This is a developer-only feature, so it's gated via `HOMEBREW_DEVELOPER`.
This is intended to enable testing of macOS 10.15; users building software
manually to test compatibility of early betas need to be able to build
software from source instead of via pouring 10.14 bottles. This isn't
intended to be a general-purpose `HOMEBREW_BUILD_FROM_SOURCE` replacement,
and has no effect on released versions of macOS.
Adjust the rules based on the current codebase. Remove various enable,
disables and default values that are unnecessary. Add more comments
explaining why. Make minor changes needed to enable a few more rules.
Rather than relying on a `HOMEBREW_FORCE_BOTTLE` variable (which ends
up doing silly things like forcing bottle usage even when options are
provided) instead handle this at the `or_later` bottle detection
level so on prerelease versions of macOS any bottle looks like an
`or_later` bottle (unless various environment variables are set).

This does the equivalent of always passing `--force-bottle`. This will
be enabled by default on Mojave to allow people to avoid building
everything from source until our porting and bottling is a bit further
along.
Allow at `install` (or `install --only-dependencies`) time to specify
that test dependencies should be installed. This will allow simplifying
code in `brew test-bot`.
This could also be made an environment variable if desired by
maintainers.
If you specify a formula more than once or it exists in the Cellar with
an alias name and the main name (e.g. `qt` and `qt5`) you can see the
same formula showing up more than once. Instead, resolve these output
lists of formulae such that they are unique based on their `name`. This
doesn't use `full_name` as it's `name` that's use for the `Cellar`.
These were formerly supported but as it has been a very long time since
32-bit software was necessary on macOS these have been deprecated with
a `brew audit` warning and a future `odeprecated`.
This is a step closer to better argument handling but for now just
fixes the issue in #1217 where it starts complaining about options like
`--build-from-source` being used.
