Lots of spurious xmlrpc messages seen in logs in artdaq v3_5_0 system
I see lots of messages like the following in the artdaq process logs in an artdaq-v3_5_0-based system at protoDUNE:
Back from xmlrpc_string_new_lp
value_string constructor exiting
value_string constructor entered
Going to call xmlrpc_string_new_lp
length = 6, value = Booted
I suspect that these messages are going into the PMT log in artdaq-demo systems.
Can we disable these somehow?

- Go back to a previous version of xmlrpc_c, making sure that it compiles with e19 and c7
- Move to a newer version of xmlrpc_c, assuming that the problem has been fixed
- Patch the current version to make sure these printouts are removed

I have found the problem in the build-framework-xmlrpc-c-ssi-build repository: there were two patch files for this issue, but only one was being applied. Since this is already a distributed product, the best way forward is probably to add an a to the version and make a new set of tarballs. The next artdaq release would then use that version of xmlrpc_c.

Eric, thanks for the patched version of xmlrpc_c (v1_51_03a). Tests with the updated version of the demo v3_06_00 confirm that the messages are gone.
The timing of this is nice. This morning, Phil Rodrigues (protoDUNE) asked about getting rid of these messages, and it was nice to be able to report that a fix can be deployed at a convenient time.
