Requirements:
Should be able to skip tests from run-tests.sh run.
Should be granular enough to disable on subset of OSes.

Solution:
Tests can have special comment lines with some comma separated values
within them.

Key names used to determine test status are
G_TESTDEF_TEST_STATUS_CENTOS6
G_TESTDEF_TEST_STATUS_NETBSD7
Some examples:
G_TESTDEF_TEST_STATUS_CENTOS6=BAD_TEST,BUG=123456
G_TESTDEF_TEST_STATUS_NETBSD7=KNOWN_ISSUE,BUG=4444444
G_TESTDEF_TEST_STATUS_CENTOS6=BAD_TEST,BUG=123456;555555
You can change status of test to enabled or delete the line only if all the
bugs are closed or modified or if the patch fixes it.

Problem:
Ec takes a ref of the request xdata and sets trusted.ec.version/algo etc xattrs
as part of it. But this request xdata could be using same dictionary to do the
operation on multiple subvolumes, due to which other subvolumes will have
internal xattrs of ec in it and will be created on subvols where they are not
supposed to appear.

Fix:
Take a copy of the request xdata/dict to prevent this from happening.

Most of the debugging work and test script is contributed by Nitya.
