Improve crypto ordering for Encrypt-then-MAC (EtM) mode
MAC algorithms.
Previously we were computing the MAC, decrypting the packet and then
checking the MAC. This gave rise to the possibility of creating a
side-channel oracle in the decryption step, though no such oracle has
been identified.
This adds a mac_check() function that computes and checks the MAC in
one pass, and uses it to advance MAC checking for EtM algorithms to
before payload decryption.

Explicitly check for 100% completion to avoid potential
floating point rounding error, which could cause progressmeter to report 99%
on completion. While there invert the test so the 100% case is clearer. with

There are a small number of "upstream" commits that do not correspond to
a file in -portable. This file tracks those so that we can reconcile
OpenBSD and Portable to ensure that no commits are accidentally missed.
If you add something to .skipped-commit-ids please also add an upstream
ID line in the following format when you commit it.

Back out rev 1.28 "Check min and max sizes sent by the
client" change. It caused "key_verify failed for server_host_key" in clients
that send a DH-GEX min value less that DH_GRP_MIN, eg old OpenSSH and PuTTY.

Where possible, use Solaris setpflags to disable process tracing on

at oracle.com, ok djm.
Fix two rare edge cases: 1. If vasprintf() returns < 0,
do not access a NULL pointer in snmprintf(), and do not free() the pointer
returned from vasprintf() because on some systems other than OpenBSD, it
might be a bogus pointer. 2. If vasprintf() returns == 0, return 0 and ""
rather than -1 and NULL.
Besides, free(dst) is pointless after failure (not a bug).

Backout rev. 1.43 for now.
The function update_progress_meter() calls refresh_progress_meter()
which calls snmprintf() which calls malloc(); but update_progress_meter()
acts as the SIGALRM signal handler.

Even when only writing an unescaped character, the dst
buffer may need to grow, or it would be overrun; issue found by tb@ with
malloc.conf(5) 'C'.
While here, reserve an additional byte for the terminating NUL
up front such that we don't have to realloc() later just for that.

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
