Deomid Ryabkov e3282a0cac Add esp_intr_set_in_iram 
A function to change "in IRAM" status for an existing interrupt handle, without going through free/allocate of the interrupt.
mOS HW timer implementation requires this to make HW timers safe to re-set from an IRAM ISR.

michael c82e51cf79 fix(intr): always assign the same intr to a same source, disable the source only when all the handlers disabled. 
also document handlers sharing a same source.

TW#13454, https://github.com/nodemcu/nodemcu-firmware/issues/1874

Breaking change: handles assigned to a same source should have the same flag now.

Alexey Gerenkov 8d43859b6a esp32: SEGGER SystemView Tracing Support 
Implements support for system level traces compatible with SEGGER
SystemView tool on top of ESP32 application tracing module.
That kind of traces can help to analyse program's behaviour.
SystemView can show timeline of tasks/ISRs execution, context switches,
statistics related to the CPUs' load distribution etc.

Also this commit adds useful feature to ESP32 application tracing module:
 - Trace data buffering is implemented to handle temporary peaks of events load

Jeroen Domburg 9dc908d105 Add test for local interrupts, fix int disable code 2016-12-08 12:39:33 +08:00
Jeroen Domburg ae8c37e0b6 Add disabling/enabling of shared interrupt, add testcase for interrupts 2016-12-08 12:39:33 +08:00
Jeroen Domburg 655fd2986a Add interrupt allocation scheme / interrupt sharing. Also modifies drivers and examples. Also allows interrupts 
to be marked specifically as having a handler that's all in IRAM.
