Added new PeCoffGetEntryPoint lib function to get size of PE/COFF header. This is needed for debug prints with PE/COFF images that started as ELF or Mach-O. Moved and debugged ARM semihosting lib for RVD that prints out the debugger symbol load commands in a window on the debugger. Trying to write a script file, but that crashes RVD. Added debug print to BeagleBoard Sec that prints out RVD debugger command to load symbols for the Sec. Synced the rest of the code.
