[GSOC][RFC PATCH 0/2] add-patch: compare object id

[Ghanshyam Thakkar <shyamthakkar001@gmail.com>]

This patch series is RFC as this contains a partial behavior change.
The first patch introduces a new function to compare object id instead
of revision strings. The second patch removes the special case for HEAD
in builtin/checkout.c.

This patch series enables for HEAD to be specified in any form and
removes need to be kept a literal string 'HEAD'. Consequently, this
removes the need to keep a special case for HEAD in callers of
run_add_p() (as in builtin/checkout.c).
