[Qemu-devel] [RFC][PATCH v2 07/17] qapi: qmp-gen.py, use basename of path for guard/core prefix

[Michael Roth]

To avoid errors when generating output to a seperate subdirectory, use
only the filename, minus any leading directories, when passing it into
functions to be used as a prefix for header guards, includes, etc.

Also, trim file extensions based on "." seperator instead of assuming a
single-char extension and trimming the last 2 chars
