Subject: state, map: constify references to xkb_key
X-Git-Tag: xkbcommon-0.2.0~146
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c2570d51d1061146c6165b757af5125bb96b59d8;p=platform%2Fupstream%2Flibxkbcommon.git

state, map: constify references to xkb_key

Makes it clear that we treat the keys as immutible values in these
files.
