[PATCH 0/7 V2] Import the rename gnulib module

[Yao Qi <yao at codesourcery dot com>]

This patch series is to import rename gnulib module and other
dependent modules.  We need rename module to fix some
fileio.exp fails on mingw32 host, on which the errno setting
isn't compliance with POSIX.  V1 can be found
https://sourceware.org/ml/gdb-patches/2014-10/msg00837.html

rename module depends on readlink, lstat and canonicalize-lgpl modules,
and they are used by GDB too, so this patch series imports them
explicitly and use them.  Patches 1, 3, and 5 import readlink,
lstat and canonicalize-lgpl respectively.  Patches 2, 4, and 6
are to use these api unconditionally.  Patch 7 is about importing
rename module.

Regression tested on x86_64-linux and arm-eabi both on linux host
ahd mingw32 host.  Two fails in fileio.exp on mingw32 host are
fixed.
