cmdutil: enhance "getcommiteditor()" for specific usages in MQ

This patch introduces "finishdesc" and "extramsg" arguments into
"getcommiteditor()" for specific usages in MQ.

"finishdesc" will be used to treat the commit message as "[mq];
patch-file-name" (default MQ commit message), if it is left as empty,
instead of aborting commit process.

"extramsg" will be used to show the line below:

    HG: Leave message empty to use default message

instead of:

    HG: Leave message empty to abort commit

    'finishdesc' is a function to be called with edited commit message
    (= 'description' of the new changeset) just after editing, but
    before checking empty-ness. It should return actual text to be
    stored into history. This allows to change description before
    storing.

    'extramsg' is a extra message to be shown in the editor instead of
    'Leave message empty to abort commit' line. 'HG: ' prefix and EOL
    is automatically added.

    'getcommiteditor' returns 'commitforceeditor' regardless of
    'edit', if one of 'finishdesc' or 'extramsg' is specified, because
    they are specific for usage in MQ.
