Clarify that brew does not provide XQuartz

Reword the `X11Dependency` error message so that it is clear that an installer
must be downloaded.

Ref #14851.
Tighten post-install checks

 - Avoid ENOTDIR by ensuring that the directories we are checking are
   actually directories.
 - DRY up the check_PATH method; paths are already available via the
   global ORIGINAL_PATHS.

Tab: provide an interface similar to BuildOptions

Eventually a common interface could be factored out into a module, but
for now this will suffice.

Install receipt housekeeping

- Since using opt_prefix means we can find receipts for keg-only
  formulae, try it first and fall back on using linked_keg.
- Make the tab filename a constant instead of duplicating the string
  everywhere.
- Address a couple of other things that need cleanup.

Provide a common interface for Dependency and Requirement

Introduce a new Dependable module that provides useful interrogation
methods for Dependency and Requirement. These methods are mapped to
dependency tags in formula (:build, :optional, and :recommended).

Previously only Dependency objects recorded tags; this allows
Requirements to do the same.

Move Requirement subclasses to a separate file.
Formula#recursive_dependencies

This behaves like recursive_deps, but the resulting list consists of
Dependency objects instead of Formula objects. The list maintains the
installable order property of recursive_deps.

While in the area, add some comments clarifying the purpose of related
methods.

FormulaInstaller: disambiguate show_header usage

show_header should default to false (we don't want to display it in the
case of installing a single formula without dependencies), but it only
worked this way by accident.

The assignment "show_header = true" creates a local variable named
show_header, and in the case where needed_deps is empty and this
assignment is not actually executed, the latter usage evaluates the
local variable instead of calling the method.

FormulaInstaller: implement installation locks

FormulaInstaller now attempts to take a lock on a "foo.brewing" file for
the formula and all of its dependencies before attempting installation.

The lock is an advisory lock implemented using flock(), and as such it
only locks out other processes that attempt to take the lock. It also
means that it is never necessary to manually remove the lock file,
because the lock is not enforced by I/O.

`brew uninstall` learns to respect the lock as well, so that kegs in the
dependency tree of foo can't be removed when another process is
installing foo.
