In r339216 a privsep wrapper was added for login_getpwclass to address
PR 231172. Unfortunately the change used the MON_AUTH flag in the
wrapper, and MON_AUTH includes MON_AUTHDECIDE which triggers an
auth_log() on each invocation. getpwclass() does not participate in the
authentication decision, so should be MON_ISAUTH instead.

upstream: when checking that filenames sent by the server side

OpenSSH-portable commits:
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.

This completely removes client-side support for the SSH 1 protocol,
which was already disabled in 12 but is still enabled in 11. For that
reason, we will not be able to merge 7.6p1 or newer back to 11.
Adjust notification points slightly to catch all auth failures,
rather than just the ones caused by bad usernames.
Modify notification point for bad usernames to send new type of
BLACKLIST_BAD_USER. (Support in libblacklist will be forthcoming soon.)
Add guards to allow library headers to expose the enum of action values.

Change the calls to of blacklist_init() and blacklist_notify to be
macros defined in the blacklist_client.h file. This avoids
the need for #ifdef USE_BLACKLIST / #endif except in the
blacklist.c file.
Remove redundent initialization attempts from within
blacklist_notify - everything always goes through
blacklistd_init().
Added UseBlacklist option to sshd, which defaults to off.
To enable the functionality, use '-o UseBlacklist=yes' on
the command line, or uncomment in the sshd_config file.
