Implemented dynamic allocation for packing buffers.

Browse Source 
Details:
- Replaced the old memory allocator, which was based on statically-
  allocated arrays, with one based on a new internal pool_t type, which,
  combined with a new bli_pool_*() API, provides a new abstract data
  type that implements the same memory pool functionality but with blocks
  from the heap (ie: malloc() or equivalent). Hiding the details of the
  pool in a separate API also allows for a much simpler bli_mem.c family
  of functions.
- Added a new internal header, bli_config_macro_defs.h, which enables
  sane defaults for the values previously found in bli_config. Those
  values can be overridden by #defining them in bli_config.h the same
  way kernel defaults can be overridden in bli_kernel.h. This file most
  resembles what was previously a typical configuration's bli_config.h.
- Added a new configuration macro, BLIS_POOL_ADDR_ALIGN_SIZE, which
  defaults to BLIS_PAGE_SIZE, to specify the alignment of individual
  blocks in the memory pool. Also added a corresponding query routine to
  the bli_info API.
- Deprecated (once again) the micro-panel alignment feature. Upon further
  reflection, it seems that the goal of more predictable L1 cache
  replacement behavior is outweighed by the harm caused by non-contiguous
  micro-panels when k % kc != 0. I honestly don't think anyone will even
  miss this feature.
- Changed bli_ukr_get_funcs() and bli_ukr_get_ref_funcs() to call
  bli_cntl_init() instead of bli_init().
- Removed query functions from bli_info.c that are no longer applicable
  given the dynamic memory allocator.
- Removed unnecessary definitions from configurations' bli_config.h files,
  which are now pleasantly sparse.
- Fixed incorrect flop counts in addv, subv, scal2v, scal2m testsuite
  modules. Thanks to Devangi Parikh for pointing out these
  miscalculations.
- Comment, whitespace changes.
