The name symbol_at gives a better idea of what the function does, and it
more closely mirrors the corresponding gdbmi function.

In lieu of a more generic way of reading fields from structures,
introduce another specialized structure field reader for reading C

Pointers can be either 32-bits or 64-bits, depending on the
architecture.  Add an accessor function to abstract this away.

A few reader functions currently assume that a virtual address (a
number) was passed in, but those functions also support reading variable
names.  Resolve the address or name to a virtual address before doing
arithmetic on it.

Some of the return sequences in the memory accessor code are
unnecessarily complex.  Simplify them.

Currently there are "trace" print statements scattered throughout the
code.  These make the code harder to follow and aren't terribly useful.
Remove them in favor of on-demand instrumentation or more sophisticated
debugging methods (like a debugger).

The memory accessor functions that have documentation are using comments

Presently auto-dump option finds DDR base addresses from
statically defined per target meta data in boards.py. This
leads to auto-dump feature fail on different targets, say
with different DDR base and size.

Add support to parse DDR base addresses from load.cmm,
dump_info.txt or ramdump_msg.txt which ever is available in
that order. Fall-back to conventional static populated data
in boards.py if none of them is available.

The ram_dump.kernel_version variable is defined as a list and

Ram dump parser does not support unwinding the stack for NON
HLOS images. In certain cases, we get below exception when
parser tries to dump the context for NON HLOS address. Check

Integrate the IPC Logging extraction script module into
linux-ramdump-parser-v2.

Move ipc_logging.py from into the linux-ramdump-parser-v2/parsers

integration.

The constructor currently used in ramparse.py to initialize the RamDump
object has a very long argument list. This list can be shortened by
passing the options object to the constructor, rather than enumerating
every member of the options object as a separate argument.

Pass the options object to the RamDump constructor instead of passing
each member as a separate argument.

Running launch_t32.bat with newer T32 gives syntax errors without newlines
before "SCREEN=" and "PRINTER=WINDOWS" strings in t32_config.t32. Add
newlines before these strings to avoid T32 syntax errors.

If user specified --force-hardware, then skip the socinfo parsing to
determine the hardware/board information. The user is warned about
using the force-hardware option any way.

Checking for valid swapper_pg_dir in the vmlinux also ensures that
the parsing doesn't trip over when --force-hardware is used along with
a bad or stripped vmlinux.

T32 simulator sessions currently launched from lrdp shortcuts do not

in the session.

hexdump currently prints to stdout.  Although that's convenient for
interactive debugging it's not very useful for re-use in other parts of
the parser.  Return a string instead of printing to stdout.

Also add a usage example.

Currently we only generate scripts that work on t32 on Windows. Add
support for launcher scripts targeting t32 on Linux.

Change-Id: I50a293925e181f1b2370d6f7b0df719facdce18a

Currently our generated t32 launcher script always uses port 20,000 for
intercom. This prevents end users from launching two instances of t32
without hacking up the config file by hand. Randomize the port number to
avoid this (there will still be a chance of collision, but it should be
negligible).

The IOMMU parser currently only supports short-descriptor format page
