REVIEW: https://review.gluster.org/21070 (protocol: don't use alloca) posted
(#1) for review on master by Amar Tumballi

COMMIT: https://review.gluster.org/21070 committed in master by "Amar Tumballi"
<amarts at redhat.com> with a commit message- protocol: don't use alloca

current implementation of alloca can cause issues when strings larger
than the allocated buffer is passed to the xdr. Hence it makes sense
to allow XDR decode functions to deal with memory allocations, which
we can free later.

Fixes: bz#1625097
