mupdf: add recipe for version 1.10~a. (#1121)

* Mark 1.10~a as broken since there are still a few issues:
    - libmupdf.so is not being built.
    - libmupdfthird.a is being built but is empty.
    - unlike 1.8, 1.10~a cannot be built on x88_gcc2 primary
      arch because a dependency on harfbuzz was added. That
      said, it might be possible to remove that dependency.
* Updated patches from 1.8 to 1.10~a.
* Added patches to fix includes for hb.h and hb-ft.h and to
  skip unneeded workaround in source/fitz/load-jpx.c
* Merged/replaced old patch with one from @korli.
* Add dependency on libharfbuzz and libglib_2.0 too, as it is
  required by harfbuzz.
