* [KMTEST] Initial usermode support for testing FS mini-filters
- Add base routines to wrap the win32 'Filter' APis
- Add support routines to be used when testing FS filter drivers
- Move KmtCreateService to a private routine so it can be shared with KmtFltCreateService
- Completely untested at the mo, so likely contains bugs at this point
[FLTMGR]
- Partially implement registering contexts
- Add a misc file which contains stubs of the APIs needed in the test suite
- Export some APIs needed by the test suite
[KMTESTS]
- Create a File System Mini-filter wrapper to host drivers for the filter manager tests
- Add a test file which will be used for testing that mini-filters load correctly
- Add a test file which will be used to write tests for IRP_MJ_CREATE requests
