[PATCH 3/3] *: use allowlist and denylist

["Derrick Stolee via GitGitGadget" <gitgitgadget@gmail.com>]

From: Derrick Stolee <derrickstolee@github.com>

Using "allowlist" and "denylist" is a more precise definition of the
functionality they provide. The previous color-based words assume
cultural interpretation to provide the meaning.

These changes to the Git codebase are mostly cosmetic. Several comments
are updated. The renamed protocol_allowlist() method is local to
transport.c so does not update any header file API definition. There are
some untranslated error messages that are reworded, so this _might_
affect error parsers. However, two of the three error messages are
around option parsing, so they are "fast failures". The one perhaps
meaningful change is the logerror() in daemon.c.

After this change, the only remaining uses of the previous words are
in release notes for older versions of Git.
