[PATCH] base-small: introduce the CONFIG_BASE_SMALL flag

This patch series introduced a new pair of CONFIG_EMBEDDED options call
CONFIG_BASE_FULL/CONFIG_BASE_SMALL.  Disabling CONFIG_BASE_FULL sets the
boolean CONFIG_BASE_SMALL to 1 and it is used to shrink a number of core data
structures.  The space savings for the current batch is around 14k.

This patch:

Add CONFIG_BASE_SMALL for miscellaneous core size that don't warrant
their own options. Example users to follow.
