Andrew Tridgell e8d10dc2ad old_versions: commit static binaries of old rsync releases ...

Nine statically-linked, stripped binaries for the version-mixing test
suite (and ad-hoc cross-version behaviour checks): every x.y.0 release
from 2.6.0 (2004, protocol 27) through 3.4.0, plus the 3.1.3/3.2.7/3.4.1
point releases. 2.6.0 is the practical floor; older tags need more
porting to build on a current toolchain.

build_static.sh rebuilds any release from its git tag, applying the
minimal patches needed to compile old sources on a modern toolchain:
K&R lseek64 redecl, gettimeofday, -std=gnu11, --disable-openssl, and
_FORTIFY_SOURCE disabled (modern FORTIFY=3 turns latent benign over-reads
in old rsync into aborts when it runs as a server). Pre-3.0 trees ship
configure.in, so it regenerates configure (autoheader/autoconf) after
neutralizing the dead AC_LIBOBJ replacement fallbacks, generates proto.h,
and stubs the dropped vendored lib/addrinfo.h -- all guarded to no-op on
newer versions.

.gitattributes marks the binaries binary (so the text=auto rule can't
corrupt them) and export-ignore (kept out of the release tarball).
