check-mailmap: add options for additional mailmap sources

The git check-mailmap command reads the mailmap from either the default
.mailmap location and then from the mailmap.blob and mailmap.file
configurations.

A following change to git send-email will want to support new
configuration options based on the configured identity. The
identity-based configuration and options only make sense in the context
of git send-email.

Expose the read_mailmap_file and read_mailmap_blob functions from
mailmap.c.  Teach git check-mailmap the --mailmap-file and
--mailmap-blob options which load the additional mailmap sources.

Read contacts, one per line, from the standard input after exhausting
contacts provided on the command-line.
--mailmap-file=<file>::
In addition to any configured mailmap files, read the specified
mailmap file. Entries in this file take precedence over entries in
either the default mailmap file or any configured mailmap file.
--mailmap-blob=<blob>::
Like `--mailmap-file`, but consider the value as a reference to a
blob in the repository. If both `--mailmap-file` and
`--mailmap-blob` are specified, entries in `--mailmap-file` will
take precedence.
