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

Add a function to enable security-related malloc_options.
With and ok deraadt@, something similar has been in the snaps for a while.

Don't attempt to append a nul quote char to the filename. Should prevent
fatal'ing with "el_insertstr failed" when there's a single quote char
somewhere in the string. bz#2238, ok markus@
[PROTOCOL sftp-client.c sftp-client.h sftp-server.c sftp.1 sftp.c]
fsync@openssh.com protocol extension for sftp-server
client support to allow calling fsync() faster successful transfer

[sftp-client.c sftp-client.h sftp.c]
add a "-l" flag for the rename command to force it to use the silly
standard SSH_FXP_RENAME command instead of the POSIX-rename- like
posix-rename@openssh.com extension.
intended for use in regress tests, so no documentation.
[sftp-client.c sftp-client.h sftp.1 sftp.c]
sftp support for resuming partial downloads; patch mostly by Loganaden
Velvindron/AfriNIC with some tweaks by me; feedback and ok dtucker@
[sftp.c]
Make sftp's libedit interface marginally multibyte aware by building up
the quoted string by character instead of by byte. Prevents failures
when linked against a libedit built with wide character support (bz#1990).
"looks ok" djm
[sftp.c]
fix NULL deref when built without libedit and control characters
entered as command; debugging and patch from Iain Morgan an
Loganaden Velvindron in bz#1956
[sftp.c]
Don't leak list in complete_cmd_parse if there are no commands found.
Discovered when I was ``borrowing'' this code for something else.
ok djm@
[sftp-server.c sftp.1 sftp-client.h sftp.c PROTOCOL sftp-client.c]
add a protocol extension to support a hard link operation. It is
available through the "ln" command in the client. The old "ln"
behaviour of creating a symlink is available using its "-s" option
or through the preexisting "symlink" command; based on a patch from
miklos AT szeredi.hu in bz#1555; ok markus@
[sftp.c configure.ac openbsd-compat/glob.c openbsd-compat/glob.h]
make use of new glob(3) GLOB_KEEPSTAT extension to save extra server
rountrips to fetch per-file stat(2) information.
NB. update openbsd-compat/ glob(3) implementation from OpenBSD libc to
match.
