[RFC/PATCHv0 4/4] fast-import.c:note_change_n(): Rename commit_* to target_*

[Johan Herland <johan@herland.net>]

Since we now allow adding notes to any kind of object (not just commits),
rename the related variables from "commit_*" to "target_*".

TODO: Also replace "commit-ish" with something more suitable in the
documentation. However, the same needs to be done for the 'tag' command,
and we also the BNF at the top of fast-import.c needs corresponding updates.
