- Store in the tab if a bottle was poured for the build.
- Add an additional line of output to `brew info` outputting whether
  the formula was built from source or poured from a bottle.

This makes it requirable before superenv becomes active.

I understand how this works now, and it is definitely necessary.

Reader methods for specific checksum types have been absent from the
Formula class for some time, so there isn't any reason to expose them in
SoftwareSpec, either.

Thus, these methods now only act as setters, and #checksum should be
used to access the constructed Checksum object.

git clean -f is not enough. Needs `-d` somtimes to

Under certain conditions, `brew update` will show doubles. It's a rare
edge-case, but if you have a tap where the name of the formula is identical
with the name of the insalled file, then you see output like this:

    ==> Updated Formulae
    aalib				   ssh-copy-id
    casperjs				   sshuttle
    jack				   telemachus/anytap/brew-any-tap
    mogenerator				   telemachus/anytap/brew-any-tap

I believe this should fix that.

The existing case-statement with nested if-statements is gross and hard
to extend. Replacing it with a priority queue simplifies the logic and
makes it very easy to add new compilers to the fails_with system, which
we will likely want to do in the future.

The original constraints that led to using a custom collection rather
than Array or Set here no longer exist, so let's avoid the pointless
abstraction here.

Given the current state of OS X compilers, the original fails_with
behavior is becoming less useful, mostly resulting in build failures
each time the compiler is updated. So make the following changes:

When a build is specified, we retain the old behavior: switch compilers
if the available compiler is <= the build, don't switch if it is > the
build.

When no build is specified, unconditionally switch compilers, and don't
output the advice message. This allows us to mark formulae as
perpetually failing, avoiding the need to update formulae each time a
new compiler build is made available.

As a bonus, this makes the logic much easier to reason about.

Currently `brew tap` only works on repos with 'homebrew-' in their name.

This version tries the repo name as is and then falls back to try
'homebrew-repo' only if that fails.

I've also tweaked the regex  in tap_args to allow '-' in repo names. The
previous regex required a match on \w. This made it impossible for people
to tap repos with names like 'username/why-not'.

IO#read does not raise EOFError, it just returns an empty string for
each call after it consumes the underlying file or stream.

This module is going to be refactored and the begin/rescue is going to
be removed anyway.

This has two parts:

1. Bottles are temporarily relocated on bottling and tested if that is
sufficient for them to contain no longer reference the prefix or
cellar. If so, they are marked as relocatable.
2. On installation if bottles are marked as relocatable they will be
relocated using install_name_tool to the current prefix and cellar.
