MFH: - Changed AC_ARG_* options to PHP_ARG_* options.

MFH: - Some cleanups here and there
MFH: - Enabled PHP_CHECK_CONFIGURE_OPTIONS (checks for unknown configure
MFH:   options)
# Note to Marcus: ext/dba/config.m4 needs to be "converted" to use
# the PHP_ARG_* options. I did't touch it needs quite a lot of work to keep
# it's current behaviour regarding "enabled-by-default" parts of it.
#
# Hint: By using the PHP_ARG_* options you have the "default" option.. ;)
