[bitbake-devel] [PATCH] fetch2/git.py: improve error reporting when an invalid protocol is used

[Scott Garman]

When an invalid 'protocol' parameter is used in a git SRC_URI,
the error reported was not helpful:

ERROR: Function 'Fetcher failure for URL: 'None'.
<environment dump>
fatal: Could not make temporary directory: No such file or directory

So instead check that ud.proto is set to something valid, and if not
raise a meaningful ParameterError which explains that the protocol
type is the source of the problem.

This fixes bug [YOCTO #1142]
