- (djm) [configure.ac] include leading zero characters in OpenSSL version
   number; fixes test for unsupported versions
 - (djm) [sshbuf-getput-crypto.c] Fix compilation when OpenSSL lacks ECC
 - (djm) [openbsd-compat/bsd-snprintf.c] Fix compilation failure (prototype/
   definition mismatch) and warning for broken/missing snprintf case.
 - (djm) [configure.ac] double braces to appease autoconf
 - (djm) [sshd.c] Ignore SIGXFSZ in preauth monitor child; can explode on
   lastlog writing on platforms with high UIDs; bz#2263
 - (djm) [configure.ac] We now require a working vsnprintf everywhere (not
   just for systems that lack asprintf); check for it always and extend
   test to catch more brokenness. Fixes builds on Solaris <= 9
 - (djm) [sftp-server.c] Some systems (e.g. Irix) have prctl() but not
   PR_SET_DUMPABLE, so adjust ifdef; reported by Tom Christensen
 - (djm) [bufec.c] Skip this file on !ECC OpenSSL
 - (djm) [INSTALL] Recommend libcrypto be built -fPIC, mention LibreSSL,
   update OpenSSL version requirement.
