Several of the fields of the task are not being read out as
'true size'. Use more appropriate functions. At the same time,
factor out the reading of pc/fc/sp into a ramdump specific
functionality since that code may be architectur specific.

The sizes for reading some of the structures of the binary logbuf
do not match exactly. Switch to explicitly sized functions due to
size changes across architectures.

Change-Id: Iae09a069f5cb641c61a63d864ec59d0c8359e65b

The binary logbuf now uses *log_buf instead of __log_buf to find the
log buffer. Correctly dereference the pointer.

When tracing with read_physical, the result of what was read is printed.
The result may contain unprintable characters which wreak havok on
terminals. re-use the cleanupString function which is already in use
in several places to make the output readable.

The return size of read_word may change depending on the architecture.
Add functions to read specific types and sizes.

The 8916 board is now generating ramdumps. Add support to parse
these dumps.

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
should only be given as an offset. Update the calculations.

When adding a new board, it can be non-obvious what went wrong if the
board is not immediately detected. Add an option to trace through
socinfo addresses for a specific board to print out useful addresses
as a debugging aid. Also clean up some error handling, mostly among
the tracing code.

The pagetype info gives useful data but it's helpful to see the data
in other formats that often involve having to do math. Make the parser
do the math of calculating the total number of pages per migrate type
and the total number of pages per order. Additionally, print out the
total number of ram pages with vmstat to make it easier to determine
just how low a system may be on memory.

Full slabs are only stored when CONIFG_SLUB_DEBUG is enabled. Move
the parsing for full slabs to this conditional check.

The logbuf for kernel dmesg logs may be re-sized at bootup to
be non-static. Account for this by parsing the non-static version
which should should also point to the static version.

A recent build has generated multiple badly corrupted dumps. Fix
all the errors found by the unintentional fuzzing.

Red/Black trees are supposed to be trees, not directed cyclic graphs.
Sometimes trees in ramdumps may become corrupted though, resulting in
cycles. Detect these cycles in the tree to avoid looping forever.

The IRQ state is stable and isn't likely to change any time soon.
Remove the version checks which do nothing for now.

Change-Id: I3ba2d4fcde6694c16d5f8b79d26b971341f1acc2

The specification of boards of the parser is not very clean. Re-write
it into an easier to read fashion.

We never check the binaries in and its annoying to see them with a
git/diff. Add generated pyc files to .gitignore

Change-Id: Ie181bc8e278d090d088fc1aaba290ac77f724363

Workqueues may be modified at runtime which can leave them in an
inconsistent state in ram dumps. Check for infinite loops in
workqueue lists caused by this state.

Somewhere along the way we started ignoring the --nm-path and --gdb-path
options. Fix this. Also ensure that the command line options take
precedence over anything from local_settings.py or anything discovered
from CROSS_COMPILE.

Change-Id: I39ff653c7de7fb1de170701b898567c9b2356835

We are currently printing gdb_path when there are issues with
nm_path. Fix this by printing nm_path. Also change local_settings.pyi to
local_settings.py.

Sometimes the slabinfo data structures may be corrupt because of software
error or when the ramdumps were collected. Detect this bettter to
avoid looping forever or going out of bounds.

Older targets use a slightly different version of map around the hole
which has different variable names. Account for this in the code.

Several imports were dropped during code refactor. Re-add them.
