Allow the user of libass to select the font provider from ass_set_fonts. This
API change actually doesn't break client code which was passing `fc=1`; now
the same value will autodetect a usable font provider.
Also add an api to list available font providers as that is useful for client
code to show drop down menus with a font provider to choose from.

Add wrapper to the ASS_Renderer to create a font provider from
its internal font selector and shuffle some code around to export
everything that's needed for font providers to the public. Document
font provider functions.

Pass the fontconfig configuration file option and enable switch
through into the font selector. This restores some of the old
functionality related to fontconfig.
However, the functionality to delay the fontconfig database update will
not come back. This is not a big problem. Later it will be possible to
manually add the fontconfig provider, which will delay the update in a
comparable way.

Implement a simple font sorter (FontSelector) and an interface to deal
with multiple font sources (FontProvider). Unfinished business,
but works for the most part. Currently the only implemented FontProvider
uses fontconfig.

Add tons of ASS_OVERRIDE_ flags, which control whether certain ASS_Style
fields are copied when doing selective style overrides with
ass_set_selective_style_override_enabled().
This comes with some cleanup. It should be fully backwards-compatible.

This adds 2 new API functions:
ass_set_selective_style_override()
ass_set_selective_style_override_enabled()
They can be used to force dialog text to use a specific ASS_Style. It
uses a fuzzy heuristic for that, and the quality of results may vary.
It does style overriding selectively and tries not to override things
that need explicit styling. The heuristic for that isn't set in stone
either, and can change with future libass versions.
Closes libass#88.

ass_set_aspect_ratio() is confusing, because it takes a DAR and SAR
value, while libass just needs a single pixel aspect ratio. Introduce
ass_set_pixel_aspect(), which sets the pixel aspect ratio directly.
ass_set_aspect_ratio() is considered deprecated. There's no reason to
remove it, but hopefully directing users to ass_set_pixel_aspect() will
make for a simpler API.
Improve the doxygen and document what ass_set_margins() actually does.

ass_set_storage_size() overwrote the user-defined aspect ratio set with
ass_set_aspect_ratio(). Change it so that if ass_set_aspect_ratio() is
used, the ass_set_storage_size() parameters are not used for any aspect
ratio calculations. (The storage size is still used for calculating the
blur scale.) This simplifies the code as well, because the aspect ratio
is now centrally calculated in ass_start_frame().
Update the doxygen. Make it clear that ass_set_storage_size() will be
used for aspect ratio calculation, unless ass_set_aspect_ratio() is
used. Also mention what libass actually does with the dar and sar
parameters: it uses them to calculate a pixel aspect ratio, nothing
else.
Explicitly allow resetting the storage size with w=h=0. Document that
it's allowed to remove the user defined aspect ratio by setting a pixel
aspedct ratio of 0.
See issue 6.

\blur radius is not scaled from script to storage resolution
but is scaled from storage to display resolution. The same
applies to borders and shadows if ScaledBorderAndShadow is "no".
(If it is "yes", borders and shadows are scaled from script
to display resolution just like before.)

This allows users to change the vertical position of normal subtitles.
MPlayer has such a feature as -sub-pos option using its internal
subtitle renderer.
Bump LIBASS_VERSION to indicate the API addition.

Now that it's possible to switch shapers at runtime, it also becomes a
lot easier to disable them at compile time. Add ifdefs and build system
changes so that HarfBuzz can be safely disabled. It's autodetected now
and enabled if available.
This shuffles a bit of code around, but there are no functional changes.
Note that FriBidi remains mandatory for the time being, but this
shouldn't pose any problems, since it is a small and very portable
library without any special dependencies.

Add an API call, ass_set_shaper, and infrastructure to make shapers
selectable at runtime. Currently, this allows to switch between two
shapers: a SIMPLE shaper that maps to FriBidi and a COMPLEX shaper that
maps to HarfBuzz.

Glyphs and drawings have wildly different hash keys. Subclass the hash
keys of glyphs and drawings in a new, unified outline cache. This also
fixes some issues with drawings in the glyph cache. Now, the textual
description of the drawing is included in the key (the hash value isn't
really good enough, especially not fnv32) and the baseline offset is
saved as well.

- less code, cleaner
- decoupled from ASS_Library
- better data encapsulation
- simpler interface
- avoids a nasty hack

In hope to make libass as useful as possible, relicense libass to ISC, a
simplified 2-clause BSD license. All contributors who provided
non-trivial changes have granted their permission for this.
