[PATCH 0/3] limit number of cat and sed forks |

These three patches speed up libvirt's configure script by roughly 3%,
by avoiding repeated calls to sed (for AS_TR_SH and AS_TR_CPP, patches 1-2)
and cat (for _AC_DEFINE_UNQUOTED, patch 3). The AS_TR_SH and AS_TR_CPP
computations are moved to autoconf time. cat is replaced by printf.
Thanks,
Paolo

autoconf: prefer an unrolled loop for trivial AC_CHECK_FUNCS
autoconf: prefer an unrolled loop for trivial AC_CHECK_HEADERS
autoconf: refine quadrigraph test in _AC_DEFINE_UNQUOTED
