+TimestampedBuffer.cpp: move the include of math.h to the top of the file which is where most people would expect it to be.  The patch comes from a Fedora RPM source package via Simon Lewis, who suggested that without it gcc6 had trouble with the file (the nature of the problem is not known by the FFADO project at this time).  Earlier versions of gcc (for example, 4.8.2) had no trouble compiling this file without any math.h include, so the issue that some have seen with gcc6 must be due to math.h being removed from some other system-level include file at some point.

+configrom: there is no obvious reason why a space should be added to the end of the vendor and model strings returned from the interface.  Retain the explicit null termination of these strings to cover for the case where an interface may not return any null bytes.  Also fix indentation associated with the null termination code.  The issue with the trailing space was noticed and reported by Nils Philippsen: its presence broke a test in the saffire_dice mixer python code.
