Subject: add some (void) casts for unused variables
X-Git-Tag: release-2.0.11-stable~14
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=65707d7c3cd71e11ed58c18f5840847e44f5ec69;p=libevent

add some (void) casts for unused variables

All these places already have an XXX marker, so we know we need to fix
them later. Let's not clutter the static analysis results with them.
