In many places in the code we do not have access to the individual fields
in the committer data. Instead we might only have access to prebaked data
such as what is returned by git_committer_info() containing a string
that consists of email, timestamp, zone etc.
This makes it inconvenient to use transaction_update_reflog since it means
you would have to first parse git_committer_info before you can call
update_reflog.
Add a new flag REFLOG_COMMITTER_INFO_IS_VALID to _update_reflog to tell it
that we pass in a fully prebaked committer info string that can be used as is.
At the same time, also go over and change all references from email
to id where the code actually refers to a committer id and not just an email
address. I.e. where the string is : NAME <EMAIL>
