This is a large changeset that changes the way we store package
remote info. In these changes, package remotes are entirely
encoded in a single URL. This will help reduce complexity
down the road when multiple different remote types are supported.

The kind of a remote is specified by the URL's scheme, and the
URL parsing differs based on the scheme. For now, only git+http
and git+https are supported.

This comes along with a change to the format of the catalog JSON.
Remote information is now entirely encoded in a URL string.

Also, run all tests in a path with cyrillic chars and spaces

This is a very rudimentary version. All it does is copy and rename the
template header file and place it in the build directory in a special
subdirectory that is added as an #include-path.

There is some code duplication and cleanup necessary. There are a
few "magic strings" and "magic paths" that need to be removed as well.
