daqd_shmem is similar to a standiop.  However it reads data from one combined shared memory segment, does not require a timer or adc card.

Updates to the fe_stream_test to put data in the proper places.

Additional test scripts and commands to help manipulate and introspect mbuf memory buffers.
src/drv/mbuf/mbuf_probe
src/zmq_stream/scripts/dump_zmq_core_structs.py

Added a zmq_recv command to receive data from a zmq stream and publish it to a local mbuf.

Adding a new c userspace interface to the mbuf shared memory.

With flex <= 2.5 yyin/yyout are pointers, with 2.6+ they are member
objects of the generated lexer.  Adapt the build system to detect which
is in use, and the code to work with both variants in flex.

Among other items allows daqd to build on both Debian 8 & 9.

This is to give us integration with modern tooling, out of tree builds, and easier packaging.

This is not yet ready for production.
