Upstream have dropped support for OS X in the latest release.

Closes Homebrew/homebrew#49442.

Upstream is completely dead, formula hasn't been updated to the most recent
release which was available years ago, tried to update and resulting install
doesn't seem to function as expected.

Closes Homebrew/homebrew#49635.

Looks like the bintray publish_wait_for_secs was being ignored because the
content type wasn't being set, so it defaulted to x-www-form-urlencoded
instead of application/json.

Changes the  timeout to 0 to preserve current non-blocking behavior, which
we want in case multiple formulae are being updated.

- Use empty array when `git credential-osxkeychain` lookup fails to
  cache and avoid rerunning it when there's no valid results.
- Redirect `stderr` to avoid printing errors when there's a failure
  or no `git credential-osxkeychain` installed.

If it's not a tap, we test formula on CoreTap. This can happen
if we run test on a fork, e.g. Linuxbrew or future Homebrew/brew.

Instead of hard coded `Homebrew/homebrew`

To keep backward compatibility for API name changing.

Core tap will be separated from core code in the near future.
It makes sense to rename it to CoreTap.

MLton is whole-program, optimizing compiler for Standard ML.

A previous mlton formula simply installed the upstream binary release
and was moved to the boneyard as a binary-only formula (see
Homebrew/homebrew#21780).

This new mlton formula builds from source, using the upstream binary
release to bootstrap.

These methods will be used in `brew --version`, `brew config`

This commit will help to mitigate bug Homebrew/homebrew#42553 on certain old Homebrew installations
(e.g. `osx_image: xcode6.4` on Travis CI) for future core/formula
separation.

On that particular Homebrew installations, `formulary.rb` will be loaded after
`git pull` is finished during `brew update`, which will then load `core_formular_repository.rb`.

By introducing `require "tap_migrations"` and `require "formula_renames"` at the top of
`core_formular_repository.rb`, we could use `tap_migrations.rb` as a
vector to preform certain hack for future core/formula separation.

If a formula's class name contains an uppercase-spelled acronym, the
messages given by `brew install` can be pretty confusing (it recommends
a formula named exactly the same…)

Based on recent feedback on some pull requests, I touched up the section about adding tests to formula.
I wanted to make it clearer that the examples demonstrate how to create files on the fly and add a pointer to the tinyxml2 formula (DomT4 pointed it out to me as a good example).

Follow-up to Homebrew/homebrew#49327 that leaves empty argument handling to the Ruby code
(it is a bit more sophisticated and distinguished between `help` and an
empty argument list and treats them differently) instead of hard-wiring
the former to the `help` command.

Because the versions are read from directory listings, we get
alphabetical sorts of version numbers in `brew outdated` output:

   some-keg (10.1.10, 10.1.11, 10.1.9 < 10.1.12)

This is nicer:

The current approach of suppressing all output regardless of what the
error is makes it very hard to debug any issues and misread but valid
Mach-O files will be silently interpreted as non-Mach-O files instead.

Prefer to fail if we are a Homebrew developer or running on the bot
(`HOMEBREW_DEVELOPER=1`), so that problems will be noticed and fixed
before the silent failure leads to hard-to-diagnose user problems.
