This reverts commit e127a73d ("scripts/gdb: add a Radix Tree
Parser")

The python implementation of radix-tree was merged at the same time as
the radix-tree system was heavily reworked from commit e9256efc
("radix-tree: introduce radix_tree_empty") to 3bcadd6f ("radix-tree:
free up the bottom bit of exceptional entries for reuse") and no longer
functions, but also prevents other gdb scripts from loading.

This functionality has not yet hit a release, so simply remove it for
now

Python doesn't do automatic expansion of paths.  In case one passes path
of the from ~/foo/bar the gdb scripts won't automatically expand that
and as a result the symbols files won't be loaded.

Fix this by explicitly expanding all paths which begin with "~"

Change the read_u16 function so it accepts both 'str' and 'byte' as type
for the arguments.

When calling read_memory() from gdb API, depending on if it was built
with 2.7 or 3.X, the format used to return the data will differ ( 'str'
for 2.7, and 'byte' for 3.X ).

Add a function read_memoryview() to be able to get a 'memoryview' object

Linux makes use of the Radix Tree data structure to store pointers
indexed by integer values.  This structure is utilised across many
structures in the kernel including the IRQ descriptor tables, and
several filesystems.

This module provides a method to lookup values from a structure given
its head node.

Usage:

The function lx_radix_tree_lookup, must be given a symbol of type struct
radix_tree_root, and an index into that tree.

The object returned is a generic integer value, and must be cast
correctly to the type based on the storage in the data structure.

For example, to print the irq descriptor in the sparse irq_desc_tree at
index 18, try the following:

 (gdb) print (struct irq_desc)$lx_radix_tree_lookup(irq_desc_tree, 18)

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.
