When the test's child signals its parent and it exits the result of
getppid changes. On Ubuntu 20.04 this results in the ppid being that
of the GDM session, causing it to exit. Analysis and testing from pedro
at ambientworks.net
If we don't have LLONG_{MIN,MAX} but do have LONG_LONG_{MIN,MAX}
then use those instead. We do calculate these values in configure,
but it turns out that at least one compiler (old HP ANSI C) can't
parse "-9223372036854775808LL" without mangling it. (It can parse
"-9223372036854775807LL" which is presumably why its limits.h defines
LONG_LONG_MIN as the latter minus 1.)
Fixes rekey test when compiled with the aforementioned compiler.
On some platforms (at least older HP-UXes such as 11.11, possibly others)
setting SA_RESTART on signal handers will cause it to not interrupt
select(), at least for calls that do not specify a timeout. Try to
detect this and if found, don't use SA_RESTART.
POSIX says "If SA_RESTART has been set for the interrupting signal, it
is implementation-dependent whether select() restarts or returns with
[EINTR]" so this behaviour is within spec.
... unless we are actually going to use it. Fixes build on HP-UX
without the potential impact to other platforms of a header change
shortly before release.
If the system (or one of the dependencies) implements memmem but does
not define the header, we would not declare it either resulting in
compiler warnings. Check for declaration explicitly. bz#3102.
linking against the (previously external) USB HID middleware. The dlopen()
capability still exists for alternate middlewares, e.g. for Bluetooth, NFC
and test/debugging.

Including a function call in the test programs for the gcc stack
protector flag tests exercises more of the compiler and makes it more
likely it'll detect problems.
Enable -Wextra if compiler supports it
Set -Wno-error=format-truncation if available to prevent expected
string truncations in openbsd-compat from breaking -Werror builds
Rather than attempt to apply 14 years' worth of changes to OpenBSD's sha2
I imported the current versions directly then re-applied the portability
changes. This also allowed re-syncing digest-libc.c against upstream.
We shipped a BSD implementation of realpath() because sftp-server
depended on its behaviour.
OpenBSD is now moving to a more strictly POSIX-compliant realpath(2),
so sftp-server now unconditionally requires its own BSD-style realpath
implementation. As such, there is no need to carry another independant
implementation in openbsd-compat.

Previously configure would not select the "doc" man page format if
mandoc was present but nroff was not. This checks for mandoc first
and removes a now-superflous AC_PATH_PROG. Based on a patch from
vehk at vehk.de and feedback from schwarze at usta.de.
