Injecting more "const" declarations into code which does not change
pointed data.
I ran gcc -Wcast-qual on storage/maria, this identified un-needed casts,
a couple of functions which said they had a const parameter though
they changed the pointed content! This is fixed here. Some suspicious
places receive a comment.
The original intention of running -Wcast-qual was to find what code
changes R-tree keys: I added const words, but hidden casts
like those of int2store (casts target to (uint16*)) removed const
checking; -Wcast-qual helped find those hidden casts.
Log handler does not change the content pointed by LEX_STRING::str it
receives, so we now use a struct which has a const inside, to emphasize
this and be able to pass "const uchar*" buffers to log handler
without fear of their content being changed by it.
One-line fix for a merge glitch (when merging from MyISAM).
include/m_string.h:
As Maria's log handler uses LEX_STRING but never changes the content
pointed by LEX_STRING::str, and assigns uchar* into this member most
of the time, we introduce a new struct LEX_CUSTRING
(C const U unsigned) for the log handler.
include/my_global.h:
In macros which read pointed content: use const pointers so that
gcc -Wcast-qual does not warn about casting a const pointer to non-const.

In macros which read pointed content: use const pointers so that
gcc -Wcast-qual does not warn about casting a const pointer to non-const.
