Add short options for most long options. Rename the -i option to -H, but
support -i for compatibility until the next release cycle, where -i will
become the short option of --identifier. Rename --include to --headers
and support --include until the next release cycle.
Add carray(1) manual page which makes --help unnecessary, and remove
--version as it surely matches your local Sortix version.
