This merges the branch containing the revamped build system based around converting autogen from a bash script to a Perl program. Jeff has provided emails explaining the features contained in the change.
Please note that configure requirements on components HAVE CHANGED. For example. a configure.params file is no longer required in each component directory. See Jeff's emails for an explanation.

Valgrind header files if they weren't already in the compiler's
default header file search path. This commit fixes that typo and adds
a little more infrastructure (via an AC_SUBST) to pass in the relevant
CPPFLAGS to the build system for the valgrind memchecker component.
