This improves the load time of most brew commands. For an example of
one of the simplest commands this speeds up:
Without Bootsnap:
```
$ hyperfine 'git checkout master; brew help' 'git checkout optimise_requires; brew help'
Benchmark 1: git checkout master; brew help
Time (mean ± σ): 525.0 ms ± 35.8 ms [User: 229.9 ms, System: 113.1 ms]
Range (min … max): 465.3 ms … 576.6 ms 10 runs
Benchmark 2: git checkout optimise_requires; brew help
Time (mean ± σ): 383.3 ms ± 25.1 ms [User: 133.0 ms, System: 72.1 ms]
Range (min … max): 353.0 ms … 443.6 ms 10 runs
Summary
git checkout optimise_requires; brew help ran
1.37 ± 0.13 times faster than git checkout master; brew help
```
With Bootsnap:
```
$ hyperfine 'git checkout master; brew help' 'git checkout optimise_requires; brew help'
Benchmark 1: git checkout master; brew help
Time (mean ± σ): 386.0 ms ± 30.9 ms [User: 130.2 ms, System: 93.8 ms]
Range (min … max): 359.5 ms … 469.3 ms 10 runs
Benchmark 2: git checkout optimise_requires; brew help
Time (mean ± σ): 330.2 ms ± 32.4 ms [User: 93.4 ms, System: 73.0 ms]
Range (min … max): 302.9 ms … 413.9 ms 10 runs
Summary
git checkout optimise_requires; brew help ran
1.17 ± 0.15 times faster than git checkout master; brew help
```
This caused some JSON output to break recently which is not ideal.
The change here is to check if the output should be diverted to
stderr based on the options passed to system. If `:out => :err`
is passed, then we should send any verbose output to stderr
as well.
```console
$ brew ruby -e 'Homebrew.system("ls", :out => :err)' 2>| wc -c
105
$ brew ruby -e 'Homebrew.system("ls")' | wc -c
105
```
Ever since we started using this at runtime it's been polluting
the backtrace output. This makes it harder to debug errors and
increases the amount of info users have to paste into the box
when filing an issue.
This is a very direct approach. Essentially, we strip out
everything related to the `sorbet-runtime` gem whenever the top
line in the backtrace is unrelated to sorbet-runtime.
The hope is that this will allow errors related to sorbet to
be diagnosed easily while also reducing the backtrace size
for all other types of errors.
Sometimes it is useful to see the full backtrace though.
For those cases, we include the full backtrace when
`--verbose` is passed in and print a warning that the
Sorbet lines have been removed from the backtrace the
first time they are removed.
Note: This requires gems to be set up so that the call to
`Gem.paths.home` works correctly. For that reason, it must
be included after `utils/gems` which is included in
`standalone/load_path` already.
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.
