enhancement proposal : customization of module files

- Gave setup_environment and setup_dependent_environment more similar
  signatures. They now allows editing the Spack env and the runtime
  env for *this* package and dependents, respectively.

- modify_module renamed to setup_dependent_python_module for symmetry
  with setup_dependent_environment and to avoid confusion with
  environment modules.

- removed need for patching Package objects at runtime.

- adjust packages to reflect these changes.

+ Installation of subversion may need to be modified to include python and perl
  bindings. I have provided comments to this end, but the code is not active.

fix petsc on osx

…up_dependent_package

- Fixed in package.py
- Fixed wrong prototypes in packages that use it.
- Fixed build_environment to set module variables properly
  - added hacky fix to ensure spec/package consistency in build processes.
  - Need to think about defensive spec copy done by `Repo.get`.  May be
    time to think about an immutable spec implementation.

+ Provide fpic variant for netlib-lapack.

+ libdrm depends_on libpciaccess.  Use spack provided libpciaccess.

Allow users to use spack to stage a, potentially complex, package into a
given path.  This is nice for packages with multiple resources that must
be placed, for example LLVM with all sub-projects.

This version actually pulls the path through the package to deliver it
to each stage on creation when passed through the command.  This is
necessary due to the new StageComposite class that makes setting the
path directly on the stage impractical, it also takes the logic out of
package for the most part, which seems like an improvement.

add a path argument to the stage command
