We were previously only looking at the `cellar` value when pouring
bottles and ignoring the `prefix` and (implicit) `repository`.
Actually look at these values and set the defaults for each platform.
Also, when we're relocating to create or pour bottles when `prefix`
and `repository` are equal then skip relocating the `repository` and
always use references to the `prefix` instead.
Fixes#9453
We can pass Integers here too, for e.g. make flags

TypeError: Parameter 'args': Expected type T.any(Pathname, String), got type Integer with value 4

- set `Formula#force_bottle` from `FormulaInstaller`
- refuse to install non-bottled formulae with `--force-bottle`
- raise exceptions on fetch/pour failures if `--force-bottle is passed.
While we're here:
- use `CannotInstallFormulaError` for some `RuntimeError`/`odie`
Fixes https://github.com/Homebrew/brew/issues/8866.
The way we currently handle @-versioned formulae linking is pretty
labourius:
- it requires extensive use of `link_overwrite` to avoid the `link`
stage failing on certain install/upgrade scenarios
- we teach people to use `brew link --force` whenever they wish to
link a versioned formulae when it's pretty obvious what's expected
in that situation
Instead, let's:
- automatically unlink other versioned formulae when linking a
versioned formula (either through `brew link` or `install`/`upgrade`
/`reinstall`)
- notify the user what we've done (with the same messaging as if
they had run `brew link` manually)
Ensure that we don't try to check for broken linkage in a keg that
doesn't exist. Furthermore, fix the reason we checked for the keg that
doesn't exist by `Formula.clear_cache`.
While here, I noticed that there was other methods of caching at use in
`Formula` so consolidate them to be consistent.
Fixes#8997
