Make Modbus extension license compatible with the rest of Beremiz IDE python code : GPLv2.

Commented out safety check to prevent deadlock in wxEvaluator, since wx Mainloop is not anymore in main thread. That safety check actually leads to having wx code running outside of MainLoop

PEP-8 and PyLint

PEP-8 and PyLint

Add safety check to prevent exception when disconnecting while debugging

Removed DebugThread. Take advantage of the fact that buffering is done in runtime. No need to poll for traces more than ten per second, then use simple wxTimer for that. Also removed Debug Lock since now everything happens in wx' mainloop.

Rework of runtime non-real-time threading, and shared object dynamic loading :
- All exposed operations on PLCObject are now serialized through main thread
(@RunInMain). Only one exception : python trace thread calling _GetDebugData
- Re-loading of same shared object is prevented. dlclose/delte/rewrite/dlopen
don't happen in that case. This is a workaround for some xenomai copperplate
bug triggering segfault, inbetween delete and rewrite.
- Trace thread now waits for data, dies if no data, and dies instead of
suspending as before when no data consumed after 3 seconds.
- Disabled threading in Pyro client
- Enforced auxiliary threads starting sequence : Pyro -> [UI] ->
PLCWorker.RunLoop

Stripped forgotten debug code

close branch

#2476 Fix for saving text in URI edit text box. No need to click out of URI edit text box to save edited text.

Fixed Xenomai 3 PLC stop freeze. Now use explicit finish command with pipes. Closing both ends of pipes doesn't abort blocking read anymore.

More canonical test.
There is an exception happening around here in some cases when connection is dropped while waiting for answer. Not sure that this fixes it but this is anyhow better.

PLCObject got more methods serialized through worker : Start, Stop, NewPLC.
This particularly helps with initialization/startup/re-load problems
when targeting Xenomai. It should help in general for runtime robustness,
since those operations aren't meant to be executed concurrently.

Fixed implementation of runtime worker that ensure that PLCObject Load and Unload methods always run main thread.

Intermediate state while implementing runtime worker to ensure that PLCObject Load and Unload methods always run main thread.

Stripped more dead code.

Cleanup of some dead code in PYRO connector.

Added logging in Xenomai init phase.

fix for test app from skv. thanks

Prevent catching exception if exception handling was not enabled (or disabled by test test app).

pep8 and pylint hate me

Fixed typo introduced in 5736d25bb393

GetEditedElementInstancesInfos now optimized as well. Forgotten because not using [R.I.P]LibraryResolver, but still XSLT compiling was hapenning on each call.

Another attempt to make BitBuket's version of pylint happy.

Attempt to make BitBuket's version of pep8 and pylint happy.

Removed dead slow code

PEP8 and PyLint conformance: whitespaces and stuff

Copy pasted, no time wasted !

GetVariableDictionary and GetPouInterfaceReturnType optimized with new VariableInfoCollector based on XSLTModelQuery. Moved corresponding definitions out of PLCControler.py.

GetPouInstanceTagName optimized with XSLTModelQuery.

Better writing of some xpath added in previous commits about XSLT optimization.

Moved some definitions away from controller class, and adaped references them through all code.

Hook Beremiz Launcher AppStart to AdvancedSplash OnPaint event in order to ensure image is beeing displayed before loading.

Avoid endline escaping in multiline xpath epressions in xslt. '&#10;' Is apparently ignored but never know...

Fixed earlier XSLT optimizations. Some/most results were missing.

Moved some code from PLCController.py to other modules. Added necessary imports.

GetPouVariables optimized with XSLTModelQuery

Added /plcopen/InstancesPathCollector.py, to move more model xslt querying code away from PLCController.py.

Fixed Exception dialog disapearing after a view second when exception occurs during app startup.
Problem was caused by splashscreen timeout, wx closing averything else if there is no more main frame.
Changes:
- no more timeout for splashscreen
- use wx.App OnInit method to give first operation to mainloop, object are then now created in mainloop
- main loop is then created _before_ showing splash screen
- no more wxyield or wx processevent tricks needed to display splash screen
- exception handler not blocking anymore on dialog (callafter)
- because of mainloop being there before everything, exit must be called explicitely if exception caught during startup -> exit parameter in handle_exception + try/except around startup calls

UNTESTED ON WINDOWS

Moved XSLTModelQuery class to own module in plcopen package.

Added a class to speedup all XSLT queries. WIP, now only for instances_path.xslt / GetInstanceList()

Stripped useless node creation in instances_path stylesheet.

This should really help GetInstanceList to perform better: resolver removed, no more deepcopy, no more useless xml serialization, no more node-set() calls.

YSLT auto indent trick is useless here, added yslt_noindent.yml2, regenerated XSLT files

Prevent compiling XSLT on each call of GetInstanceList. To be continued. More optimization needed here. 100x would be fine...

Changed meaning of -c commandline argument for Beremiz service : only gives DEFAULT wamp config.
If existing project already has a wamp config, it is taken instead.

Factorized duplicated code

Better variable naming, and small optimization.

Unclutter graphics package scope.
Moved some import statements from "graphics" package to "viewer" module.
It also avoid systematic import of everything in graphics when we only need one submodule.

Removed dead code

Fixed pyro timeout for runtime, was set too short and runtime was disconnecting when building PLC

Ask to stop PLC before transfer if it is running

Factorized some repeated refresh code into a method, to allow customisation.

Launcher : add a debug attribute, instead of BMZ_DBG, so that customization can use it.

Stripped old dead code.

More changes in Launcher. Modules to be loaded in the background are given in a list, and assigned as object attributes. Also splitted CreateUI into CloseSplashScreen and CreatueUI.

ClassImporter now accepts string, callable or class, for compatibility with some old extensions.

Launcher: ShowUI call moves from preStart to start. ShowUI() split into CreateUI() and ShowUI(). Start()'s arguments are passed to CreateUI()
This is meant to allow customizations to pass own pre-instanciated controller to UI at startup.

Launcher: allows customizations to specify what globals passed to extensions

Documentation

Another set of meaningless changes to satisfy PEP8 and PyLint.

PEP8 conformity for modbus. Most of it done by autopep8, plus some easy refactoring.

Add some class factory function to ease declaration of simple POU libraries in customizations (i.e. TC6 XML file only, no special C code generation)

Small pep8 conformity enforcement.

Better have globals passed to python extensions (-e) than locals.

launcher : move call to ShowSplashScreen and BackgroundInitialization to PreStart()
It doesn't change behaviour of launcher in beremiz, but may have some impact on some customizations.
Some customizations need to squeeze some bitmap folder init in between app creation and ShowSplashScreen

modbus extension code cleanup, from smarteh's patch

Merged Mario's modbus branch. Fixed line endings.
