eldritch horrors 67f1aafd61 libstore: restrict curl protocols
previously it was possible to fetchurl a dict server, or an ldap server,
or an imap server. this is a bit of a problem, both because rare schemes
may not be available on all systems, and because some schemes (e.g. scp)
are inherently insecure in potentially surprising ways we needn't allow.

transfers no longer allow arbitrary url schemas Breaking Changes

horrors

Lix no longer allows transfers using arbitrary url schemas. Only http://, https://, ftp://, ftps://, and file:// urls are supported going forward. This affects builtins.fetchurl, <nix/fetchurl.nix>, transfers to and from binary caches, and all other uses of the internal file transfer code. Flake inputs using multi-protocol schemas (e.g. git+ssh) are not affected as those use external utilities to transfer data.

The s3:// scheme is not affected at all by this change and continues to work if S3 support is built into Lix.
