tests on MIPS64EB in QEMU.

r327346:
Fix potential TOCTTOU bug in the geli tests

This change mostly reverts r293436, which introduced the bug due to a belief
that geli(8) would allocate md(4) devices by itself. However, that belief is
incorrect. Instead of using linear probing to find available md(4) numbers,
it's best to use the existing attach_md function.

r327347:

No functional change.

r327352:
Fix a harmless typo from r310786

I copy/pasted a reference to an undefined shell variable.

r327353:
geli: fix the resize test on arm64

The resize test used bsdlabel(8), which is not available on all
architectures.  Change it to use gpart(8) instead, which should be available
everywhere.

r327662:
geli: convert most tests from TAP to ATF

I'm leaving readonly_test and nokey_test alone for now. In a future commit
they should be broken up into several smaller test cases and distributed
between multiple files.

r327666:
geli: fix parallel execution of tests

The trick is not to destroy an md(4) device during a test.  That can create
a "double-free" situation, because we also destroy md devices during test
cleanup.

r327682:
Fix typo from r327666

r327683:
geli: convert remaining TAP tests to ATF

r327685:
geli: optimize tests

Reduce the geli tests' runtime by about a third:

* In integrity_test:copy, use a file-backed md(4) device instead of a
  malloc'd one.  That way we can corrupt the underlying storage without
  needing to detach and reattach the geli device.

* In integrity_test:{copy, hmac, data} and onetime_test:{onetime,
  onetime_a}, move reads of /dev/random out of the loop.
