We need to add user-facing deprecation notices for TCP wrappers; start

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.

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.
