e87228c600 Replace literal uses of /usr/local in C sources with _PATH_LOCALBASE
Literal references to /usr/local exist in a large number of files in
the FreeBSD base system. Many are in contributed software, in configuration
files, or in the documentation, but 19 uses have been identified in C
source files or headers outside the contrib and sys/contrib directories.

This commit makes it possible to set _PATH_LOCALBASE in paths.h to use
a different prefix for locally installed software.

In order to avoid changes to openssh source files, LOCALBASE is passed to
the build via Makefiles under src/secure. While _PATH_LOCALBASE could have
been used here, there is precedent in the construction of the path used to
a xauth program which depends on the LOCALBASE value passed on the compiler
command line to select a non-default directory.

This could be changed in a later commit to make the openssh build
consistently use _PATH_LOCALBASE. It is considered out-of-scope for this
commit.

34a2f67d19 ssh: Remove AES-CBC ciphers from default server and client lists
A base system OpenSSH update in 2016 or so removed a number of ciphers
from the default lists offered by the server/client, due to known
weaknesses.  This caused POLA issues for some users and prompted
PR207679; the ciphers were restored to the default lists in r296634.

When upstream removed these ciphers from the default server list, they
moved them to the client-only default list.  They were subsequently
removed from the client default, in OpenSSH 7.9p1.

The change has persisted long enough.  Remove these extra ciphers from
both the server and client default lists, in advance of FreeBSD 13.

4691b632e8 Don't log normal login_getpwclass(3) result.
The logging was introduced in r314527 but doesn't appear to be useful
for regular operation, and as the result, for users with no class set
(very common) the administrator would see a message like this in their
auth.log:

  sshd[44251]: user root login class [preauth]

(note that the class was "" because that's what's typically configured
for most users; we would get 'default' if lc->lc_class is chosen)

Remove this log as it can be annoying as the lookup happen before
authentication and repeats, and our code is not acting upon lc_class
or pw_class directly anyways.

This is currently staged in vendor/ as part of the 8.0p1 import, which isn't
quite ready to land. Given that this is a simple one-line fix, apply it now
as the fallout will be pretty minimal.

-fno-common will become the default in GCC10/LLVM11.

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.

55cc6970c9 scp: validate filenames provided by server against wildcard in client
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.
