[RFC] Add handling of VK_HOME, VK_END, VK_DELETE and VK_INSERT for mingw hosts

[Pierre Muller]

  The patch below adds support 
for Home, End, Insert and Delete keys for mingw hosts.
  It works both for mingw32 and mingw64 native builds.

  I also added some description of the bounds added.

  The code that handles console input in gdb/ser-mingw.c
has the 8 keys handled after my patch plus 
VK_PRIOR and VK_NEXT, which correspond to PageUp and PageDown keys...
Any ideas what readline translation would be useful for those?


  What repository is the main readline maintainer?
Should I submit the patch there?
