add loongarch64 architecture support - #286

…3nks

mrjimenez flagged on PR amule-project#514 review that these three contributors
were missing from the roster:

* Werner Mahr / Vollstrecker — has merge access on amule-project/amule
  and merges incoming PRs (e.g. amule-project#430, amule-project#385, amule-project#319, amule-project#330, amule-project#286). Goes
  under Maintainers based on that role.
* Pablo Barciela / Sc0w — recent contributor, e.g. wxWidgets 3.2.6
  build fixes, GTK version-check cleanup, dropping gtk1/gtk2 support,
  Chinese translation work. Goes under Developers.
* got3nks — Wayland app_id binding + SNI tray (amule-project#508), macOS UX
  (amule-project#508), libmaxminddb CI fix (amule-project#507), ip2country/upnp/nls/boost
  hard-fail series (amule-project#509/amule-project#511/amule-project#512/amule-project#513), packaging (amule-project#510),
  docs modernize (this PR). Goes under Developers.

Other recent folks may be missing too — those can be added in
follow-up commits as they're identified. mrjimenez explicitly noted
this is the priority subset to not block the rename PR.

Add a user-configurable filter that keeps files out of the shared set by
name. Patterns are either a '|'-separated list of wildcards (default) or a
single regular expression, selected by a per-config flag so the two
interpretations never collide.

Core:
- CShareExcludeFilter compiles the pattern string once (wxMatchWild globs
  or one wxRegEx), case-insensitive in both modes. An empty pattern or a
  regex that fails to compile yields an inactive filter -- a bad pattern
  fails open (shares everything) rather than excluding all.
- CSharedFileList::AddPathToShares bails before the stat/hash work when a
  name matches, so excluded files cost only a name test. The same chokepoint
  serves the bulk reload and the fs-watcher, so both agree.
- The per-reload excluded count is logged ("Excluded N files ...").

Prefs + EC:
- /eMule/ExcludeSharePatterns + /eMule/ExcludeSharePatternsUseRegex, synced
  to amuled over EC (EC_TAG_DIRECTORIES_EXCLUDE_PATTERNS/_REGEX); a remote
  change recompiles and rescans without a daemon restart.

UI (Directories panel):
- Pattern field + "patterns are regular expressions" checkbox (both work in
  the remote GUI and sync over EC).
- A "Preview" button reports how many currently-shared files the typed
  pattern would exclude. It reads the core's in-memory shared list, so it is
  compiled out of the remote GUI (CLIENT_GUI).
- On apply, an invalid regex is reported and the filter left disabled.
