[PATCH] Allow user-defined as a category for python gdb macros (resend)

Hi.
The VMware legal folks and FSF legal folks seem to be done with their
back and forth, and I am told it is now legally ok for this patch to be
committed.
This patch allows python macros to coexist with legacy gdb macros in
user-defined category. This way, it's possible to organize your macros
such that `help user` shows both legacy and python macros. I also
modified the documentation to use the `user` category in the example
python macro. It seemed like a more reasonable default category than
`obscure`.
2012-02-13 Scott J. Goldman <scottjg@vmware.com>
* gdb.texinfo: put example python macro in COMMAND_USER category
rather than COMMAND_OBSCURE.
* py-cmd.c (cmdpy_init): treat class_user as a valid class in error check
(gdbpy_initialize_commands): Add COMMAND_USER as a constant in
gdb python api.
* top.c (execute_command): only execute a user-defined command as a
legacy macro if c->user_commands is set.
