Unfortunately, FreeBSD doesn't support sparse files in their tmpfs,
and they generlaly don't mount a tmpfs on /tmp anyway. As a result
certain tests will either OOM kill a FreeBSD (if tmpfs is in use) or
will take forever (if it is not in use).
So let's turn off some tests for FreeBSD (m_hugefile is disabled on
MacOS already, for similar reasons). We need to find a better
solution in the long term, but for now, these tests are guaranteed to
be a disaster on FreeBSD, so suppress them for now.

Old distros may not have the "truncate" tool, so use "dd" instead.
If tmpfs cannot handle a 2GB temp file (e.g. old RHEL5 and SLES 11
kernels) then skip the test instead of failing it. If this fails,
try to report better error messages instead of failing silently.

The new resize tests create 2TB test files, but tmpfs in kernels
before 3.1 have a max file size of 256GB. Ext3 may also have
a size limit for smaller blocksize filesystems.
Fix the resize_test script to verify that $TMPFILE can be resized
to the final test size, and if that fails try creating the file on
the local filesystem instead of in $TMPDIR. If that cannot hold
the large filesystem, skip the test.
