123666299e Bug#29856: Insufficient buffer space led to a server crash. 
The subst_spvars function is used to create query string with SP variables 
substituted with their values. This string is used later for the binary log
and for the query cache. The problem is that the
query_cache_send_result_to_client function requires some additional space
after the query to store database name and query cache flags. This 
space wasn't reserved by the subst_spvars function which led to a memory
corruption and crash.

Now the subst_spvars function reserves additional space for the query cache.

8ee7e48de8 Bug#28249 Query Cache returns wrong result with concurrent insert / certain lock 
A race condition in the integration between MyISAM and the query cache code 
caused the query cache to fail to invalidate itself on concurrently inserted
data.

This patch fix this problem by using the existing handler interface which, upon
each statement cache attempt, compare the size of the table as viewed from the 
cache writing thread and with any snap shot of the global table state. If the
two sizes are different the global table size is unknown and the current
statement can't be cached.

b89e4f9ef2 Bug #29053 SQL_CACHE in UNION causes non-deterministic functions to be cached 
Changed code to enforce that SQL_CACHE only in the first SELECT is used to turn on caching(as documented), but any SQL_NO_CACHE will turn off caching (not documented, but a useful behaviour, especially for machine generated queries). Added test cases to explicitly test the documented caching behaviour and test cases for the reported bug.

5198354584 Bug#20045: Server crash on INSERT ... SELECT ... FROM non-mergeable view 
The regression is caused by the fix for bug 14767. When INSERT ... SELECT
used a view in the SELECT list that was not inlined, and there was an 
active transaction, the server could crash in Query_cache::invalidate.

On INSERT ... SELECT only the table being inserted into is invalidated.
Thus views that can't be inlined are skipped from invalidation.

The bug manifests itself in two ways so there is 2 test cases.
One checks that the only the table being inserted into is invalidated.
And the second one checks that there is no crash on INSERT ... SELECT.
