870efdb9d4 bugfix(uart): patten detect function
requirement from github(https://github.com/espressif/esp-idf/issues/805): to provide the position in the buffer of the pattern detected.

requirement from AT application: in AT app, when no hardware flow control is enabled, in some situation the rx buffer might be full, and the terminator “+++” might be lost, we can use pattern detect interrupt to avoid missing the terminator. When pattern detect interrupt happens, it will not send a data event at the same time.

1. Add API to get position of detected pattern in rx buffer
2. Modify UART event example
3. Add comments for uart_flush, add alias API uart_flush_input to clear the rx buffer
4. Modify the way rx_buffered_len is calculated

4052803e16 bugfix(uart): workaround for uart fifo reset issue
Reported from github:
https://github.com/espressif/esp-idf/issues/1219
https://github.com/espressif/esp-idf/issues/1202

After providing a simple code to digital team, they confirmed that this is a hardware bug.

Root cause:
The fifo reset signal is incorrectly connected
If we want to reset tx fifo of UART2, we have to set txfifo_rst bit of both UART1 and UART2
If we want to reset rx fifo of UART2, we have to set rxfifo_rst bit of both UART1 and UART2

Workaround:
we don't use fifo rst bit in driver.

Documentation:
Digital team would update TRM and give more explanation about this issue.

303b9f60db bugfix(uart): set default tx idle num
Reported from:
https://github.com/espressif/esp-idf/issues/703
https://github.com/espressif/esp-idf/issues/917
In uart driver we didn't change the default value of tx idle num, so there would be a delay after tx FIFO is empty.

1. Add API to set tx idle interval before next data transmission. (The UART hardware can add an interval after tx FIFO is empty).
2. Set default tx idle interval to zero.
3. Add hardware disable in uart driver delete function.

9d466de235 bugfix(uart): fix signal glitch on tx pin
gpio_matrix_out function will set output enable for GPIO, seems in gpio_matrix_out there will be a short moment that the chip will output GPIO level.
So we can set GPIO as high before gpio_matrix_out function.

1c60a0450e Merge branch 'bugfix/driver_cleanup_log' into 'master'
drivers: remove file paths from log statements

Function name and error string are usually sufficient to find the place which has triggered an error. 

`__FILE__` macro generates a string which has absolute file name (with our build system), which add many long strings to the program binary.

Also change log tags to lower case to match style used elsewhere.

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.
