This delta imposes two major changes on the C++ hierarchy:
  - adds autoconf, automake, libtool support
  - makes the hierarchy flatter and renames a few files (e.g., Queue.h,
  Queue.cpp) that appeared twice, once under client/ and again under broker/.

In the process, I've changed many #include directives, mostly
to remove a qpid/ or qpid/framing/ prefix from the file name argument.
Although most changes were to .cpp and .h files under qpid/cpp/, there
were also several to template files under qpid/gentools, and even one
to CppGenerator.java.

Nearly all files are moved to a new position in the hierarchy.
The new hierarchy looks like this:

  src               # this is the new home of qpidd.cpp
  tests             # all tests are here.  See Makefile.am.
  gen               # As before, all generated files go here.
  lib               # This is just a container for the 3 lib dirs:
  lib/client
  lib/broker
  lib/common
  lib/common/framing
  lib/common/sys
  lib/common/sys/posix
  lib/common/sys/apr
  build-aux
  m4
