This provides a single entry point to access some information about the state of MultiXacts, able to return some data about multixacts offsets and counts. Originally this function was only able to return some information about the number of multixacts and multixact members, extended here to provide some data about the oldest multixact ID in use and the oldest offset, if known. This change has been proposed in a patch that aims at providing more monitoring capabilities for multixacts, and it is useful on its own. GetMultiXactInfo() is added to multixact.h, becoming available for out-of-core code. Extracted from a larger patch by the same author.
