Per @UniqMartin's advice, avoid disabling shellcheck rules.

Per @UniqMartin's advice, the original code will fail to handle flags
like `-vd`, because once a case is handled, no other cases are evaluate.

When invoking --simulate-from-current-branch, we shouldn't do any file
manipulation.

* only set HOMEBREW_UPDATE_BEFORE inside pull instead of fetch.
* fix HOMEBREW_UPDATE_BEFORE/AFTER variable settings. They should be set
  to INITIAL_REVISION and CURRENT_REVISION correspondingly.
* avoid unnecessary duplicated shellout.
* remove unused variable.

* make sure exit after reset.
* more wide guardian range. We should trap reset_on_interrupt as soon as
  we are about to change any files.
* check INITIAL_BRANCH against UPSTREAM_BRANCH

rename_taps_dir_if_necessary must be performed before actual update.
Otherwise, it will report that `HOMEBREW_UPDAET_BEFORE<REPO_VAR>` is
unset.

* use HOMEBREW_REPOSITORY instead of HOMEBREW_PREFIX
* better performance:
  * update-bash: avoid shellout
  * update-report: use strip_prefix and tr
* more robust:
  * explicitly handle the case when repo is HOMEBREW_REPOSITORY to avoid
    to handle the trailing backslash.
  * handle both lower case and upper case when stripping non alpha and
    digital characters.

While running a command from the integration tests, invoke `.result` to
trigger a save of the result set, but don't call `.format!` to avoid
(re)generating the HTML output with every run. The final output will
still be written once the main unit test run completes.

This significantly speeds up the integration tests, that take about 1/3
less time to complete when not generating the intermediate output.

Commands executed during integration testing are executed in a separate
process and thus generate a new result set for each command. To avoid
that these results override each other, they need to have a unique
`command_name`. Derive this name from the test class/name and the index
of the command inside that test, resulting in identifiers like
`IntegrationCommandTests#test_prefix.1 brew --prefix`.

Also replaces `TEST_TMPDIR` in the arguments with `"@TMPDIR@"` to get a
cleaner command identifier that is independent of the temporary
directory that changes with every run.

Simplify running a single test (or even a single method from a single
test), which is useful when developing or debugging a test. Instead of
`brew test TEST=test_diagnostic.rb TESTOPTS=--name=test_check_DYLD_vars`
it is now possible to run `brew tests --only=diagnostic/check_DYLD_vars`
to get the same effect. Similarly, `brew tests --only=diagnostic` maps
to `brew test TEST=test_diagnostic.rb`.

This parameter is printed by every `brew tests` run and feeding it back
into the test suite allows to get an identical run. Make it easier to
do that by accepting the argument as it is printed during `brew tests`.

This requires a slight adjustment to named-argument passing as the
number that follows `--seed` is also seen as a named argument, but we
usually only want to pass `TEST=<something>` and `TESTOPTS=<something>`.

The filter for `vendor/bundle/` is useless because this directory is
located in `Homebrew/test/` and that one is already filtered. Moreover,
SimpleCov already loads the `bundler_filter` profile (that installs
basically the same filter) in its default configuration.

This came up in https://github.com/Homebrew/homebrew-emacs/pull/158#issuecomment-172031003;  `install_metafiles` is passed the current directory, which can be changed during installation by `Dir.chdir`.

There may be cases where the metafiles are in a subdirectory, but my
guess is those are rare and this is brittle and undocumented behavior
anyway.

Xcode can only provide autotools if it is installed, thus check that
first. Skipping this check will try to compare a `nil` Xcode version to
4.3, the first version of Xcode to not provide autotools.
