This patch modifies the multiplexer logic to support full recursive
multiplexation, unlike the old version which only flattened the
multiplexed nodes. This allows greater flexibility.

Additionally it removes the !join flag and inverts the logic to use !mux
instead. By default leaves are not multiplexed and all are part of the
current params. Users can specify exact nodes which get multiplexed by
using !mux keyword.

Multiplexed nodes affects heavily the tree structure and users should
see i in the tree view. This patch makes "multiplex" nodes visible.

In the documentation, explain that the test API is everything
under avocado module, but excludes avocado.core.

Also, Avocado works with plugins, so let's talk about it,
in the introduction too.

Plugins improve list view [v2]

This is how I believe *plugin* dependencies should be handled. If
something that a plugin requires is not present, it simply fails to
load.

Pick the information collected while loading plugins to display to the
user clearly why some of their plugins are not working.

Changes from v1:

* Instead of guessing the plugin disable cause, use a more generic but
  accurate description.  The description chosen is to simply say that
  the plugin was disabled during configuration (`configure()`), which
  is often done, but not limited to, missing dependencies.
* Changed the presentation from having colored `Enabled` or `Disabled`
  at the RHS of the plugin description to a single colored header.
* Increased one space in the formatting string (`format_str`)

Store failed plugins instead of logging them to stderr.  That will
allow us to give better information to the user as of why a given
plugin was disabled.

Changes from v1:
 * Dropped the use of FailedPlugin in favor of a simpler (name,
   reason) tuple.
 * Catch a single, and more broad `Exception` since `ImportError`s
   will also be caught and treated the same way.

Avocado shouldn't crash, it should only notify user about the failure.
This patch modifies the existing mux exceptions to reflect this rule and
adds new exception handler for incorrect yaml file.

This reverts commit 71d47611.

The idea in the mentioned commit were sent to the upstream mailing

maintain support in Avocado for something that will never make into
GDB itself.
