Correct the link to Homebrew on Linux GitHub issues

Resource#fetch: verify downloads by default.

This API is used internally correctly and externally mostly correctly
but #6230 reveals the external usage is fairly confusing and a bit
unsafe by default. Preserve the existing API while verifying the
checksum by default and providing an opt-out. Using the existing, safe
method will result in a double verification of the checksum which is
harmless. A Homebrew/homebrew-core PR will follow shortly to address
those cases.

Fixes #6230

These are being introduced in e.g.
https://github.com/Homebrew/homebrew-bundle/pull/486 and we don't care
about them in Homebrew bug reports.

audit: check bind for development versions

java_requirement: set cask attribute

Set `@cask` attribute for JavaRequirement, which is used by
`brew info` to track cask requirement for formulae and
`brew bundle dump` to sort the formulae and casks.

Before:
```
$ brew info --json languagetool | jq '.[0].requirements'
[
  {
    "name": "java",
    "cask": null,
    "download": null
  }
]
$ brew cask install adoptopenjdk; brew install languagetool
$ brew bundle dump
brew "languagetool"
cask "adoptopenjdk"
```

After:
```
$ brew info --json languagetool | jq '.[0].requirements'
[
  {
    "name": "java",
    "cask": "adoptopenjdk",
    "download": null
  }
]
$ brew cask install adoptopenjdk; brew install languagetool
$ brew bundle dump
cask "adoptopenjdk"
brew "languagetool"
```

Also added relevant test cases.

Bottles: allow skipping or_later tags

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.
