Closes #15 Remove kernel patch changing cpu_up to EXPORT_SYMBOL
Update README in patches/linux-4.19-cs for change
Remove symbols from patched kernel in src/drv/ExtraSymbols.symvers
Add parameter in GNUmakefile to build will reference Module.symvers from kernel

Removing some unused diagnostic messages that could overflow under large dcu counts and corrupt the stack

The code had been inserting a dcuid '0' into the output headers, make it just skip the model completely in the output.
Also removed a duplicate function to parse a comma delimited list of integers.

Disable CONFIG_DRM_AST flag so kernel uses 'nomodeset' on AST VGA chips
which prevents interrupts causing long IOP cycles on newer front-ends
(and removes need for nomodeset as kernel boot parameter)
Update README in patches/linux-4.19-cs for these changes

Update the test code to allow specifying specific dcus.
Update local_dc to fail if it cannot determine the model rate.

* Increases the DAQ_TRANSIT_MAX_DCU to 256
* Updates the tests of daqd/nds to run with more dcus and sample more channels
* Fixes a spurious failure in the edcu test to keep tests passing

This fixes a bug in which arbitrary waveform excitations failed, with awgtpman reporting the data was too far in the future

Allow spurious failures.  Just require that we exceed the number of successful connections that used to be in a 32 bit bit mask.

The FRAMECPP_VERSION_NUMBER is not properly defined in v2.7.0.  If it is empty, assume version 2.7.0.

Allow spurious failures.  Just require that we exceed the number of successful connections that used to be in a 32 bit bit mask.

This addresses the issue by expanding the size of the bitmask.
* Replace the 'int' bitmask with a generic structure.  This allows the
type system to help us find all the places it is used.
* Replace direct bitmask manipulation with member functions to increase
local readability.
* Allow the new bitmask structure to have an increased capacity that can
be set (at compile time).
* Add unit tests to new bitmask code.
* Add test code to look at nds1 load.

in model start/kill scripts.  No longer needed as now have SDF.

compile option not used in a normal system.

Use transport-independent RPC package (tirpc) if available,
otherwise use RPC headers if still available.
Mostly for non-Debian compiles, as Debian asserts non-default
flag in glibc to retain the old RPC support

Removed the edcuFileStatus and edcu_ini_fckrs from the daqd object.

external dcu model.

Casting where needed.
Adding forward declarations.
Adding missing includes.
Const/Volatile corrections.
Adding missing return types.

* Removing makefile/autotools build pieces.
* Removing non-daqd_shmem specific files
* Removed some of the #ifdef soup

The test will now run the whole test end to end, instead of pausing for
manual debugging.

Updated the help text and the test to use the correct notifier for the
end/duration of the test (-stop).

Added an 'analyze' mode to mbuf_probe to allow it to dump data in real
time with some basic data extracted.

Extended tests with new synthentic generators to help highlight issues.

It appears that there is a byte swap issue with 16bit ints.  Committing
code before looking into the daqd code.

mbuf_probe is a diagnostic tool to manipulate (list,
create, copy, delete) mbufs.  This change makes it so
that you no longer need to read the code to figure out
how to use the tool.

* Moving a size and data type information from daq/channels.h to
include/daq_data_types.h.
* Extending standalone_edc to use DBR_TIME* to look for late data.
* Updating the stream generators to handle more data types.

You can get into a situation where multiple disconnect events happen
w/o connection events.  This makes it look like the code cannot count
connected channels.  Only change the counts when we have a change from
the current state.

Introduce fixed sized buffers and split the iteration of the channel
list into stages.  This bounds the memory use of the each connected
client.

This allows disconnected channel lists to be extracted from the edc.
