SVGHMI: update generated xslt

merged

MQTT: fix typo in resub python callback.

MQTT: fix non reconnecting python topics. WIP

Let extensions know when configuration is new, to apply defaults.

Add "new_config" member to CTN, True when config was just created.

MQTT: fix build error when publishing json topic.

IDE: Better xmlclass behavior with simple XML element having no attibutes (simple TAGs).

xsd:choice can sometime lead to such situation when there is no additional data associated to a particular choice.

merged

WAMP: fix secret upload

Removed useless bitmaps

SVGHMI: update generated xslt

SVGHMI: fix build exception when static file directory is missing

Various unrelated code quality enhancements and fixes with no effect on execution.

MQTT: allow publish and subscribe from user python code.

python runtime: fix exception when transfering files with identical content.

SVGHMI: add static file serving feature.

Added two buttons to add and remove files.
Files are stored in project inside a directory named "static",
itself located in svghmi CTN instance files. Exemple :
exemples/svghmi_csv_json_img_table/svghmi_0@svghmi/static/
Files are transfered as "extra_files", but with a prefix
added to their name to avoid conflics.

Make Input widget actionable. Includes example from kraskrom@github.

Merge remote-tracking branch 'origin/python3' into python3

Update README.md

SVGHMI: fix inverted behavior of SuppressBrowserOutput.

Tests: matiec version bump

Update requirements and add minimal non-frozen requirements for developer setup

Merge remote-tracking branch 'origin/python3' into python3

merge

py_ext: CSV Writer output FB interface: ERROR and RESULT are valid when ACK is TRUE.

+ updated svghmi_csv_json_img_table accordingly

IDE: fix exception when changing or resizing comments in FBD

PLCOpen editor: fix exception when using file open dialog

Consequence of wxPython 3 to 4 API changes.

IDE: Fix wrong red wire coloring in FBD, this time for good.

py_ext: fix CSV update happening only once.

py_ext: rework logic CSV reader FB output refresh logic.

Saving with CSV write FB now triggers CSV read FBs to refresh outputs immediately.

py_ext: fix CSV Writer

fix POU logic :
- SAVE is a BOOL
- invocation of py_eval on rising edge of SAVE
- remove save python argument

fix python:
- use no encoding for file open (python2)
- re-use detected dialect if any
- use no "rt+" and truncate since no need to re-sniff dialect for output file
- return "OK" instead of "#SUCCESS", preventing POU logic to ACK result
- support creating new line if writing just after last line
- support appending data on short rows

fix example:
- use a HMI:Button to trigger CSV write instead of HMI:Input +1
- reload CSVs on on each new CSV opened in file browser
- add display of CSV write output

IDE: Fix wrong red wire coloring in FBD

C runtime: move generated erpc interface in separate "service" directory

IDE: Fix PLCOpenEditor (wxPython4 menus) and drop broken PDF doc support.

Extend HMI:JsonTable, create Edit CSV POU, create example, add some doc (#41)

* Extend Jsontable widget, create Edit CSV POU, create example for both

* Add doc for HMI:Image and HMI:JsonTable

* Expand example to include HMI:Image

Tests: matiec version bump for GH workflow

Merge remote-tracking branch 'hggit/python3' into python3

IDE: fix exception when moving FBD elements with keyboard.

Tests: matiec version bum for GH workflow

merge

Tests: extend FOR loop tests in IEC-61131 language test

Modbus: allows modbus thread stack size customization with MODBUS_STACK_SIZE macro.

For example, add "-DMODBUS_STACK_SIZE=0x2000" to target CFLAGS to limit stack size to 128kB

SVGHMI: swap position and range of ForEach widget so that both range and size can be optional.

Tests: add ST FOR loop tests to IEC-61131 language tests

requirements: update eRPC dependency to include subdirectory for Python

C runtime: fix ExtendedCall stub

eRPC: switch to beremiz/erpc fork with no CRC on TCP

Merge remote-tracking branch 'hggit/python3' into python3

IDE: Allow environment variable override in ThirdPartyPath, and use it also for matiec.

IDE: re-use eRPC URI definitions in connector factory.

Preparing for serial and US eRPC connection.

Cosmetic changes

IDE: refactor discovery panel / zeroconf

Bundle ZeroConf listener and interfaces changes monitor into separate module.
Prepare to extend with USB device browsing.

IDE: refactor ERPC URI editor, add serial and USB URI types

python runtime: update ServicePublisher to current Zeroconf API

eRPC: Backward compatibility with runtime versions missing GetVersions extended call.

eRPC: Version bump

python_runtime: fix ExtendedCall register/unregistering.

eRPC: Server closes connection on exception to prevent client to block until timeout when it happens.

Add ExtendedCall to PLCObject as a replacement of RemoteExec and reflect it in eRPC interface.

ExtendedCall is a generic remote procedure call that runtime code can register to and that IDE extensions can call.
For example a fieldbus extension can use ExtendedCall to browse the fieldbus devices connected to the runtime.

Removed dependency in requirements.txt.

- uses https://github.com/cesanta/frozen
- frozen.c is added as a resulting c file in generat_C (fix toolchain_gcc.py as it was breaking dependency checking)
- structured types are converted to C #define, in turn generating json_scanf and json_printf statements

MQTT: WIP, destroys paho client during failure handling at init and at cleanup. Use mutex to protect retrieve.

MQTT: Implements reconnecting in publish thread in case thread is waken-up but client is disconnected.

Note: paho's lostConnection callback got already disabled in previous commit.

MQTT: take C part away from python code for readability.

C lines change a bit because of unnecessary escaping for '\'.
