HPCC-8297 Provide a callback mechanism when resizing a row

When using resizeRow to resize a buffer which is registered with the memory
manager, there needs to be a way of atomically updating the memory buffer
variables.  Otherwise you can get inconsistent results or deadlock the
system.

HPCC-8541 - Add examples illustrating calling Python and Java from ECL

Fix some issues with the threading in the python example, and use #option
rather than command line flags to pick up required library.

This example should now work 'out of the box' on a standard linux install.

HPCC-8495 openWorkUnit() should return NULL for a NULL or empty wuid

IWorkUnitFactory::openWorkUnit builds an xpath to open the given
workunit in dali. If a blank wuid is provided, it opens the root
workunits tree as a workunit. Attempting to open null or empty
wuid should fail. By this fix, the openWorkUnit() returns NULL
for a NULL or empty wuid.

HPCC-8577 - Unecessarily slow thor start/stop times

The default frunssh behaviour is to limit concurrent threads to 10
This means the starting process needs to wait until some of the
start slave script complete, before beginning to start others.
There is no good reason the limit is 10 and in general it should
start all in parallel, via option to frunssh.
