Kaslr enabled dump has to pass adjusted address into GDB to get correct
symbol information. because vmlinux is loaded witihout kaslr offset.

This patch fixes the need for a hard coded value
to specify upper limit on length of the Linux Banner.

get_version() inside ramdump.py has been renamed to
get_matched_version() to reflect the true nature of
the function.

Added a variable banner_len in get_matched_version()
which is the length of linux_banner returned by
gdbmi.get_value_of_string('linux_banner').
This variable is further passed to read_cstring()
function to specify the max limit of characters to
be read. We are dynamically calculating the length
using gdb to read linux banner.

gdb returns 200 chars by default on symbol read. if linux_banner is more than 200 chars, we are seeing symbol mismatch

	 linux_banner string O/P was coming in different format,
	 so we have added proper regular expression to match it

	Read the linux banner data from vmlinux rodata section.
	Also read the linux banner data from ramump. Do a matching of both the data.
	If success then ramparser will go ahead and proces further

Current Linux Ram Dump Paser scripts are only able to load kernel
symbols by default. No loadable modules' symbols will be parsed
at startup time, which may result in 'unknown symbols' in some
cases, especially when checking SLAB info on dual-wifi platforms.

With this change, loadable modules' symbols can be parsed on
script startup by the following configurations:

1) Put all symbols under a certain dir, such as:

<dump_location>/symbols/wlan.ko
<dump_location>/symbols/wlan_sdio.ko

2) Add --sym_path when invoking the scripts, such as:

python %RAM_DUMP_PARSER_PATH%\ramparse.py --sym_path
<dump_location>/symbols

With the above actions, all loadable modules' symbols will be
parsed and stored for subsequent information dumping. Symbol
loading commands will also be added into the Trace32 startup
script.

Add '--kaslr-offset' option.  This specifies the offset for loading symbols
for a KASLR-enabled kernel.

Some of our module documentation is a bit lacking.  Fix this by filling
in some docstrings and add then adding some pointers to existing
modules/functions in the docs.

There's a comment in gdbmi that doesn't adhere to the canonical Python
prompt format.  Fix this.

Rename addr_lookup to address_of to match common terminology more

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.

Some common operations include getting the parent structure of some
embedded field as well as getting "sibling" fields within the parent
structure. Add some convenience methods to the gdbmi module (as well as
wrappers in the RamDump class) for this.

After a crash, ramdumps may be collected for analysis. The ram
parser is a tool to aid in analysis of these dumps. The script
extracts useful information from the dumps to help with debugging.
Please see the README for full details.
