The current codeparser cache handling hurts performance badly even
over a couple of cores and certainly on many core systems, it can
spent huge amounts of time in the codeparser cache save functions.
This patch reworks the cache handling so that each parsing thread
saves out its own "differences" file compared to any existing core
cache and then the main bitbake thread picks these up and merges
things back together.
This was tested on systems with small and large numbers of cores
and was found to perform orders of magnitude better in all cases
despite the more complex code.

parsing process
Before this change, the codeparser cache was only being saved for the main
server process. This is suboptimal as it leaves code being re-evaluated at
task execution time and increases parse time.
We use the multiprocess Finalize() functionality to ensure each process
saves out its cache. We need to update the cache save function to be multiprocess
friendly with locking.

To raise the ShellSyntaxError we need to import it's module and reference it
by namespace.

The pysh we're using is modified, and we don't want to risk it conflicting
with one from elsewhere.

For a given input to this code, the output doesn't change to implement a persistent
cache of the data to speed up parsing.

This commit is derived from Chris Larson's checksum work, turned into a
standalone piece of code for parsing python and shell functions.
The deindent code has been replaced with code to work around indentation
for speed. The original NodeVisitor in the ast was replaced with a faster
class walk call.
