Added MY_CS_NONASCII marker for character sets that are not compatible with latin1 for characters 0x00-0x7f
This allows us to skip and speed up some very common character converts that MySQL is doing when sending data to the client
and this gives us a nice speed increase for most queries that uses only characters in the range 0x00-0x7f.

This code is based on Alexander Barkov's code that he has done in MySQL 6.0

Changed default thread stack to 288K to get better memory missalignment between stacks of different threads (should speed up things) and to get a bit extra safety.
In maria_open(), don't allocate big arrays on stack as this may lead to stack overflow.
This fixes a valgrind warning detected by buildbot
