Changes from 1.12.99.0 to 1.12.99.1

- When installing a file over a file that is not tracked by any

  package, save the previous one as .pkgsave

- Fix a chicken/egg problem with the meta being compressed and defining

  the compression format. Now pkg repo will create a meta.conf file

  uncompressed (it is small enough) and fallback on the old meta.txz.

  Note that meta.txz is still created for backward compatibility

- pkg repo now creates meta files in version 2 by default meaning the digests.txz

  is not created anymore, it was only used up to pkg 1.2. anyone upgrading

  from pkg 1.2 should first run pkg bootstrap -f to be on a recent version.

- pkg -r now first lookup under the rootdir for its ABI_FILE.

- suppress version checking when -j is specified

- Alphabetically sort packages printed in the output of pkg commands to ease readability

- pkg lock/unlock now allows multiple packages in arguments
