* gnu/packages/gnuzilla.scm (all-mozilla-locales)
(%icecat-version, %icecat-build-id): Update.
(icecat-source): Update upstream source hash.  Update to latest
gnuzilla commit.  Remove the code that previously applied
"icecat-use-older-reveal-hidden-html.patch".
(icecat)[inputs]: Use icu4c-71.
[native-inputs]: Use rust-1.59.  Use the default llvm and clang.
[arguments]: Add "--without-wasm-sandboxed-libraries" to the configure
flags.  Add 'remove-cargo-frozen-flag' phase.  In the 'configure'
phase, set the "MACH_BUILD_PYTHON_NATIVE_PACKAGE_SOURCE",
"GUIX_PYTHONPATH", and "MOZBUILD_STATE_PATH" environment variables.
Remove the code that previously set the "MACH_USE_SYSTEM_PYTHON" and
"MOZ_NOSPAM" environment variables.  In the 'install-desktop-entry'
phase, add "StartupWMClass=Navigator" to the desktop file.
[description]: "IceCat 91" --> "IceCat 102".
(all-mozilla-91-locales, %icecat-91-version, icecat-91-source): New
variables bound to the old values, for use by icedove.
(icedove)[source]: Ues 'icecat-91-source'.
