The standard cluster descriptor in L2 table entries has a field to
store the host cluster offset. When we need to get that offset from an
entry we use L2E_OFFSET_MASK to ensure that we only use the bits that
belong to that field.
But while that mask is used every time we read from an L2 entry, it
is never used when we write to it. Due to the QCOW_MAX_CLUSTER_OFFSET
limit set in the cluster allocation code QEMU can never produce
offsets that don't fit in that field so any such offset would indicate
a bug in QEMU.
Compressed cluster descriptors contain two fields (host cluster offset
and size of the compressed data) and the situation with them is
similar. In this case the masks are not constant but are stored in the
csize_mask and cluster_offset_mask fields of BDRVQcow2State.

iotest 147 and 205 have recently been marked as "NBD-only", so they
are currently simply skipped and thus can be removed.
iotest 129 occasionally fails in the gitlab-CI, and according to Max,
there are some known issues with this test (see for example this URL:
https://lists.nongnu.org/archive/html/qemu-block/2019-06/msg00499.html ),
so for the time being, let's disable it until the problems are fixed.
The iotests 040, 127, 203 and 256 are scheduled to become part of "make
check-block", so we also do not have to test them seperately here anymore.
On the other side, new iotests have been added to the QEMU repository
in the past months, so we can now add some new test > 256 instead.

The qtests have recently been moved to a separate subdirectory, so
the paths that are mentioned in the documentation have to be adjusted
accordingly. And some of the iotests are now always run as part of
"make check", so this information has to be adjusted here, too.

vhost-user-bridge isn't actually a test, it's just a helper
(that should probably move somewhere else) - but the build was
broken in the qtest move.

Checking for uninitialized variables raises warning for file path
variables in test_logfile_write and test_logfile_lock functions.
To suppress this warning, initialize varibles to NULL. This is safe
change as result of g_build_filename is stored to them before any usage.

After 7dd547e5ab the env->llval value
is loaded as an unsigned value (instead of sign-extended as before).
Therefore, the CMPXCHG in gen_st_cond() in translate.c fails if the
sign bit is set in the loaded value.
Fix this by sign-extending the llval value for the 32-bit case.
I discovered this issue because FreeBSD MIPS64 was looping forever
in an atomic helper function when trying to start /sbin/init.
