libcaca-0.99.beta20-160000.2.2

- Drop pkgconfig(ftgl) BuildRequires: ftgl is unmaintained and
  libcaca does not actually link to it, despite configure checking
  for it and finding it. This was originally added to configure in
  2008 (commit 9752e82) to be used 'later'.

- Updated spec-file with manual optimizations.

- Added file libcaca-0.99.beta20-gcc14.patch (boo#1225795).

- Use %autosetup, prepare for RPM 4.20.
  * Rewrote patches so that they are applied uniformly via %autosetup.
  * Correctly reorder the patches in specfile declaration.

- add patch [libcaca-autoconf-2.69.patch]
  * Don't force autoconf to be at version 2.71

- Upgrade to 0.99.beta20
  * IPv6 support in cacaserver
  * fixed a bug from 2004 that caused PDF documentation generation to fail
  * memory allocation functions are now more robust
  * numerous fixes for memory leaks and invalid memory accesses:
  * CVE-2021-30498
  * CVE-2021-30499
  * CVE-2021-3410
  * CVE-2018-20546
  * CVE-2018-20547
  * CVE-2018-20545
  * CVE-2018-20548
  * CVE-2018-20549
- Dropped upstream fixed patches
  * libcaca-bsc1182731-prevent-overflow.patch
  * libcaca-variable-type.patch
  * Bug1120502-add_cast_to_prevent_overflow.patch

- When a zero-width or zero-height image is given, a divide-by-zero
  occurs. This patch checks for this and produces a zero-sized
  output.
  [bsc1197028-correctly-handle-zero-width-or-height-images.patch,
  CVE-2022-0856, bsc#1197028]

- The problem is due to the fact that the images in the POC have
  a size of 0x0 and thus, when exporting, no data is written for
  the image bits.
  However, space is allocated for the header only, not taking
  into account that sprintf appends a NUL byte.

- More overflow prevention of multiplying large ints
