Changed SHOW_FUNC variabels that don't return SHOW_ARRAY to SHOW_SIMPLE_FUNC.

This allows us to avoid calculating variables (including those involving mutex) that doesn't match the given
wildcard in SHOW STATUS LIKE '...'
Removed all references to active_mi that could cause problems for multi-source replication.
