Some CFLAGS/LDFLAGS may disrupt the configure script's operation,
in particular santization and fuzzer options that break assumptions
about memory and file descriptor dispositions.
This adds two flags to configure --with-cflags-after and
--with-ldflags-after that allow specifying additional compiler and
linker options that are added to the resultant Makefiles but not
used in the configure run itself.
E.g.
env CC=clang-3.9 ./configure \
--with-cflags-after=-fsantize=address \
--with-ldflags-after="-g -fsanitize=address"
FreeBSD's <sys/capability.h> was renamed to <sys/capsicum.h> in 2014 to
avoid future conflicts with POSIX capabilities (the last release that
didn't have it was 9.3) so switch to that. Patch from des at des.no.
Include replacement timespeccmp() for systems that lack it.
Support time_t struct stat->st_mtime in addition to
timespec stat->st_mtim, as well as unsorted fallback.
Should fix bz#2603 - "Build with ldns and without kerberos support
fails if ldns compiled with kerberos support" by including correct
cflags/libs

Having _XOPEN_SOURCE unconditionally causes problems on some platforms
and configurations, notably Solaris 64-bit binaries. It was there for
the benefit of Linux put the required bits in the *-*linux* section.
Patch from yvoinov at gmail.com.
NetBSD added an strnvis and unfortunately made it incompatible with the
existing one in OpenBSD and Linux's libbsd (the former having existed
for over ten years). Despite this incompatibility being reported during
development (see http://gnats.netbsd.org/44977) they still shipped it.
Even more unfortunately FreeBSD and later MacOS picked up this incompatible
implementation. Try to detect this mess, and assume the only safe option
if we're cross compiling.
OpenBSD 2.9 (2001): strnvis(char *dst, const char *src, size_t dlen, int flag);
NetBSD 6.0 (2012): strnvis(char *dst, size_t dlen, const char *src, int flag);

Where possible, use Solaris setpflags to disable process tracing on
ssh-agent and sftp-server. bz#2584, based on a patch from huieying.lee
at oracle.com, ok djm.
Replace by defining IPPORT_RESERVED to zero on Cygwin, which should have
the same effect without causing problems syncing patches with OpenBSD.
Resync the two affected functions with OpenBSD. ok djm, sanity checked
by Corinna.
sshd was failing with:
ssh_sandbox_child: sandbox_init: dlopen(/usr/lib/libsandbox.1.dylib, 261):cw
image not found [preauth]
caused by chroot before sandboxing. Avoid by explicitly linking libsandbox
to sshd. Spotted by Darren.
Not all systems with Solaris privs have priv_basicset so factor that
out and provide backward compatibility code. Similarly, not all have
PRIV_NET_ACCESS so wrap that in #ifdef. Based on code from
alex at cooperi.net and djm@ with help from carson at taltos.org and
wieland at purdue.edu.
