"Pin", rather than "keep", dynamic shared memory mappings and segments.

Browse Source 
Nobody seemed concerned about this naming when it originally went in,
but there's a pending patch that implements the opposite of
dsm_keep_mapping, and the term "unkeep" was judged unpalatable.
"unpin" has existing precedent in the PostgreSQL code base, and the
English language, so use this terminology instead.

Per discussion, back-patch to 9.4.
