The package index considers may yield develop dists found on its local search_path - sys.path by default - in addition to its index_url. This commit discards such dists when they do not contain a setup.py nor a pyproject.toml, as a good heuristic of whether they will be installable or not.

This option determines what paths zc.buildout will scan for already installed distributions. It can be set to an empty value to enable isolation. The special values 'sys.path', 'legacy' and 'zc.buildout' expand to particular paths. The default is 'zc.buildout'. The 'sys.path' mode simply expands to the currrent sys.path. The 'legacy' mode reproduces the previous behavior of specifically scanning the paths of the current zc.buildout distribution and its dependencies using a weird ordering logic that bears no relation to the order they appear in sys.path - which can produce unexpected results as other distributions for zc.buildout, pip, wheel and setuptools may take precedence over the ones currently running. The 'zc.buildout' mode is similar to 'legacy' as it uses only the paths of the currently running zc.buildout and dependencies, but unlike 'legacy' mode it respects the order in which these appear in sys.path, avoiding unexpected results. This mode is set to the default because it is closest to 'legacy' mode and because it has a nice property: running in succession `buildout buildout:extra-paths= bootstrap` (1) `bin/buildout` (2) will result in (1) installing zc.buildout and its dependencies in ./eggs in isolation from the environment, and (2) using only the paths of these in ./eggs, i.e. continuing to operate in isolation, even without setting extra-paths explictly.

In bootstrap we potentially copy eggs from the working set to ./eggs. We then reconstruct the same working set using the moved locations. This commits ensures we keep a correct working set order throughout and that we avoid activating unintended dists.

If a dist in the computed working set is at a location shared with other dists - such as site-packages - then when generating scripts these other packages may overshadow the next items on the sys.path and result in importing a different version than the one installed and intended by buildout. To avert this, a sort of the working set was introduced at various points just before generating a script. However, that sort put the paths referenced from an `.egg-link` in ./develop-eggs first. This is truly problematic because dists from site-packages which are not eggs - e.g. dists installed with pip - can become referenced as `.egg-link` during buildout bootstrap and the sort then causes site-packages to be one of the first items in sys.path. In particular when running buildout bootstrap from a venv in which zc.buildout was installed by pip, if any one of zc.buildout or its dependencies from the venv meets the version requirements, then it can cause the generated bin/buildout to import the dists only from the venv's site-packages, even when some do not meet requirements. To fix this, the sort now puts the dists from `./eggs` first as we know their locations contain only a single dist, and then puts the dists from ./develop-eggs which have locations inside the buildout directory before the others. The previous sort was also activating all the dists from the paths of the already activated dists. Note that this also means that any working set must be manipulated with care in general to avoid activating unintended dists from the locations of the already activated dists.

Replace `pkg_resources.Environment(ws.entries).best_match(req, ws)` with `ws.find(req)`. The first already starts by calling `ws.find(req)` to attempt to find an already activated dist in the working set, but if none is found it then proceeds to scan through the entries of the environment - i.e. the locations of the directly-requested distributions, `ws.entries` - to activate a dist at these locations if one matches. This is problematic when directly-requested distributions are found in a location shared by multiple dists, such as site-packages: this gives that location precedence over the normal order of locations scanned by easy_install, and can result in undesired versions being chosen over versions available in ./eggs or in ./develop-eggs. The random aspect of this is also problematic, as the order of paths considered will depend on the order of the directly-requested distributions and where they are found.

If zc.buildout or its dependencies have pinned versions that do not match the currently running versions, they are now installed in the local eggs directory from scratch according to the pinned versions. In offline mode this merely ensures that versions that satisfy the requirements are already available. This is the case when the eggs are already installed, or when the running versions are a match to the pinned versions or the absence of a pinned version. If after this matching versions of zc.buildout and its dependencies are not located in the local eggs or develop-eggs directories, they are copied there as was already the case before.

When generating an environment dict for subprocess calls to pip, os.environ was accidentally modified despite efforts to copy it and modify only the copy, as copy.copy(os.environ) is not enough.
