Request change name of function lookup_enum in libbabeltrace to make GDB use this lib

[Hui Zhu <teawater@gmail.com>]

Hi,

I am working on add CTF support to GDB.  You can see my patch review threads in:
http://sourceware.org/ml/gdb-patches/2012-11/msg00552.html
http://sourceware.org/ml/gdb-patches/2012-11/msg00554.html
http://sourceware.org/ml/gdb-patches/2012-11/msg00553.html
http://sourceware.org/ml/gdb-patches/2012-11/msg00555.html
http://sourceware.org/ml/gdb-patches/2012-11/msg00556.html

To make GDB support CTF read, I use libbabeltrace with GDB.  You can
see the patch in
http://sourceware.org/ml/gdb-patches/2012-11/msg00555.html.
I have a issue is  libbabeltrace have a function called lookup_enum
that is same with a GDB function.
I change the function name of GDB to handle this issue in my patch.

But Tom said let libbabeltrace to change function name is better.
So I send this mail to ask do you mind change the function name of
lookup_enum?   If you can change the function name that will be really
helpful for us.  Thanks a lot.
And I post a patch about change the function name in libbabeltrace.

Thanks,
Hui
