Greg Becker 7a6268593c Environments: specify packages for developer builds (#15256) ... * allow environments to specify dev-build packages * spack develop and spack undevelop commands * never pull dev-build packges from bincache * reinstall dev_specs when code has changed; reinstall dependents too * preserve dev info paths and versions in concretization as special variant * move install overwrite transaction into installer * move dev-build argument handling to package.do_install now that specs are dev-aware, package.do_install can add necessary args (keep_stage=True, use_cache=False) to dev builds. This simplifies driving logic in cmd and env._install * allow 'any' as wildcard for variants * spec: allow anonymous dependencies raise an error when constraining by or normalizing an anonymous dep refactor concretize_develop to remove dev_build variant refactor tests to check for ^dev_path=any instead of +dev_build * fix variant class hierarchy		2020-10-15 17:23:16 -07:00
