Add configure check for -Wframe-larger-than=<size>

It turns out the gcc option -Wframe-larger-than=<size> which I recently
added to the build system is not supported in older versions of gcc.
Since this is just a flag to ensure I keep stack usage under control
I've added a configure check to detect if gcc supports it.  If it's
available we use it in the proper places, if it's not we don't.

Minor fix to ensure tv_depth is there when debugging is disabled.

Add basic README

A simple README with a short summary of the project and a link
directing people to the online documentation.

Remove README

This file is being updated, renamed README.markdown, and moved to
the master branch for githubs benefit.

Update dependency fix-pthreads changes to fix-stack-ztest

This was done becaese fix-stack-ztest was added to the stack
in series after fix-pthreads because fix-stack-ztest depends
on many of the pthreads changes.

Reduce stack used by ztest

While ztest does run in user space we run it with the same stack
restrictions it would have in kernel space.  This ensures that any
stack related issues which would be hit in the kernel can be caught
and debugged in user space instead.

This patch is a first pass to limit the stack usage of every ztest
function to 1024 bytes.  Subsequent updates can further reduce this
