git-svn: remove the 'rebuild' command and make the functionality automatic

Since refs/remotes/* are not automatically cloned, we expect the
user to be capable of copying those references themselves
anyways.

Also removed the documentation for --ignore-nodate while we're
at it; it has also been made automatic.

-COMPATIBILITY OPTIONS
----------------------
---
-
---upgrade::
-Only used with the 'rebuild' command.
-
-Run this if you used an old version of git-svn that used
-"git-svn-HEAD" instead of "remotes/git-svn" as the branch
-for tracking the remote.
-
---ignore-nodate::
-Only used with the 'fetch' command.
-
-By default git-svn will crash if it tries to import a revision
-from SVN which has '(no date)' listed as the date of the revision.
-This is repository corruption on SVN's part, plain and simple.
-But sometimes you really need those revisions anyway.
-
-If supplied git-svn will convert '(no date)' entries to the UNIX
-epoch (midnight on Jan. 1, 1970).  Yes, that's probably very wrong.
-SVN was very wrong.
