Subject: [PATCH] Fix 32-bit build

Bug #708824 "ghostscript 10.06.0 compilation failure on 32-bit archs"

nbytes shiouldn't be an intptr_t, it doesn't get used for pointer
arithmetic. Previously it was a uint, should be a int64_t, to fit with
all the other devices.

Checked other warnings, and found a (very minor) one in gdevdbit.c, fix
that while we're here (signed/unsigned mismatch, we don't really care).

Upstream-Status: Backport [https://github.com/ArtifexSoftware/ghostpdl/commit/3c0be6e4fcffa63e4a5a1b0aec057cebc4d2562f]
