Bug#28478 - Improper key_cache_block_size corrupts MyISAM tables
Setting a key_cache_block_size which is not a power of 2
could corrupt MyISAM tables.
A couple of computations in the key cache code use bit
operations which do only work if key_cache_block_size
is a power of 2.
Replaced bit operations by arithmetic operations
to make key cache able to handle block sizes that are
not a power of 2.

Bug#28478 - Improper key_cache_block_size corrupts MyISAM tables
Removed element 'key_cache_shift' from KEY_CACHE after
the changes in mf_keycache.c made it unused.
