Handle -displayfd and an explicit display number sensibly
commit bc348bd2c42f3f18786085ccef2f010eff5bf3d2
Author: Jon TURNEY <jon.turney@dronecode.org.uk>

Handle -displayfd and an explicit display number sensibly
Handle -displayfd and an explicit display number sensibly, e.g. use the
explicitly specified display number, and write it to the displayfd
v2: displayfd might be 0, so use -1 as invalid value
v3: Rebase for addition of NoListenAll flag
