After discussion with PeterG and Serge, a new coercibility

sql/item_strfunc.cc:
Use on stack variable for Item_str_func::val() instead of str_value.
This makes it safe to use str_value inside the Item's val function.
Cleaned up LEFT() usage, thanks to the above change
sql/item_sum.cc:
Indentation cleanups
sql/protocol.cc:
Added missing cast
sql/sql_acl.cc:
Indentatin cleanups.
Added missing cast
Simple optimization of get_sort()
sql/sql_select.cc:
Don't use 'ref' to search on text field that is not of type BINARY (use 'range' instead).
The reson is that for 'ref' we use 'index_next_same' to read the next possible row.
For text fields, rows in a ref may not come in order, like for 'x', 'x\t' 'x ' (stored in this order) which causes a search for 'column='x ' to fail
sql/tztime.cc:
Simple cleanup
strings/ctype-bin.c:
Comment fixes
strings/ctype-mb.c:
Changed variable names for arguments

mysql-test/r/ctype_utf8.result:
