Jan Tojnar 35d24b51f5 makeHardcodeGsettingsPatch: Rename from glib.mkHardcodeGsettingsPatch
glib expression is messy enough as is.

Also rename the `glib-schema-to-var` argument to `schemaIdToVariableMapping` to better match Nixpkgs coding style.

/*
Can be used as part of an update script to automatically create a patch
hardcoding the path of all GSettings schemas in C code.
For example:
passthru = {
hardcodeGsettingsPatch = makeHardcodeGsettingsPatch {
inherit src;
schemaIdToVariableMapping = {
...
};
};
updateScript =
let
updateSource = ...;
updatePatch = _experimental-update-script-combinators.copyAttrOutputToFile "evolution-ews.hardcodeGsettingsPatch" ./hardcode-gsettings.patch;
in
_experimental-update-script-combinators.sequence [
updateSource
updatePatch
];
};
}
takes as input a mapping from schema path to variable name.
For example `{ "org.gnome.evolution" = "EVOLUTION_SCHEMA_PATH"; }`
hardcodes looking for `org.gnome.evolution` into `@EVOLUTION_SCHEMA_PATH@`.
All schemas must be listed.
