Merge mediaclientaudio stub to latest baseline.

Add William's draft of mediaclientaudio stub.

stem_MediaClientAudio.dll - work in progress mmfclienttoneplayer first attempt is done, but not tested mmfclientautioplayer hasn't really started

Original source files from sf/os/mm/mmlibs/mmfw, to be reworked for stem_MediaClientAudio.dll

stem_MediaClientAudio.dll, work in progress

Original mmp and def files for MediaClientAudio.dll - from sf/os/mm/mmlibs/mmfw/MMPfiles/client

Mark econseik.dll as "In", to support eshell and other console-based test code

Add the evfp.dll extension on beagleboard, now that I've enabled floating point in that baseport.

Add missing EKData.dll to beagle_stem.oby, fix some lingering _syborg_ files in naviengine_stem.oby

Make trivial updates to two MMP files, to match the changes between PDK 3.0.2 and PDK 3.0.4 The updates are about case-consistency changes in LIBRARY names, but alas they don't agree on euser.lib (for example).

Add breakdeps\origins.txt to record the original location of modified files Add tools\check_for_mercurial_updates.pl which reads origins.txt and looks to see if the originals have changed in Mercurial

Clean up stem_rom.oby a little, add matching syborg_stem.oby, beagle_stem.oby, naviengine_stem.oby

Added tag PDK_3.0.4 for changeset 04364b20a2b8

Created TAGS branch

Rework java stubs as stem_* things, and updated rom_content.csv and static_dependencies.txt accordingly. Note that javadebugapi.dll is included, even though it was never referenced during startup.

Add original Java stub MMP files, to break ETEL dependency

Split syborg_stem_rom.oby into stem_rom.oby and syborg_stem.oby, and it still works.

Build the existing STUB versions of Java so it can safely be removed from the rom (and also reducing the dependency on etel)

Remove dependency of MCS on SAT, one step close to removing ETEL: boots but still gives and empty folder.

Add a version of the MCS SAT Handler ready for stemming

Update rom_content.csv and syborg_stem_rom.oby with the result of the "boot_ktrace_640" reduction

Revert to the last fully working syborg_stem_rom.oby (from change fc9981c83de7)

Update bulk_marking.pl to handle the optional cmds, which was the key to making the "boot_ktrace_640" reduction work correctly

Regenerate static_dependencies.txt from first principles, to original files as well as stem_* versions

Added more things in the syborg baseport which are vital to booting the ROM

Add cmncustomcmds.dll, which is required for the shutdown list - shutdown wasn't tested in the ktrace log

Add some more vital things to make a ROM boot

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
