Some SSH servers eg "ConfD" drop the connection if the client sends the
new IUTF8 (RFC8160) terminal mode even if it's not set. Add a bug bit
for such servers and avoid sending IUTF8 to them. ok djm@

These seem to have been missed during the replacement of mysignal
with #define signal in commit 5ade9ab. Both include the requisite
headers to pick up the #define.
The code required to support it is quite invasive to the mainline
code that is synced with upstream and is an ongoing maintenance burden.
Both the hardware and software are literal museum pieces these days and
we could not find anyone still running OpenSSH on one.
The signal handlers from the original ssh1 code on which OpenSSH
is based assume unreliable signals and reinstall their handlers.
Since OpenBSD (and pretty much every current system) has reliable
signals this is not needed. In the unlikely even that -portable
is still being used on such systems we will deal with it in the
compat layer. ok deraadt@

This adds checks for gcc and clang flags for mitigations for Spectre
variant 2, ie "retpoline". It'll automatically enabled if the compiler
supports it as part of toolchain hardening flag. ok djm@
