[PATCH v5 0/4] submodule config lookup API

There have been no code changes in since the last iteration. I changed
the title for the first patch since I realized that the cache is just an
implementation detail and what we are really doing is to provide a new
API for reading values from .gitmodules. I also added an extra paragraph
in the commit message explaining that fact.

The last iteration can be found here:

http://article.gmane.org/gmane.comp.version-control.git/270545

There is no interdiff since no code changed.

Heiko Voigt (4):
  implement submodule config API for lookup of .gitmodules values
  extract functions for submodule config set and lookup
  use new config API for worktree configurations of submodules
  do not die on error of parsing fetchrecursesubmodules option
