[Toybox] [PATCH v2 0/2] Teach file about archive formats, tidy up

[Isaac Dunham]

Hello,
Here are a couple patches for file.
 [PATCH 1/2] pending/file: add cpio, tar, zip formats.
 [PATCH 2/2] pending/file: reuse int
Patch 1 is a rebased version of my previously sent patch to teach
file about cpio/tar/zip.
Patch 2 is 'cleanup' from that, because there are a few cases where an
int is used to store the results of a peek.
(I separated it out, because I'm not as sure about that part.)

Thanks,
Isaac Dunham
