Stephen Boyd 5a56da5806 read-tree: migrate to parse-options
Cleanup the documentation to explicitly state that --exclude-directory
is only meaningful when used with -u. Also make the documentation more
consistent with the usage message printed with read-tree --help-all.

The -m, --prefix, --reset options are performing similar actions
(setting some flags, read_cache_unmerged(), checking for illegal option
combinations). Instead of performing these actions when the options are
parsed, we delay performing them until after parse-opts has finished.

The bit fields in struct unpack_trees_options have been promoted to full
unsigned ints. This is necessary to avoid "foo ? 1 : 0" constructs to
set these fields.
