[PATCH xserver 0/4] A few meson fixes

[Peter Harris]

Mostly I was annoyed at the unused return value warning from the
non-arc4random path. I noticed a few other minor things while I was in
there.

Peter Harris (4):
      meson: Detect arc4random_buf
      meson: Detect more functions
      meson: Only detect each function once
      meson: Detect strlcat/strlcpy/reallocarray in libbsd
