This commit attempts to smooth some wrinkles impacting any future libprocps user exploitation. The 2 problems relate exclusively to our XTRA_PROCPS_DEBUG provision. 1. The 'xtra-procps-debug.h' header had an include for 'procps-private.h', which was not an installed header. So the STRINGIFY macros will now be embedded directly. 2. Each of the new api headers referenced '<proc/...>' rather than '<procps/...>' for the debugging #include. So, we must drop that prefix in favor of a quoted file name so that debugging builds work regardless of where that 'xtra-procps-debug.h' header happens to be found. Reference(s): . Jun, 2020 - changed target install directory commitd64755ea5f. Sep, 2018 - #include migrated from procps.h commitfab37662efSigned-off-by: Jim Warner <james.warner@comcast.net>
