Info-list operations should use 'list' as the parameter rather than 'ptr' #502
Description
Overview
While working on #492 (comment)
we found that the name ptr for the list parameter in the PMIx_Info_list_get_info was unclear. However after review we found that this ptr problem is pervasive and should be tackled all at once.
Motivation
Clarification of parameter intent is always good.
Discussion
Mirror change should be made to Open PMIx and the ABI document.
