Fixes to get valgrind to work with jemalloc

- Added MALLOC_LIBRARY variable to hold name of malloc library
- Back ported valgrind related fixes from jemalloc 3.4.1 to the included jemalloc 3.3.1
- Renamed bitmap_init() and bitmap_free() to my_bitmap_init() and my_bitmap_free() to avoid clash with jemalloc 3.4.1
- Use option --soname-synonyms=somalloc=NON to valgrind when using jemalloc
- Show version related variables in mysqld --help
  -- Added SHOW_VALUE_IN_HELP marker

Increased back_log to 150 as the original value was a bit too small
