[xslt] [PATCH] Modernize configure script

[Thierry Reding <thierry reding avionic-design de>]

When running configure.in through recent versions of autoconf, they will
complain about usage that won't be supported in future versions. This
commit uses the AC_INIT() macro in the recommended syntax that receives
the package name and version as parameters and both can be dropped from
the AM_INIT_AUTOMAKE invocation. The latter is passed the foreign option
instead to mark it as a non-GNU project.

Another recommendation for modern autotools is to put m4 macros in a
separate directory, so this commit creates the m4 directory in the
autogen.sh script and instructs the autotools to look there for m4
files.
