  1. Add function to get memory context stats for processes 

    This adds a function for retrieving memory context statistics
and information from backends as well as auxiliary processes.

When calling the function it sends a signal to the specified
process to submit statistics regarding its memory contexts
into dynamic shared memory.  Each memory context is returned
in detail, followed by a cumulative total in case the number
of contexts exceed the max allocated amount of shared memory.
Each process is limited to use at most 1Mb memory for this.

A summary can also be explicitly requested by the user, this
will return the TopMemoryContext and a cumulative total of
all lower contexts.

In order to not block on busy processes the caller specifies
the number of seconds during which to retry before timing out.
In the case where no statistics are published within the set
timeout,  the last known statistics are returned, or NULL if
no previously published statistics exist.  This allows dash-
board type usages to continually publish data even if the
target process is temporarily congested.  Context records
contain a timestamp to indicate when they were submitted.
