libass: update to 0.13.4

changes from 0.13.1 to 0.13.4

    Bug fixes found with fuzzing
    Fix memory reallocation in the shaper. (CVE-2016-7972)
    Fix two small memory leaks in the parser and test program.
    Fix illegal read in Gaussian blur coefficient calculations. (CVE-2016-7970)
    Fix mode 0/3 line wrapping equalization in specific cases which could result \ 
in illegal reads while laying out and shaping text. (CVE-2016-7969)

    Improve compatibility/portablility of build system, should fix e.g. \ 
compilation on Solaris.
    Fix memory leak in DirectWrite font provider.
    Fix the rasterizer when rendering some large outlines.
    Remove hack that forced RTL base direction depending on font encoding.
    Greatly improve the internal caches with refcounting and gradual clearing.

    Add ass_set_check_readorder() API function to disable use of the ReadOrder \ 
field for duplicate checking in ass_process_chunk().
    ass_step_sub(track, now, 0) now finds the start of the subtitle at now.
    Bug fixes:
        Fix an issue with the new duplicate checking, which could lead to \ 
missing subtitles after seeking.
        Fix a crash with Core Text under specific circumstances.

Log message:
Release 0.13.1:
Much faster duplicate event check in ass_process_chunk. This can bring a large \ 
speedup for embedded subtitles with lots of events. To make this possible, it is \ 
now forbidden to combine calls to ass_process_chunk with any other method of \ 
manipulating the event list, namely, manual manipulation and calls to \ 
ass_process_data, ass_read_memory and ass_read_file.
Interpret negative timestamp components as actual negative numbers. This change \ 
increases compatibility with VSFilter.
Font matching changes for VSFilter compatibility
Look up fonts that contain PostScript outlines by their PostScript name instead \ 
of their full names. Family names continue to be used for all fonts.
Keep spaces in font names
Drop support for Fontconfig < 2.10.92 to ensure correct font matching
Bug fixes
Fix building the assembler code for the x32 ABI
Fix static linking against libass through pkg-config when libass uses libiconv
Fix some small memory leaks, potential crashes and bad data uses
