Provides API to make it easy for modules to implement plugins.
The plugins tool allows a module to allow other modules (and themes!) to
provide plugins which provide some kind of functionality or some kind of task.
For example, in Encrypt there are several types of plugins: encryption methods
and key providers. Each plugin is represented by a .inc file, and the
functionality they offer can differ wildly.
A module which uses plugins can implement a hook describing the plugin (which is
not necessary, as defaults will be filled in) and then calls a function
which loads either all the known plugins (used for listing/choosing) or a
specific plugin (used when it's known which plugin is needed). From the
perspective of the plugin system, a plugin is a packet of data, usually some
printable info and a list of callbacks. It is up to the module implementing
plugins to determine what that info means and what the callbacks do.
A module which implements plugins must first implement the
hook_plugin_directory function, which simply tells the system
which plugins are supported and what directory to look in. Each plugin will then
be in a separate .inc file in the directory supplied. The .inc file will contain
a specially named hook which returns the data necessary to implement the plugin.
