pledge(2) all programs
All programs except mshow have a very tight set of promises. mshow has a broad set of promises and might be a good future candidate to further restrict using unveil(2). This patch is based on commit 0300a112 by Alex Holst (dated 2017-12-07), which was proposed in GH PR #79. * pledged mpick, mflow and mdate so that now all programs are pledged * removed some unneeded promises and added some missing promises * move err.h include and OpenBSD ifdef into a new xpledge.h * cleaned up code aligning and whitespace Closes: #179 [via git-merge-pr]
