[RFA 0/3] Make global symbol objfile search order arch-dependent

[Joel Brobecker <brobecker at adacore dot com>]

Hello,

Re: http://www.sourceware.org/ml/gdb-patches/2012-05/msg01026.html

This patch re-implement objfile searching order to make it gdbarch-
dependent.  There are three patches to this series:

  #1: Reverts my first patch, in order to start from a clean slate.
  #2: Introduces the new gdbarch method, and modifies the relevant
      code to use it, instead of using ALL_OBJFILES.  The gdbarch's
      default implemention, which is equivalent to ALL_OBJFILES,
      is still used for all platforms, so there should be no functional
      change on any platform, yet.
  #3: Introduces a windows-specific version of that new gdbarch
      method, and installs it for x86 and amd64 windows targets.

The patch series has been tested on x86_64-linux, as well as on
x86-windows, but using AdaCore's testsuite.  No regression observed.
