This is initialized in #initialize.

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.

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.

Closes Homebrew/homebrew#18374.

These are redefined later for use in the bottle DSL.

Currently we handle options in several ways, and it is hard to remember
what code needs an option string ("--foo"), what needs only the name
("foo") and what needs an Option object.

Now that Option objects can act as strings and be converted to JSON, we
can start using them instead of passing around strings between Formula
objects, Tab objects, and ARGV-style arrays.

The Options class is a special collection that can be queried for the
inclusion of options in any form: '--foo', 'foo', or Option.new("foo").

We want to be able to use Option objects in place of strings and have
this be transparent. Defining to_str means that methods like
Kernel#system and Kernel#exec will be able to perform an implicit
conversion.

While at it, make it use class methods instead; no reason to instantiate
an object for this.

Eventually there should be some functional tests for the individual
strategies as well.

Simplify access to the different forms of a formula's build options by
making options into real objects rather than strings, and expose both
the 'name' and 'flag' form.
