From: Jacob Keller <jacob.keller@xxxxxxxxx>
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.
