Add the projects from the website (htdocs/contrib/projects.xml).

At this point, all this is is a "blind conversion" from the xml file to
individual mdwn files.  I did this by using a custom xslt file and some
manual cleanups on the files.

Most of these projects are still misclassified as they do not list the
correct difficulty or the category they list is not yet defined in the
wiki.  Some other projects need to be pruned out due to the lack of
details (or moved to the ideas page).  But this is a "good enough" start
that should allow me to nuke these same projects from htdocs.

title="Defragmentation for FFS"



Heavily used file systems tend to spread the blocks all over the disk,
especially if free space is scarce. Traditionally dump/restore have been used to
recreate the file system, but this is not acceptable for current disk
sizes. Since resize_ffs has to relocate blocks during shrinking anyway, it
should be possible to extend it to full reordering and defragmentation.
