  1. Fix nasa#950, race condition in control request 

    Because the process of handling a control request involves
calling other subsystems, the ES lock needs to be released.
However, this also means that the app record can change state
for other reasons, such as the app self-exiting at the same
time.

To avoid this possibility, process in two phases:

First assemble a list of tasks that have timed out
and need to be cleaned up, while ES is locked.

Next actually perform the cleanup, while ES is unlocked.
In areas during cleanup that need to update the ES global,
the lock is locally re-acquired and released.

  2. Fix nasa#173, refactor app and lib loading procedure 

    Reorganize the global data structures for apps and
libraries into components that can be shared between
the two concepts.

Break up the monolithic AppCreate and LoadLibrary
functions and have these call subroutines that
operate on the common components.

  3. Fix nasa#28, Provide Library API similar to App API 

    Allows the existing "CFE_ES_AppInfo_t" structure to be extended to
libraries as well as applications by introducing a new value (3)
for the Type field.

Allows Libraries to be queried via API calls similar to App API.

Also extends the Query All/Query One commands to operate on
Libraries or Applications.
