Start of autoconfiscation.

Not finished yet, still need to do the trusted/validator*
directories, as well as the final link.

Also need to factor out common CPPFLAGS, CFLAGS, etc, and
AC_SUBST directory specific flags.
Finish building the .so library

Still need to double-check all the CPPFLAGS and CFLAGS.  Also need to
drop a dev header for -dev packages
Build valz and valzo
Make validator nodist

We only need this for internal sanity checks, so I have stopped
installing it in /bin
set subdir-objects on all .am files
Add subdir-objects to test dir
force a m4 directory
update extra_dists
Bootstrap script for generating a configure script

This simply checks for the presence of automake, autoconf and libtool
before calling autoreconf. That way we can provide better error
messages.
add real author names
make boostrap more autogenny
honor the chromium native_client license
