libvirt/autobuild.sh
Daniel P. Berrange 851117bd7a Enable all warnings permanently & default to -Werror for GIT builds
Given that we auto-detect whether each -Wxxxx flag is supported by
GCC, and we are warning-free and use automake silent rules, there
is no compelling reason to allow compile warnings to be disabled.

Replace the --enable-compile-warnings flag with a simpler
--enable-werror flag, which defaults to 'yes' if building
from GIT, or 'no' if building from tar.gz

This helps ensure that everyone writing patches for libvirt will
take care to fix their warning problems before submitting for
review

* autobuild.sh: Force -Werror
* configure.ac: Update for LIBVIRT_COMPILE_WARNINGS macro change
* m4/virt-compile-warnings.m4: Permanently enable all warnings,
  auto-enable Werror for GIT builds
