git-svn, perl/Git.pm: extend and use Git->prompt method for querying users 

git-svn reads usernames and other user queries from an interactive
terminal. This cause GUIs (w/o STDIN connected) to hang waiting forever
for git-svn to complete (http://code.google.com/p/tortoisegit/issues/detail?id=967).

This change extends the Git::prompt helper, so that it can also be used
for non password queries, and makes use of it instead of using
hand-rolled prompt-response code that only works with the interactive
terminal.

Query user C<PROMPT> and return answer from user.

Honours GIT_ASKPASS and SSH_ASKPASS environment variables for querying
the user. If no *_ASKPASS variable is set or an error occoured,
the terminal is tried as a fallback.
If C<ISPASSWORD> is set and true, the terminal disables echo.
