awgtpman: interface backwards compatibility changes

See merge request !371

In response to comments by Patrick

awgtpman: client interface will now detect and use older RPC interfaces

See merge request cds/advligorts!369

RPC results need to be cleared before calling an RPC function.

Version 4.0.1 and earlier had 4 testpoint interfaces instead of two.
This code autodetects which interfaces are used by awg
and switches to the appropriate interface

 * daq_data_types.h includes portableInline.h, so have cmake install that as well.

RTS: ADC read 'max_loops' reset per card

See merge request cds/advligorts!364

Previously in the adc read function, a slow card would lead to 'max_loops' dropping to 1 and staying there for future cards.
Fast ADCs read after slow ADCs would not have the output data properly decimated.

Merge branch 'perldaq_back_in' of https://git.ligo.org/erik.vonreis/advligorts into build_reorg_follow_on

Modify makefile to work with DKMS.  Apparently DKMS silently fails if you try to rearrange the source tree.

Build is now back to being in-place, but properly cleans up!

More warning fixes

Adding gaussian noise part

See merge request cds/advligorts!354

Makefiles now honor symvers file locations if they are already specified in the environment.
This could cause problems if variables are unkowingly left defined.
A better option would be to override the variables on the command line
Variable names are changed to make it easier to derive them from module names.
