This prevents `brew` self-calls from interacting with the stickiness of
HOMEBREW_NO_ANALYTICS being persisted to the brew repo and accidentally
disabling analytics permanently when it should have been for just one run,
while restoring the stickiness of an explicit user-supplied
HOMEBREW_NO_ANALYTICS.

DO not invoke git config because HOMEBREW_NO_ANALYTICS, otherwise
it will disable analytics for everyone when running `brew update`
in following manners:
 * `brew update` will set HOMEBREW_NO_ANALYTICS because the absence of
   `homebrew.analyticsmessage`
 * `brew update-report` will set `homebrew.analyticsdisabled` because of
    HOMEBREW_NO_ANALYTICS.

Also reduce file IO.

Provide a single command that can be run to disable analytics, run it if
`HOMEBREW_NO_ANALYTICS` is ever set and remove the user UUID file in
that case too.

Make sure that users are notified on the first run of `brew update`
after we enabled analytics about how it works and how to opt-out. This
will be shown to all users who have not already seen this message from
`brew update` or through a new Homebrew installation.

Sometimes they are in e.g. libexec but there's no real reason to assume
they are anywhere; we want to relocate them regardless.

Closes #118.

This will be expanded to a full expat dependency on Tiger alone.

Fixes mistydemeo/tigerbrew#30.

Setting -mcpu and -mtune on Tiger with gcc-4.2 exposes a bug in one of the
system headers, causing certain builds to fail. This can be fixed by
adding -faltivec to CFLAGS.

The new stage() signature introduced by #66 breaks back-compatibility
under Ruby 1.8.7. This fixes it by switching back to a one-argument
block signature and using a new class to wrap both the Resource and
Mktemp info for the staging context, in a signature-back-compatible
way.

Addresses homebrew/homebrew-core#529.

Closes #135.

We want to always avoid merge commits being committed to Homebrew so
this feels like a better fit.

Make multiple replacements if using the block form.

It simplifies the number of commands and it's now an officially
supported command again.

Closes #119.

Since switching from `system` to `Utils.popen_read` we no longer need to
suppress Ruby's output of `Syntax OK` to `$stdout`.

Previously, syntax warnings were printed, but didn't cause `readall` to
exit with a non-zero exit code. Now they do, making it easier to catch
accidentally introduced syntax warnings in the test bot.

The current one returns a 404.

Reorders the PR submission steps so `brew audit` is done after `brew install`,
so it can pick up issues with the installed formula, like non-executable stuff
in `bin/`. Matches the `test-bot` process better.

Minor style changes, including consistently using periods at the end of list items
which are complete imperative sentences.

This collects all violations for each formula in a single place, instead
of doing `brew style` outputs for all formulae first, and then the other
audit checks.

This version is never wanted at this point and it will help Homebrew
Cask deal with the annoying errors that result from having this version
still around (some which I've already help users debug).

Someone else has been sending weird data to ours and it has bad initial
test data so let's roll it before we ship it to everyone on Saturday.
