1d05f41a70 UART driver: Fix crash in ISR due to "UART" static array moved to flash
Ref: http://esp32.com/viewtopic.php?f=13&t=546&sid=76ff371ae2b259441a2cf355e96d74b9#p2275

This is a really subtle bug, gcc noticed the UART array elements are read-only so
implicitly moved the elements to .rodata as if it was const. However
this array is accessed from the UART ISR, so has to be in IRAM or DRAM.

a8a51a2786 bugfix/uart_isr_switch_context: add switching context in uart ISR.
1. add switching context in uart ISR
2. remove duplicated #include in uart.c
3. modify example in uart.h(will later add examples to idf/examples)

e452278194 Minor changes for driver
1. remove "\n" when calling ESP_LOGX APIs.
2. modify uart_event_t for uart rx data.
3. use MICRO for uart inverse value
4. add uart_tx_data_t for internal tx function.

3ec23f1b83 Modify as Angus's suggestion:
1. Set XXX_TAG static, remove extern XXX_TAG in uart.h/ledc.h/gpio.h
2. I removed uart_set/get_print_port() functions, these functions are not well tested, I removed them for now.
3. Modify some function names for uart_read/write_bytes
4. Modify uart_write_bytes and uart_write_bytes_with_break.

a6b3be6734 Update UART driver
1. fix bug in ringbuffer.c:
    When return an dummy item, free_ptr might exceed rd_ptr, so the write_ptr would overwrite rd_ptr in this case.
2. Delete UART tx task in buffer mode. UART ISR will copy the data from tx buffer to fifo.

8d6b782327 Modify UART driver:
1. Add a ring buffer for UART TX.
    If the buffer size is set to zero, driver will not use a buffer. But we need a task to send data from buffer to fifo. I tried directly copy data in ISR, but the code looked too long for ISR.
2. Modify the format in uart.h

74aff2b9d2 Update UART driver
1. Use esp_log API for LEDC and GPIO code.
2. Modify some API return value.
3. Add ledc_set_pin() for LEDC
4. Modify typo in uart.h

Questions: In uart driver ISR handler, I used xxxFromISR , like xSemaphoreGiveFromISR, do those FromISR functions need to be put in IRAM?

288f4f63f0 Add UART driver
1. add uart.h and uart.c
2. add ESP_ERR_TIMEOUT in esp_err.h
3. add UART AHB FIFO address in uart_reg.h
4. modify xRingbufferSendFromISR return value in ringbuffer.c
5. add #include "soc/gpio_sig_map.h" in gpio.h
