Add support for options file inclusion
New include-path prefixes, c++: and cli:, are now recognized (e.g.,
include <cli:foo>;). Without a prefix, the include declarations is
considered to be c++-include unless the path ends with the .cli
extension.
The cli-included files are loaded and parsed. Currently, only inclusion
relative to the current file is supported. Duplicate inclusions are
detected and ignored based on the absolute filesystem path.
If a file cli-includes another file, then the runtime code is assumed
to come from the included file and is not generated.
