unnecessarily when _M_rep() == &_S_empty_rep() and __new_size
== capacity() (== 0): is ok to just leave everything unchanged.

* include/ext/bitmap_allocator.h: Change unsigned int -> size_t: this
makes the code 64-bit correct and also fixes (together with using at
the beginning a bitmap 2 * size_t bytes wide) alignment issues: now
8 is guaranteed, easily tunable to 16 via _BALLOC_ALIGN_BYTES.
Fix pthread-rope7.cc fail by nulling out __mini_vector<> destructor.
* src/bitmap_allocator.cc: Change to size_t.
* config/linker-map.gnu: Adjust.
