Update inflate code: fixed tables, bugfixes, zcat alias.
Update status page.
Add crc code: zcat now works.
Add -H option to cksum (hex output), fix to use FLAG macros.
CLEANUP transitions require all the generated/flags.h stanzas always be present (even for commands disabled in the config) to avoid undefined symbol errors referencing FLAG_ macros.
Put all FOR_xxx blocks after all CLEANUP_xxx in generated/flags.h so the usages don't have to be in alphabetical order.
