4d28fa78ab upstream: When system calls indicate an error they return -1, not
some arbitrary value < 0.  errno is only updated in this case.  Change all
(most?) callers of syscalls to follow this better, and let's see if this
strictness helps us in the future.

391ffc4b9d upstream: check in scp client that filenames sent during
remote->local directory copies satisfy the wildcard specified by the user.

This checking provides some protection against a malicious server
sending unexpected filenames, but it comes at a risk of rejecting wanted
files due to differences between client and server wildcard expansion rules.

For this reason, this also adds a new -T flag to disable the check.

42c5ec4b97 refactor libcrypto initialisation
Don't call OpenSSL_add_all_algorithms() unless OpenSSL actually
supports it.

Move all libcrypto initialisation to a single function, and call that
from seed_rng() that is called early in each tool's main().

dda78a03af Force Turkish locales back to C/POSIX; bz#2643
Turkish locales are unique in their handling of the letters 'i' and
'I' (yes, they are different letters) and OpenSSH isn't remotely
prepared to deal with that. For now, the best we can do is to force
OpenSSH to use the C/POSIX locale and try to preserve the UTF-8
encoding if possible.

0e059cdf5f upstream commit
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
