Introduce prefixes "etel", "mm" and "perf" for the etel removal, the devsound removal and the hardware floating point performance optimisations

Add --options argument to pass in the (comma separated lists of) prefixes for optional "What" commands For example, the use of vfp version of OpenVG could be indicated by "vfp_Stem", in which case the alteration will only be made if "--options vfp" is included on the filter_obyfile.pl command line.

Update filter_obyfile.pl to report the "minimal ROM" executables Update bulk_marking.pl to handle lists of exes both with and without the -x option Update summarise_kerneltrace.pl to deal with the interspersed "DTimer::Create" information, and update summary.txt

Add NOEXPORTLIBRARY, + minor tweaks

Add ktrace.oby, as an easy way to add the KPROC+KTHREAD+KDLL tracing - use buildrom -D_DEBUG -fm=featuredatabase.xml syborg_stem_rom.oby ktrace.oby which will override the standard kerneltrace

Use DEBUG_DIR\euser.dll to assist a wider range of debugging, and remove spurious extra kerneltrace statement

Update utility for processing kerneltrace output, and add "analysis" directory containing a boot trace and the summary The "boot" activity included running weatherinfo and deform, so it should have touched all of the executables we really need

Utility to remove the problematic section of rombuild.log, so that elf4rom can work properly

Reinstate startup/customcmds.mmp etc, which fell off by accident
