This sets the default and allows customising how often we try to
download files from the API.
This does not affect `brew update` as we want to always check every time
on an explicit call.
- remove all places we check the flag so it's a no-op now
- flip the messaging to refer to `HOMEBREW_NO_INSTALL_FROM_API` where
relevant
- adjust the documentation
When either being in a non-default prefix or being on an unsupported
macOS version we expect most things to be built from source. In that
environment, do not allow HOMEBREW_INSTALL_FROM_API to be set.
Fixes#14475
This allows HOMEBREW_INSTALL_FROM_API functionality to be disabled and will stick around once
HOMEBREW_INSTALL_FROM_API is made the default behaviour.

This doesn't need to be nearly as often for HOMEBREW_INSTALL_FROM_API users because we're getting the latest information from the API when needed rather than just at `brew update` time.
We added the `--all` flag (now renamed to `--eval-all`) for various
commands for this behaviour so let's start deprecating this.
Also, introduce a `HOMEBREW_EVAL_ALL` environment variable to use the
existing, less secure, behaviour by default and avoid passing
`--eval-all` everywhere.
Follow up to #13453. The default values for our other environment
variables are typically wrapped in backticks, so let's do the same here
for consistency.
Closes#13455.
From reading https://github.com/orgs/Homebrew/discussions/3328: I
initially thought we should just change "Updated" to "Modified" when
appropriate. After conversation with Bo98, though, I thought more and
saw that we're already checking for outdated formulae here so, rather
than ever traverse through the formula history, look at the outdated
formula and list them unless we've set
`HOMEBREW_UPDATE_REPORT_ALL_FORMULAE` in which case we show the
modifications.
While we're here, also do a bit of reformatting and renaming to better
clarify intent.
- Rename use of "preinstall" to "auto update". The original "preinstall"
naming came from the fact that we used to only auto-update before
`brew install` but now that it's many commands: this is more confusing
than useful.
- Add `HOMEBREW_NO_UPDATE_REPORT_ONLY_INSTALLED` and remove
`HOMEBREW_UPDATE_REPORT_ONLY_INSTALLED`; the latter is now the default
and the prior provides an opt-out for better output, performance and
avoiding reading potentially untrusted formulae.
- Add `HOMEBREW_UPDATE_FORMULA_VERSION_CHECKS` and don't check formula
versions by default for better performance by default.

Output hints for disabling automatic `brew update`, `brew cleanup` and
`brew upgrade`/`brew reinstall` of dependents. Also provide a
`HOMEBREW_NO_ENV_HINTS` to disable this messaging.
There's a few bits of functionality that Homebrew has changed over the
years, makes sense as a sensible default but some people find really
annoying:
- automatically running `brew update`
- automatically running `brew cleanup`
- automatically upgrading outdated dependents
- automatically reinstalling broken dependents
For each of these: let's improve the documentation of the commands
whose behaviour is changed and the environment variables themselves.
