Review request for mesos, Vinod Kone, Jie Yu, and Ben Mahler.
Description
-------
* Added new test fixtures:
(1) CgroupsNoHierarchyTest for running tests where we need to create
a hierarchy (and thus, most likely, no existing hierarchy can
exist because it will already have the cpu and or memory
subsystem attached).
(2) CgroupsAnyHierarchyTest and subclasses
CgroupsAnyHierarchyWithCpuMemoryTest and
CgroupsAnyHierarchyWithCpuMemoryFreezerTest for running tests
with any hierarchy provided it has necessary subsystems
attached.
* Renamed cgroups (from "prof", "stu", etc. to "mesos_test") and
removed nested cgroups by default. The rename was done because we
might run tests inside of an existing hierarchy and we want to avoid
name clashes. The nested cgroups were removed in favor of a test
that explicitly tries to create nested cgroups (since some older
kernels with particular subsystems attached have a hard time with
this, and we'd like to detect that case explicitly).
* Created an explicit test for nested cgroups (see above).
* Updated the "write control" test to use a forked process rather than
the test process (to be more conservative in the presence of errors)
* Updated the "listen event" (i.e., "oom") test to check for the
proper control first (memory.oom_control).
* Updated the failure mechanism of forked (children) processes to use
'abort' rather than 'ASSERT_*' and 'FAIL' in order to make test
output more readable upon failures.
* Updated the notify mechanism from forked (children) processes to
parent processes to correctly distinguish a closed pipe from a value
written (to catch more instances of when the test is actually
failing).
