* Functions for setting and clearing interrupts
as well as function to read interrupt mask
should be clearer now.
* Using hal layer interrupt set and clear
functions in esp_wifi component
SoC level exceptions such as watchdog timer and cache errors are now supported.
Such exceptions now triggers a panic, giving more information about how
and when it happened.
esp_system: removed repeated interrupt allocator code and moved common code to esp_system
xtens: moved xtensa specific code from freertos to the xtensa component
hal/interrupt_controller: added interrupt controller hal and ll files
docs: update the doxyfile with new location of esp_itr_alloc.h file
xtensa: fixed dangerous relocation problem after moving xtensa interrupt files out of freertos
docs: removed Xtensa reference from intr_allocator api-reference
xtensa: pushed the interrupt function that manages non iram interrupts to the xtensa layer
esp_system/test: fixed platform dependent setting for intr_allocator tests
hal: rename the functions used to manage non iram interrupt mask.
