Problem:
if a user was granted privileges on database "d1",
it also was able to act on "D1" (i.e. in upper case),
even on Unix with case sensitive file system.
Fix:
Initialize grant hash to use binary comparison
if lower_case_file_system is not set (on most unixes),
and case insensitive comparison otherwise (Windows, MacOSX).
sql/sql_acl.cc:
Initialize hash to use binary comparison with case sensitive FS.
