RFC: Pass TRIM through GELI

[Matthew D. Fuller]

> I've done a quick implementation of TRIM passthru support for GELI.

Here's a slightly updated version.  Some adjustments to the manpage
suggested by jmg@, and I've stripped out the new version and checks
for it.

<http://www.over-yonder.net/~fullermd/dl/geli-delete.2.patch>

Should be functionally the same as the prior, with the exception of
the version checks.
