bugfix: uart event mismatch
Fix bug of uart frame error and parity error interrupt mismatch in driver code, which will cause the corresponding interrupt can not be cleared correctly, and will finally cause a interrupt watch dog.
See merge request !335
GPIO driver: add per-pin interrupt handlers
1. add ISR handler apis so that users of different layers can hook their own isr handler on different GPIO.
Audio project has different software layers, they need different gpio isr handler for layer instead of processing all GPIO interrupts in one handler.
If this kind of calling a handler from isr is not proper, please kindly point out.
2. add gpio example code.
3. update gpio doc.
See merge request !345
Clarification on documenting examples
Improve documentation of examples with two basic actions:
- include README.md in each example project
- add a link with synopsis in API documentation
This was not clear reading original API documentation template.

freertos: fix dual core issue
This commit try to fix dual issue tw9313 raised by QA
1. Put per-core data into critical session or interrupt disabled/enabled session
2. Idle task may have problem when it terminate the task in both core
See merge request !333
1. The transmitting mode of the packets from LWIP to MAC is changed from synchronous to asynchronous.
2. The receive buf mode : support pointer mode and copy mode.
3. Add get phy status func used to config mac register.
CI: use gitlab repo for bt lib on non master barnch
same as wifi lib, some bt lib might not be pushed to github yet for developping branches

2. Add gpio pull-up for rx pin and cts pin.
