gnu: icecat: Support Guix packaged extensions and native manifests.
* gnu/build/icecat-extension.scm: New file with a MAKE-ICECAT-EXTENSION procedure that makes sure the add-on directory is a symlink, so that Icecat can normalize it into a package store path. * gnu/local.mk (dist_patch_DATA): Register it, as well as new patches. * gnu/packages/browser-extensions.scm (ublock-origin)[properties]: Store the add-on ID so that it is accessible in MAKE-ICECAT-EXTENSION. [arguments]: Use the add-on ID as root directory. (ublock-origin/icecat): New procedure. * gnu/packages/gnuzilla.scm (icecat-minimal)[arguments]: Rewrite the unused 'apply-guix-specific-patches' phase so that it applies the following two patches. [native-search-paths]: New field. * gnu/packages/patches/icecat-compare-paths.patch: New patch that compares add-on paths (which are package store paths) to detect package changes. * gnu/packages/patches/icecat-use-system-wide-dir.patch: New patch that replaces "/usr/lib/mozilla" (the system-wide directory for extensions and native manifests) with "$ICECAT_SYSTEM_DIR".
