If folks have set `HOMEBREW_DEVELOPER` or run a `dev-cmd` then enable
environment filtering by default for them.
 | 
 | 
Use HOMEBREW_AUTO_UPDATE_CHECKED variable.
 | 
 | 
Rather than reusing `HOMEBREW_NO_AUTO_UPDATE` to indicate that we've
already made a check. This allows `HOMEBREW_NO_AUTO_UPDATE` to be
displayed properly by `brew config`.
 | 
 | 
 | 
 | 
Exclude the boring ones and exclude some that are already printed that
are just using their default values. HOMEBREW_PREFIX is the only one
where we’re always interested in the output to quickly communicate it.
 | 
 | 
 | 
 | 
This is the actual user path when env filtering is enabled.
 | 
 | 
Suppress the error message:
Unable to find any JVMs matching version "(null)".

Now that Python has been renamed it's important that we still output
which Python they are using for debugging purposes e.g.
```
Python: /usr/local/opt/python/libexec/bin/python => /usr/local/Cellar/python/2.7.13_1/Frameworks/Python.framework/Versions/2.7/bin/python2.7
```

Fixes #2192
 | 
 | 
These should have been deprecated long ago but we didn’t really have
the necessary framework to do so.
 |

Not quite a mass replacement as I've used OS X and Mac OS X where
describing specific older versions and added compatibility methods
for things in the DSL.
 | 
 | 
But remove some manual `.freeze`s on constants that shouldn't be
constants.
 | 
 | 
 | 
 | 
 | 
 | 
Due to our SCM wrapper in `Library/ENV/scm/git`, lookup is a bit more
complicated than just picking the first match in `PATH`. Make debugging
easier by printing the version and path of the Git actually used by us.
 | 
 | 
At this point it's never a good compiler to use so let's just remove it.
 | 
 | 
Closes #168.
