BINARY fields to length > 255.

Fixed test failure under heavy load, in case truncate table is slow.

the first query is not running while we are doing wait queries on

Discovered a bug while working with backup. Since it is possible to execute a statement in a pre/post statment clause that can return a result, we need to test for that and free it.

statement.

c++config.h now has the following code:
// For example, <windows.h> is known to #define min and max as macros...
#undef min
#undef max

So, our defines in my_global.h are undefined when <new> header
is included.

Move definitions of min()/max() to the end of my_global.h.

Invaldating a subset of a sufficiently large query cache can take a long time.
During this time the server is efficiently frozen and no other operation can
be executed. This patch addresses this problem by setting a time limit on
how long time a dictionary access request can take before giving up on the 
attempt. This patch does not work for query cache invalidations issued by
DROP, ALTER or RENAME TABLE operations.
