git-svn: lazy load some modules
We can delay loading some modules until we need them for uncommon
code paths. For example, persistent memoization is not often
needed, so we can avoid loading the modules for it until we
encounter svn::mergeinfo during fetch.
This gives a tiny reduction in syscalls (from 15641 to 15305) when
running "git svn info" and counting via "strace -fc". Further,
more invasive work will be needed to noticeably improve performance.
