unwind tables may not be used on all dumps. Support unwinding the
old fashioned way with framepointers.

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.

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.

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.

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

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

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.
