Commit 2f35c41f58 ("module: Replace module_ref with atomic_t refcnt")
changes the way refcnt is handled but did not update the gdb script to
use the new variable.
Since refcnt is not per-cpu anymore, we can directly read its value.

Analogously to the task list, convert the module list to a generator
function. It noticeably simplifies the code.

I tried to use these scripts in an ubuntu 14.04 host (gdb 7.7 compiled
against python 3.3) but there were several errors.
I believe this patch fixes these issues so that the commands now work (I
tested lx-symbols, lx-dmesg, lx-lsmod).
Main issues that needed to be resolved:
* In python 2 iterators have a "next()" method. In python 3 it is
__next__() instead (so let's just add both).
* In older python versions there was an implicit conversion
in object.__format__() (used when an object is in string.format())
where it was converting the object to str first and then
calling str's __format__(). This has now been removed so
we must explicitly convert to str the objects for which
we need to keep this behavior.
* In dmesg.py: in python 3 log_buf is now a "memoryview" object
which needs to be converted to a string in order to use string
methods like "splitlines()". Luckily memoryview exists in
python 2.7.6 as well, so we can convert log_buf to memoryview
and use the same code in both python 2 and python 3.
This version of the patch has now been tested with gdb 7.7 and both python
3.4 and python 2.7.6 (I think asking for at least python 2.7.6 is a
reasonable requirement instead of complicating the code with version
checks etc).

This adds a lsmod-like command to list all currently loaded modules of the
target.

Add the internal helper get_module_by_name to obtain the module structure
corresponding to the given name. Also export this service as a
convenience function.
