Hello,

This is related to: 
http://sourceware.org/ml/gdb-patches/2013-01/msg00748.html. Changes from 
this patch are needed to finish off the work started in that thread.

As per Jan's request, this patch adds 'build-id' to the gdbserver 
response. The value is hex encoded string representing 
.note.gnu.build-id section of the corresponding shared library.

Majority of the patch is refactoring to reuse code. The real change is 
in gdbserver/linux-low.c.

Thanks,
