multiple lines because of their
trailing comments.
In most cases it's clearer to put the comments above.

We cannot reliably use translations API from non-main threads.
Now storing translated strings in a static cache, with basic mechanism
to update it on language change.

We were missing a null pointer check for invalid fonts.

Avoid BLF having to be concerned with decoding the string
(which can fail).
Also remove redundant extra zero byte from strings.

Use doxy references to function and enums,
also correct some names which became out of sync.

We do not support special color fonts (like colored emoji fonts), so
don't crash when trying to create a preview for unsupported fonts.

There are two issues at play here.
First, BLF_width computed a width that was not wide
enough to actually hold the text.
Second, blf_glyph_calc_rect_test computed an incorrect
rect->xmax when the glyph was moved to the left a bit.
We ignore the overlap on the left, but the right side
should still be adjusted accordingly.

The main problem was that the character `J` has "negative kerning".
It was cut off because it started outside of the clipping rectangle.

While \file doesn't need an argument, it can't have another doxy
command after it.

Move \ingroup onto same line to be more compact and
make it clear the file is in the group.

BF-admins agree to remove header information that isn't useful,
to reduce noise.
- BEGIN/END license blocks
Developers should add non license comments as separate comment blocks.
No need for separator text.
- Contributors
This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.

`to_strlen` just benefits from using pre-computed kerning table for
ascii chars (gives about 30% speed improvements).
`to_rstrlen` was re-written and heavily simplified, basically using same
logic as `to_strlen`, and `BLI_str_find_prev_char_utf8()` to loop
backward in the string, instead of looping forwards the whole string,
storing each gliph's width in temp array, and looping backward on that
temp array to find final string matching expected width. Gives about 70%
speed improvements!
And both functions can now share their core logic.

This changes the text hinting setting to be an enum with options
Auto / None / Slight / Full. The default is Auto which currently disables
hinting.
The hinting was tested with a new FreeType version, but this is not what
is used on the buildbots an official release environment, and the fonts
look quite bad because of that. Once FreeType has been upgraded we can
change the default.
Even then the results are not ideal, perhaps due to missing subpixel
positioning and linear color blending support in BLF.

Now disabling anti-aliasing doesn't impact sequencer, render stamp etc.
|
|
GPU_LINEAR is there for shadow font blurring, the real issue was lack of
rounding for the batch offset.
|
|
Barely any visible difference, except when drawing big custom text
with the Python API.

This does not include all the struct and type renaming. Only files were
renamed.
gwn_batch.c/h was fusioned with GPU_batch.c/h
gwn_immediate.c/h was fusioned with GPU_immediate.c/h
gwn_imm_util.c/h was fusioned with GPU_immediate_util.c/h

- Texture creation now requires explicit data type.
- GPU_texture_add_mipmap enable explicit mipmap upload.
- GPU_texture_get_mipmap_size can be used to get the size of a mipmap level
of an existing GPUTexture
- GPU_texture_read let you read back data from a gpu texture.

BLF' blf_font_width_to_strlen() could easily generate strings with up to
nearly two pixels length over requested limit!
Note that the fiddling between floats and ints values make things really
confusing here... :/
There is still a few limit cases where, even though computed str length
is now always below reauested limit, we still get first letter
disappearing, no idea why currently.
