* add rust-demangler
* drop deprecated rls
* drop unnecessary x86_64-unknown-linux-gnu stage 1 build
* force CI only pack tar.gz instead of both tar.gz and tar.xz
* further split subpackages into rust-std-*
* add subpackages rust-src, rustc-src
* add TERMUX_PKG_{BREAKS,REPLACES} on rust subpackages
termux_setup_rust might be run several times in a build recipe, so
that continued (`./build-packages.sh -c`) builds can be supported.
The setup function uses and then unsets CFLAGS, resulting in an error
the second time termux_setup_rust is run.
Make changes as per new design implemented in termux/termux-app@b950efec and termux/termux-app#2740
The package build and termux-tools scripts use current package manager for custom logic. The `termux-tools/termux-setup-package-manager` script has been added that will now be used to provide backward compatibility for termux-app `< 0.119.0` (when its released) and validate the package manager. It will also ensure the variable in not unset to prevent `unbound variable` errors if `set -u` is being used by calling scripts.

should not accept arbitrary values for marking them "enabled". Instead
they should accept boolean values which makes them easier to handle and
also makes their meaning clear.
build-package.sh should make decision based on variable's value but not on
whether it is set or empty.
%ci:no-build
Partial compatibility for on-device builds.
There is no guarantee that it will be possible to build all available
packages and built packages will have same reliability that cross-compiled
but should solve "self-hosting" problems as much as possible.
