confdefs: Add declaration for unlimited objects.

Adds to confdefs a way to specify rtems_resource_unlimited for classic and
posix objects using a new macro CONFIGURE_OBJECTS_UNLIMITED.
Use CONFIGURE_OBJECTS_ALLOCATION_SIZE to declare the allocation size for
extending the set of objects at runtime. Updates the unlimited sample
to demonstrate how to use the new macros. Also adds new documentation in
the C User's Manual regarding configuring with unlimited objects.
