[PATCH v2 0/3] Test oidmap

Unlike hashmap that has t/helper/test-hashmap.c and t/t0011-hashmap.sh oidmap has no specific test. The goal of this small patch series is to change that and also improve oidmap a bit while at it.

Changes compared to V1 are the following:

  - use printf("%x\n", ntohl(sha1hash(oid.hash))) to print hashes as
    suggested by Gábor and approved by Junio,

  - use `git rev-parse "$1" | cut -c1-8` to check hashes in t0016 as
    suggested by Gábor,

  - removed PERL prereq on "hash" test in t0016 as allowed by the
    above change and suggested by Gábor,

  - removed suprious space between ">" and "expect" in t0016 as
    suggested by Gábor.

I decided against hardcoding values as I think it might help transitionning from SHA1 to SHA256.

Christian Couder (3):
  t/helper: add test-oidmap.c
  t: add t0016-oidmap.sh
  oidmap: use sha1hash() instead of static hash() function
