Fixed compiler warnings

Fixed bug in ma_dbug.c that gave valgrind warning (only relevant when using --debug)
Fixed bug in blob logging (Fixes valgrind warning)
maria_getint() -> maria_data_on_page()


mysys/safemalloc.c:
  Added debug function to print out where a piece of memory was allocated
sql/opt_range.cc:
  Remove DBUG_PRINT of unitailized memory
storage/maria/ma_blockrec.c:
  Fixed bug in blob logging
storage/maria/ma_check.c:
  Fixed compiler warning
storage/maria/ma_dbug.c:
  Added missed end++; Caused usage of unitialized memory for nullable keys that was not NULL
storage/maria/ma_delete.c:
  maria_getint() -> maria_data_on_page()
storage/maria/ma_init.c:
  Added header file to get rid of warning
storage/maria/ma_key.c:
  More debugging
storage/maria/ma_loghandler.c:
  Removed some wrong ';' to get rid of compiler errors when compiling without debugging
  Indentation fixes
  Removed not needed 'break's
  Fixed some compiler warnings
  Added code to detect logging of unitialized memory
storage/maria/ma_page.c:
  maria_getint() -> maria_data_on_page()
  Clear rest of index page before writing when used with valgrind
  (Fixes warning of writing pages with unitialized data)
storage/maria/ma_range.c:
  maria_getint() -> maria_data_on_page()
storage/maria/ma_rt_index.c:
  maria_getint() -> maria_data_on_page()
storage/maria/ma_rt_index.h:
  maria_getint() -> maria_data_on_page()
storage/maria/ma_rt_key.c:
  maria_getint() -> maria_data_on_page()
storage/maria/ma_rt_split.c:
  maria_getint() -> maria_data_on_page()
storage/maria/ma_search.c:
  maria_getint() -> maria_data_on_page()
storage/maria/ma_test1.c:
  Fixed compiler warning
