      kdd.c: Add support for initial handshake in KD protocol for Win 7, 8 and 
10 (64 bit)
      
      Current implementation of find_os is based on the hard-coded values for
      different Windows version. It uses the value for get the address to
      start looking for DOS header in the given specified range. However, this
      is not scalable to all version of Windows as it will require us to keep
      adding new entries and also due to KASLR, chances of not hitting the PE
      header is significant. We implement a way for 64-bit systems to use IDT
      entry to get a valid exception/interrupt handler and then move back into
      the memory to find the valid DOS header. Since IDT entries are protected
      by PatchGuard, we think our assumption that IDT entries will not be
      corrupted is valid for our purpose. Once we have the image base, we
      search for the DBGKD_GET_VERSION64 structure type in .data section to
      get information required for handshake.
      
      Currently, this is a work in progress feature and current patch only
      supports the handshake and memory read/write on 64-bit systems.
      
      NOTE: This is the Updated version of the previous patch submitted

      kdd.c: Add support for initial handshake in KD protocol for Win 7, 8 and 
10 (64 bit)
      
      Current implementation of find_os is based on the hard-coded values for
      different Windows version. It uses the value for get the address to
      start looking for DOS header in the given specified range. However, this
      is not scalable to all version of Windows as it will require us to keep
      adding new entries and also due to KASLR, chances of not hitting the PE
      header is significant. We implement a way for 64-bit systems to use IDT
      entry to get a valid exception/interrupt handler and then move back into
      the memory to find the valid DOS header. Since IDT entries are protected
      by PatchGuard, we think our assumption that IDT entries will not be
      corrupted is valid for our purpose. Once we have the image base, we
      search for the DBGKD_GET_VERSION64 structure type in .data section to
      get information required for handshake.
      
      Currently, this is a work in progress feature and current patch only
      supports the handshake and memory read/write on 64-bit systems.
      
      NOTE: This is the Updated version of the previous patch submitted
