[patch gdb]: Fix some DOS-path related issues in gdb

[Kai Tietz <ktietz70 at googlemail dot com>]

Hello,

This patch fixes some issues related to DOS file-system filenames and
paths. I am not sure, if I
hit all places, nevertheless I am sure I hit most.
This patch uses the libiberty functions & macros about
directory-separator checks, absolute-path checks,
and the filename-comparision functions.
