hunspell: Upgrade 1.7.5 -> 1.7.6

Upgrade to release 1.7.6:

- add, add_with_flags, add_with_affix and remove apply the
  dictionary's ICONV rules to the word, as spell does, so a
  caller that converted the word itself must stop doing so
- A personal dictionary exclusion such as *afterwards also
  rejects the word when the dictionary has it only as an affixed
  form
- stem and analyze give st: stem fields again with
  COMPLEXPREFIXES
- analyze lists every analysis of a compound word, where a
  rejected split of the word could hide the splits after it
- The text and XML parsers check the character after a character
  entity such as à
- The interactive mode shows the first digit of a two digit
  suggestion number
- The -a pipe interface checks a line of any length in one piece
- The hunspell tool takes -- as the end of the options, the -u2
  sed script escapes the word and the suggestion, and a zipped
  ODF file whose name starts with - can be checked
- The hunspell tool no longer searches the OpenOffice.org 2.x and
  3 folders or LibreOffice's user wordbook folder for
  dictionaries, and searches /Library/Spelling and
  ~/Library/Spelling only on macOS
- On Windows, search the share\hunspell, share\myspell and
  share\myspell\dicts folders of the installation that holds
  hunspell.exe
- New configure option --disable-tools to build and install only
  the library
- A static-only build records that in the installed hunvisapi.h,
  so its users need not define HUNSPELL_STATIC
- Install the Hungarian hunspell.5 in hu/man5
- Use Mozilla's own FileMgr and csutil code in MOZILLA_CLIENT
  builds
- A CMake build of the library, as an alternative to configure
- New configure option --enable-werror, off by default
- Man page: the fallback dictionary is en_US, the SYNOPSIS lists
  -u, -U, -u2, -u3, -P and --trace, and -a reads a file with the
  pipe protocol too
- Build fixes: MinGW, the BSDs, macOS, makealias without gawk or
  GNU sed, readline and curses detection, and the release tarball
  ships the CMake files and all the test data
- oss-fuzz and Coverity fixes and hardening
