To lower the entry level for new developers, add a link to the 9p
developer docs (i.e. qemu wiki) to MAINTAINERS and to the beginning of
9p source files, that is to: https://wiki.qemu.org/Documentation/9p

The "local" tests can fail on some automated build systems as
reported here:
https://lists.nongnu.org/archive/html/qemu-devel/2020-11/msg05510.html
This will need to be investigated and addressed later. Let's go for a
workaround in the meantime : mark the "local" tests as "slow" so that
they aren't executed with a simple "make check" like in the case above.

Split out walking a directory path to a separate new utility function
do_walk() and use that function in do_mkdir().
The code difference saved this way is not much, but we'll use that new
do_walk() function in the upcoming patches, so it will avoid quite
some code duplication after all.

Use mkdtemp() to generate a unique directory for the 9p 'local' tests.
This fixes occasional 9p test failures when running 'make check -jN' if
QEMU was compiled for multiple target architectures, because the individual
architecture's test suites would run in parallel and interfere with each
other's data as the test directory was previously hard coded and hence the
same directory was used by all of them simultaniously.
This also requires a change how the test directory is created and deleted:
As the test path is now randomized and virtio_9p_register_nodes() being
called in a somewhat undeterministic way, that's no longer an appropriate
place to create and remove the test directory. Use a constructor and
destructor function for creating and removing the test directory instead.
Unfortunately libqos currently does not support setup/teardown callbacks
to handle this more cleanly.
The constructor functions needs to be in virtio-9p-test.c, not in
virtio-9p.c, because in the latter location it would cause all apps that
link to libqos (i.e. entirely unrelated test suites) to create a 9pfs
test directory as well, which would even break other test suites.

This test case uses the 9pfs 'local' driver to create a directory
and then checks if the expected directory was actually created
(as real directory) on host side.
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.

This patch introduces 9pfs test cases using the 9pfs 'local'
filesystem driver which reads/writes/creates/deletes real files
and directories.
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.

All existing 9pfs test cases are using the 'synth' fs driver so far, which
means they are not accessing real files, but a purely simulated (in RAM
only) file system.
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.

The previous, already existing 'basic' readdir test simply used a
'count' parameter big enough to retrieve all directory entries with a
single Treaddir request.
In the 3 new 'split' readdir tests added by this patch, directory
entries are retrieved, split over several Treaddir requests by picking
small 'count' parameters which force the server to truncate the
response. So the test client sends as many Treaddir requests as
necessary to get all directory entries.
The following 3 new tests are added (executed in this sequence):
1. Split readdir test with count=512
2. Split readdir test with count=256
3. Split readdir test with count=128
This test case sequence is chosen because the smaller the 'count' value,
the higher the chance of errors in case of implementation bugs on server
side.

The first readdir test simply checks the amount of directory
entries returned by 9pfs server, according to the created amount
of virtual files on 9pfs synth driver side. Then the subsequent
readdir test also checks whether all directory entries have the
expected file names (as created on 9pfs synth driver side),
ignoring their precise order in result list though.

The 9p protocol sends strings in general without null termination
over the wire. However for future use of this functions it is
beneficial for the delivered string to be null terminated though
for being able to use the string with standard C functions which
often rely on strings being null terminated.
