In order to allow kegs built with the same version but differing formula
revisions to coexist, we must encode the revision as part of the keg's
name. This is necessary to actually perform an upgrade, as we cannot
upgrade a keg in-place, and temporarily moving it pending the result of
the upgrade is error-prone and potentially slow.
To accomplish this, we introduce a new Formula#pkg_version method that
concatenates the active_spec version with the formula revision. An
exception is made for a formula that has no revision: the tag is
omitted. This preserves compatibility with existing installations.
It is useful to be able to prompt upgrades in response to events other
than a version update; for example, when a dependency is updated and its
library version changes, dependents need to be rebuilt to link against
the new library.
Currently we cannot do this automatically, which means a flood of
tickets whenever the library version of a popular library changes.
To address this, we need to track an additional piece of metadata, the
"revision" of the formula, which can be incremented when appropriate to
prompt an upgrade. It can then be reset to zero when the next version
change occurs.

There are two ways of outputting bright ANSI colors to the terminal - the ANSI codes 30-37 plus a bold code (most terminals render bold text with brighter colors, by convention), or the widely supported aixterm codes 90-97.
Although the aixterm codes are more precise (disambiguating bold font from bright color), the ANSI bold+green enables compatibility with the popular [Solarized](https://github.com/altercation/solarized) color theme, which reassigns the "bright green" codepoint to a shade of gray.

I'd still like to make this change, but at least for now the initializer
requires ignore_deps to be set correctly.
This reverts commit 881a8855b944fa9bd7dfd598bb9197f79f7a13f0.
Sometimes there may be intermittent failures with hosts that work if
immediately retried. Let's allow a single retry in this case with the
--retry flag. This also behaves nicely with the --force flag.
