Restructure the .gdbinit files:
.gdbinit.crash contains a top-level .gdbinit suitable for debugging
crash dumps
.gdbinit.serial contains a top-level .gdbinit suitable for serial
debugging
Each of these two files reads the following files:
.gdbinit.kernel: This file contains general macros suitable for kernel
debugging. It is not related to vinum
.gdbinit.vinum: This file contains macros specific to debugging
vinum.
.gdbinit.paths: Contains information about the location of the source
and object files on the system.
