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 "~"

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)

A few instances of "fimware" instead of "firmware" were found.  Fix
these and add it to the spelling.txt file.

scripts/decode_stacktrace.sh presently displays module symbols as

	func+0x0ff/0x5153 [module]

Add a third argument: the pathname of a directory where the script
should look for the file module.ko so that the output appears as

	func (foo/bar.c:123) module

Without the argument or if the module file isn't found the script prints
such symbols as is without decoding.

By default, "seq" counts from 1, but processes were starting counting
from 0, so when interrupted, coccicheck would leave the 0th process
running.

After commit 21a59991 ("scripts/package/Makefile: rpmbuild is needed
for rpm targets"), it is no longer possible to specify RPMOPTS.
For example, we can no longer able to control _topdir using the following
make command.
make RPMOPTS="--define '_topdir /home/xyz/workspace/'" binrpm-pkg

Fixes: 21a59991 ("scripts/package/Makefile: rpmbuild is needed for rpm targets")
