Bug#11763507 - 56224: FUNCTION NAME IS CASE-SENSITIVE

Analysis:
-------------------------------
According to the Manual
(http://dev.mysql.com/doc/refman/5.1/en/identifier-case-sensitivity.html):
"Column, index, stored routine, and event names are not case sensitive on any
platform, nor are column aliases."

In other words, 'lower_case_table_names' does not affect the behaviour of 
those identifiers.

On the other hand, trigger names are case sensitive on some platforms,
and case insensitive on others. 'lower_case_table_names' does not affect
the behaviour of trigger names either.

The bug was that SHOW statements did case sensitive comparison
for stored procedure / stored function / event names.

Fix:
Modified the code so that comparison in case insensitive for routines 
and events for "SHOW" operation.
