Let's make this clear by changing the prefix of the individual qtest case names from 'fs/' to 'synth/'. That way they'll be easily distinguishable from upcoming new 9pfs test cases supposed to be using a different fs driver.

In this initial version, there is only one local test which actually only checks if the 9pfs 'local' device was created successfully. Before the 9pfs 'local' tests are run, a test directory 'qtest-9p-local' is created (with world rwx permissions) under the current working directory. At this point that test directory is not auto deleted yet.

For that reason simply delete the test directory (if any) before (re)creating it on test suite startup. Note: The preferable precise behaviour would be the test directory only being wiped once *before* a test suite run. Right now the test directory is also wiped at the *end* of a test suite run because libqos is calling the virtio_9p_register_nodes() callback for some reason also when a test suite completed. This is suboptimal as developers cannot immediately see what files and directories the 9pfs local tests created precisely after the test suite completed. But fortunately the test directory is not wiped if some test failed. So it is probably not worth it drilling another hole into libqos for this issue.

For instance by passing an empty string it would return the root path on host of the exported 9pfs tree.

This patch introduces a custom split() implementation, because the test code requires non empty array elements as result. For that reason g_strsplit() would not be a good alternative, as it would require additional filter code for reshuffling the array, and the resulting code would be even more complex than this split() function.
