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

Move ipc_logging.py from into the linux-ramdump-parser-v2/parsers
directory, and create a relative symbolic link in the original location.
Add a new file, ipc_logging_ramparse.py, which performs the actual
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
contain anything that allows separate sessions to be distinguished
from one another. Add a line that updates the titlebar of any launched
t32 simulator session with the full path to the RAM dumps being loaded
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

The LPAE MMU code can be re-used for other modules that need page table

that it can be easily re-used later.

Some common operations include getting the parent structure of some
embedded field as well as getting "sibling" fields within the parent

Add support to RamDump.virt_to_phys for automatically looking up
addresses of symbols when a string is passed in. This will simplify code
that uses the RamDump.read_* routines.

Old way:

    mydata_addr = ramdump.addr_lookup('data_var')
    mydata2_addr = ramdump.addr_lookup('data2_var')

    mydata = ramdump.read_word(mydata_addr)
    mydata2 = ramdump.read_word(mydata2_addr)

New way:

    mydata = ramdump.read_word('data_var')
    mydata2 = ramdump.read_word('data2_var')

Of course, the "Old way" will still work.

Commit 3d6a90bd
(linux-ramdump-parser-v2: Don't use ram start address in socinfo)
corrected the case for --auto-dump detection but broke the case of
specifying ram files manually with addresses. When specifying the
addresses manually, the addresses given are correct so the ram start
does need to be added. Correct the code to add the offset by default
but not add when doing autodetection.

When reading soc info, the ram information has not yet been fully
plumbed into the parser (this is very early!). We should not take
the address for the start of ram into account at this point as smem

When adding a new board, it can be non-obvious what went wrong if the
