Implemented a new value type for the internal <sqldata/> XML format, which will
store data in an PostgreSQL array.  This is used now to store the CPU core spread
of the socket in a sepearate field in rtevalruns_details.

Have not yet implemented extraction new cpu_topology tags, but
the summary of this information will go into the num_cpu_cores and
num_cpu_sockets fields in the database.  Right now it only takes
the /rteval/hardware/cpu_cores and puts it into num_cpu_cores

- This database schema introduces the rteval_info table which should contain
  rather static information about the current rteval installation.

- New data fields from cyclictest are introduces (variance and mean_abs_dev)

- Added //sqldata/@schemaver attributes to all defined tables in xmlparser.xsl

- Introduced a delta-1.0_1.1.sql file which will update the old 1.0 based
  database schema to the new 1.1 version.

- Rewrote the complete autotools setup for rteval server to also include the XMLRPC
  interface
- Compiles and installs both the Python files needed for Apache+mod_python and the
  files needed for the rteval_parserd
- ./configure accepts --with-xmlrpc-webroot to set the directory of the XML-RPC
  files needed for mod_python.  If this is not set, those files will not be installed.
- Moved the sql/rteval-1.0.sql file into the server directory, where it is needed
  and install this file into the doc directory
