[Wenchao Xia <xiawenc@linux.vnet.ibm.com>]

  This patch intrudce libqblock API, libqblock-test is used as a test case.
make libqblock-test at root diretory could make it build. Test it with
./libqblock/libqblock-test [FILE] [BACKINGFILE]

V2:
  Format specific options were brought to API surface.
  All option were changed to enum type instead of string.
  ALL flags used were defined in libqblock.h.

V3:
  Introduced broker, which was used for each thread, now it is used only to
handle errors.
  Introduced AIO, it is based on qemu's aio implemetion.
  Balanced the structure folder depth and extension-bility, now parameters
are classed into two kinds: location and formats.
  Using reserved bytes in structure to make ABI code simpler.
