We don't have perfect control of file allocation for these tests;
in some cases we may fail to adequately fragment a file prior to
defragmentation testing, and today that will fail the test.
Attack this on 2 fronts:
1) Explicitly allow fewer extents on one of the input files in
generic/018 where the allocator has discretion.
2) _notrun rather than _fail if we don't create enough extents;
this is a defrag test, not an allocator/fragmentation test,
so just skip the test if we can't create an acceptable file
for defrag testing.

Currently _link_output_file() selects output file suffix based on the
current operating system. Make it more versatile by allowing selection
of output file suffix based on any feature string. The idea is that
in config file ($seq.cfg) there are several lines like:
feat1,feat2: suffix
The function is passed a feature string (or uses os_name,MOUNT_OPTIONS
if no argument is passed) and selects output file with a suffix for
which all features are present in the feature string. If there is no
matching line, output with 'default' suffix is selected.
Update all tests using _link_out_file to the new calling convention.

The runas helper runs a command as another user and/or with different group
memberships. Fix the following problems:
* Use setgid instead of setegid and setuid instead of seteuid.
Otherwise, the command will run with the original real UID
and/or GID; those could be made the effective IDs again.
* When only a GID is specified, remove all supplementary
GIDs. Otherwise, the command would remain in the same
supplementary groups as runas -- which often is the root
group.
* Use execvp instead of execv which searches the PATH when
necessary. The runas helper is always called either with a
'/' in the pathname or as "runas ... `which program`", so
we obviously want PATH lookup, anyway.
* There is no advantage in fork'ing and waiting for the child
over directly exec'ing the command; the test cases already
have to deal with commands which can be killed by signals.

generic/085 was failing on a machine w/o devicemapper kernel
support because it requires the linear target, but didn't
explicitly test for it.
I could have cut & pasted _require_dm_linear(), but chose
to go the route of a generic helper, _require_dm_target $FOO,
because some day someone will need the zero target, the error
target, or who knows.
Add the helper, use it in test generic/085, and convert
_require_dm_flakey, _require_dm_snapshot, and
_dmerror_required with this new helper.
