BUG#21915: Changing limits of table_cache when setting max_connections

Browse Source 
If the user has specified --max-connections=N or --table-open-cache=M
options to the server, a warning could be given that some values were
recalculated, and table-open-cache could be assigned greater value.

Note that both warning and increase of table-open-cache were totally
harmless.

This patch fixes recalculation code to ensure that table-open-cache will
be never increased automatically and that a warning will be given only if
some values had to be decreased due to operating system limits.

No test case is provided because we neither can't predict nor control
operating system limits for maximal number of open files.
