History
Adam Simpkins 37fd4f5cfb add a fault injection framework 
Summary:
Add a new class for injecting faults into Eden.  This will make it easier to
build tests that exercise specific error conditions or specifically control
the ordering of operations that might otherwise race.

To minimize the performance impact, the fault injection framework is disabled
by default and must be explicitly enabled at process startup using a command
line flag.  If this command line flag was not specified all fault injection
checks short-circuit into a no-op.  The `checkAsync()` version does still add
some extra overhead due to the addition of a new `folly::SemiFuture` into the
code path.
