Description of problem:
gdb.solib_address can't be used

Version-Release number of selected component (if applicable):
gdb-7.2-4.fc14.i686

How reproducible:
Always

Steps to Reproduce:
1. gdb
2. python
3. print dir(gdb)
4. end
5. q
  
Actual results:
$ gdb
(gdb) python
>print dir(gdb)
>end
[[...], 'selected_thread', 'solib_address (Long) -> String.\nReturn the name of the shared library holding a given address, or None.', 'string_to_argv', [...]]
(gdb) q

Expected results:
gdb
(gdb) python
>print dir(gdb)
>end
[[...], 'selected_thread', 'solib_address', 'string_to_argv', [...]]
(gdb) q

Additional info:
0) The entry for solib_address in GdbMethods[] is clearly incorrect.

That entry can be traced back to gdb-archer.patch:
$ grep -rInsE solib_address SOURCES/gdb*
SOURCES/gdb-archer.patch:8874:+                lib = gdb.solib_address (pc)
SOURCES/gdb-archer.patch:10373:+/* Implementation of gdb.solib_address (Long) -> String.
SOURCES/gdb-archer.patch:10377:+gdbpy_solib_address (PyObject *self, PyObject *args)
SOURCES/gdb-archer.patch:10665:+  { "solib_address (Long) -> String.\n\

1) Also note that gdbpy_solib_address() is now unused.

2) This could be trivial to patch. However, current gdb master uses gdb.solib_name() and gdbpy_solib_name() so it is not clear to me how to proceed here.
