Read cvsimport options from repo-config

Default values for command line options can be saved in .git/config (or the
global ~/.gitconfig). Config option names match the command line option names,
so cvsimport.d corresponds to git-cvsimport -d. One may also set
cvsimport.module to specify a default cvs module name.
