If the kernel bug has been fixed, stat command fails to get i_size
and reports "Structure needs cleaning". So we use debugfs -R "stat"
instead of stat command to make sure debugfs sets negative i_size.
These cases have been broken by commit 0e13e40b24 ("shared/005,7:
make sure debugfs sets negative i_size").

shared/005 and shared/007 work abnornamlly on RHEL6.8GA and
RHEL6.9Beta because debugfs fails to set i_size to -1 or -512
and reports "exceeds field size maximum". When debugfs fails
to set a negative i_size, we can skip these cases which don't
trigger the kernel bug.

Craft a malicious filesystem image with a negative inode size,
then try to trigger a kernel DoS by appending data to the file.
Ideally this should trigger verifier errors instead of hanging.

There are couple of tests in shared directory which really should be
made generic, so move it. It is mostly collapse range tests, which
really can be generic to make super we test every file system which adds
collapse range support.
Here is what we're moving in this commit.
shared/001 -> generic/021
shared/002 -> generic/022
shared/003 -> generic/012
shared/004 -> generic/016
shared/005 -> generic/017
shared/218 -> generic/018
shared/305 -> generic/019

We execute collapse range multiple times on same file. Each
collapse range call collapses a single alternate block. After the
test execution, file will be left with 80 blocks and as much number
of extents. We also check for file system consistency after the
completion.
