Merge branch 'bw/grep-recurse-submodules' into bw/submodule-config-cleanup 

* bw/grep-recurse-submodules:
  grep: recurse in-process using 'struct repository'
  submodule: merge repo_read_gitmodules and gitmodules_config
  submodule: check for unmerged .gitmodules outside of config parsing
  submodule: check for unstaged .gitmodules outside of config parsing
  submodule: remove fetch.recursesubmodules from submodule-config parsing
  submodule: remove submodule.fetchjobs from submodule-config parsing
  config: add config_from_gitmodules
  cache.h: add GITMODULES_FILE macro
  repository: have the_repository use the_index
  repo_read_index: don't discard the index

<tree> option the prefix of all submodule output will be the name of
the parent project's <tree> object.
--parent-basename <basename>::
For internal use only. In order to produce uniform output with the
--recurse-submodules option, this option can be used to provide the
basename of a parent's <tree> object to a submodule so the submodule
can prefix its output with the parent's name rather than the SHA1 of
the submodule.
