Subject: Fixed compiler warnings detected by option -Wshadow and -Wunused: -
 Removed not used variables and functions - Added #ifdef around code that is
 not used - Renamed variables and functions to avoid conflicts - Removed some
 not used arguments

Fixed some class/struct warnings in ndb
Added define IS_LONGDATA() to simplify code in libmysql.c

I did run gcov on the changes and added 'purecov' comments on almost all lines that was not just variable name changes
