Skews a totl twice, restore it, and intersperse setfattr/unlink to
exercise both injected and naturally-produced deltas.

Two test programs are added. The run time is about 1min on my el7
instance.
The test script finishes up with a read/write mmap test on offline
extents to verify the data wait paths in those functions.
One program will perform vfs read/write and mmap read/write calls on
the same file from across 5 threads (mounts) repeatedly. The goal
is to assure there are no locking issues between read/write paths.
The second test program performs consistency checking on a file that is
repeatedly written/read using memory maps and normal reads and writes,
and the content is verified after every operation.

Add a test binary that uses o_tmpfile and linkat to create a file in a
given dir. We have something similar, but it's weirdly specific to a
given test. This is a simpler building block that could be used by more
tests.

There were kernels that didn't apply the current umask to inode modes
created with O_TMPFILE without acls. Let's have a test running to make
sure that we're not surprised if we come across one.

Add a utility that mimics our search_xattrs ioctl with directory entry
walking and fgetxattr as efficiently as it can so we can use it to test
large file populations.
