Changelog:

 - Updated the embedded gdb version to FSF gdb-7.3.1.  This change is
   required for kernels built with gcc-4.6.1, which now defaults to
   using -gdwarf-4.  When using prior versions of crash on such a
   vmlinux file, it fails immediately with the message "Dwarf Error:
   wrong version in compilation unit header (is 4, should be 2) [in
   module vmlinux]" followed by "crash: vmlinux: no debugging data
   available".

 - Incremental patch for the SADUMP dumpfile support that was introduced
   in crash-5.1.8.  The patchset fixes minor bugs, cleans up the sadump 
   module, addresses the issue of gathering the first 640KB backup from 
   a kdump-enabled kernel, prepares for makedumpfile's support of the 
   SADUMP format, and has "bt" display the stored register set when the
   compressed kdump was generated from an SADUMP dumpfile.

 - Fix for the "gdb" command, or any command that resolves to a gdb
   command, to allow redirection to a pipe or file.  This addresses a
   regression that was introduced by an unrelated "gdb" command fix 
   in crash-5.1.4 that prevented the stripping of quotation marks from 
   the input line.  Without the patch, redirection of a "gdb" command
   to a pipe or file fails with the error message "gdb: gdb request
   failed: <original-command-line-including-redirection>".

 - Fix for live system analysis of 32-bit PPC kernels.  Without the
   patch, the session would fail after displaying the error message:
     WARNING: machine type mismatch:
     crash utility: PPC
     vmlinux: (unknown)

 - Fix to allow vmalloc memory access on 32-bit PPC kernels.  Without
   the patch, the warning message "WARNING: cannot access vmalloc'd 
   module memory" would be displayed during invocation, and kernel
   virtual memory that was vmalloc'd could not be accessed.

 - Fix to correctly gather task addresses from 32-bit PPC kernels.  
   Without the patch, during invocation a stream of error messages 
   indicating "crash: invalid task address in pid_hash: <address>"
   would be displayed.

 - Fix for the "bt" command in 32-bit PPC kernels.  Without the patch,
   the "bt" command would generate a segmentation violation.
