Bochs/bochs/gui/gui.cc
Volker Ruppert b142dbcc2c - add new function hdimage_open_file() that returns file size and modification 
time if requested (reduces code duplication)
- 'vpc' image mode: moved header check to a separate function that opens the
  file, checks header/footer and returns disk type (if requested)
- implemented restore function for 'vpc' mode images
- gui: updated yes/no dialog message after saving state
- save/restore documentation update (TODO: developer doc)
