Add MAXIMUM(), MINIMUM(), and ROUNDUP() to misc.h, then use those definitions rather than pulling <sys/param.h> and unknown namespace pollution. ok djm markus dtucker Upstream-ID: 712cafa816c9f012a61628b66b9fbd5687223fb8

To prevent screwing up terminal settings when printing to the terminal, for ASCII and UTF-8, escape bytes not forming characters and bytes forming non-printable characters with vis(3) VIS_OCTAL. For other character sets, abort printing of the current string in these cases. In particular, * let scp(1) respect the local user's LC_CTYPE locale(1); * sanitize data received from the remote host; * sanitize filenames, usernames, and similar data even locally; * take character display widths into account for the progressmeter. This is believed to be sufficient to keep the local terminal safe on OpenBSD, but bad things can still happen on other systems with state-dependent locales because many places in the code print unencoded ASCII characters into the output stream. Using feedback from djm@ and martijn@, various aspects discussed with many others. deraadt@ says it should go in now, i probably already hesitated too long Upstream-ID: e66afbc94ee396ddcaffd433b9a3b80f387647e0
