Some binaries may be compiled with a different page offset. Add
an option to allow the page offset to be adjusted properly.

Commit 4eb3aa20
(linux-ramdump-parser-v2: Update RTB for 64-bit) added support for
64-bit RTB parsing but broke backwards compatibility for old branches
that don't have the 64-bit changes. Update the parser to support
both old and new formats.

Some parsers may need to use the out file for their output. Currently,
when writing to stdout, we have 'None' as a parser which blows up
with dmesg parsing:

Traceback (most recent call last):
File "ramparse.py", line 318, in <module>
    p.cls(dump).parse()
File "dmesg.py", line 20, in parse
    dmesglib.DmesgLib(self.ramdump, print_out.out_file).extract_dmesg()
File "dmesglib.py", line 79, in extract_dmesg
    self.extract_dmesg_binary()
File "dmesglib.py", line 72, in extract_dmesg_binary
    self.outfile.write(f)
AttributeError: 'NoneType' object has no attribute 'write'

Make a default file of sys.stdout to do something reasonable when writing
to stdout. --stdout is mostly a debugging feature.

The arm32 version of stack unwinding was missing a function. Add it
back.

If a zillion billion differences are found in the RO area, just print to
the log once to notify the operator of that fact, instead of printing a
zillion billion times.

Sometimes it's useful to force a flush of the global outfile. Provide a
method to do so and use it in the main parser loop.

It can be useful to know which parser is currently running and
how long each parser takes to run. Add some progress status
reporting to this end.

msm_rtb_state.step_size should be either 1 or num_cpus(). If it's
greater than num_cpus() error out.

Currently the registered parsers can be run in basically any order. It
would be slightly messy to run them in the order the user specified on
the command line, so just run them alphabetically for now.

This is needed to do regression testing on the LRDP (diff'ing output of
the same dumps with different LRDP code).

To generate proper simulator launching scripts, the TTBR needs
to be set in the MMU object. This was missing for LPAE page tables.
Set it.

For reasons ranging from mangled dumps to bugs in code, the parser may
generate exceptions while parsing. Rather than terminate the entire
script, handle exceptions in a more graceful fashion.

If the user has python2.7 installed but it's not the default interpreter
on their system, they might get confused when they invoke the parser and
get a message about needing to install 2.7 even though they already have
it installed. Add some instructional messages about this situation to
the 2.6 invocation warning message as well as the README.

Add support to the ramdump parser to parse debug image v2

dumps.

We don't support python3 at all and python2.6 can only be used if the
user installs an extra package (OrderedDict [1]). Ask for python2
explicitly in the shebang line to resolve the python3 issues and print
some instructions to the user regarding python2.6 when that is used.

If the user insists on using python2.6, provide a command line
switch (--force-26) to skip the version check. To reduce clutter, don't
document this switch in the --help text but inform the user about its
existence when we error out due to the python2.6 check.

In order to even print an error message in python3 we have to first
ensure that our code is valid in python3, otherwise the interpreter
fails to even start executing our code (so we can't print any
messages). Use 2to3 to patch up some print statements, etc. Also fix
inconsistent whitespace, which is a syntax error on python3.

ListWalker.__init__ was recently changed to remove some unneeded
arguments. The vmalloc parser was also updated at roughly the same time
with a new usage of the ListWalker class and was using the old
constructor. Update it.

It's not always useful to pass extra data to the list walker function.
For example, if the list walker function is a class method, state can be
passed around by simply modifying class instance variables. Update
`ListWalker.walk' to accept extra arguments optionally, not require
them.
