Changeset 52403 in vbox for trunk/src/VBox/Runtime/tools/RTSignTool.cpp

Message:

SUP,IPRT: Extended RTLdrQueryPropEx with a pvBits parameter, RTLDRPROP_IMPORT_COUNT and RTLDRPROP_IMPORT_MODULE. Hook LdrLoadDll to validate DLLs before they get to NtCreateSection and the loader code/data can be messed up (windows 7 / 32-bit crash). Allow the kernel to buffer the log file, no real need that each write hits the disk.
