SCons renaming updates for base, net and googleurl:

* Rename SConscript files to {module}.scons or {moduel}_lib.scons,
  depending on the primary target involved.
* Separate targets into individual *.scons files, with one
  construction environment (named "env") per *.scons file.
* Add using_{module}.scons files (like .vsprops) that will be used
  by other modules to add CPPDEFINES, CPPPATH, LIBS and LIBPATH values.
* Update other modules' *.scons files to use the new using_{module}.scons
  files (using a temporary one-liner idiom until we have the
  ApplySConscript() method from the Hammer modules).
* Use the idiom of removing to-be-ported files from the master list,
  so they can be simply deleted from the to-be-ported list as they
  get ported in the future, instead of having to shuffle entries
  between lists.
* Use $OBJ_ROOT instead of hard-coded '#/$BUILD_TYPE/' for the $*_DIR
  variables.
* Add a addRepository() call mapping build/ to $TARGET_ROOT/googleurl,
  so its $OBJ_ROOT value can look like the others'.
* Formatting changes, primarily modifying indentation to conform to
  style guidelines.
* Fix copyright headers in some third_party/* modules
  previously overlooked.
* Add rudimentary __doc__ strings, setting up for a future
  ability to generate meaningful documentation.
