CI: add reset between running each unit test cases
Unit test is designed to detect bug **within** each test case. Therefore we'll reset between each case to provide a clean context. We will later add stress cases to run unit test cases together to detect potential bugs.

esp32: initialize cross-core interrupt in single core mode
The software interrupt originally used as the cross-core interrupt is
now also used to yield from a FreeRTOS critical section; therefore it
must be initialized for single core mode as well.

fix warnings generated by ESP_ERROR_CHECK(variable) in release builds
This uses the same pattern as “assert” in release builds to silence the
warning. At the same time, we make sure that if a statement is wrapped
into ESP_ERROR_CHECK, it is executed in release build as well.

spi_flash: fix race condition in s_flash_op_complete access
Flash operation complete flag was cleared by the CPU initiating flash operation. If the other core was running an ISR, then IPC task could be late to enter the loop to check `s_flash_op_complete` by the time next flash operation started. This would cause a deadlock, as the IPC task would still be waiting for `s_flash_op_complete` to be set (which was already cleared by the next flash operation), while the flash operation task would be blocked waiting for IPC task to set `s_flash_op_can_start`.
If the flag is cleared on the CPU waiting on this flag, then the race condition can not happen.

Fix timing adjustment needed for higher speeds of SPI master bus.
Ref https://github.com/espressif/esp-idf/issues/363 . It was found out the master SPI driver didn't exactly calculate the delay compensation needed, breaking 20 and 26MHz full-duplex mode. This fixes these use cases. We also found out 40MHz full-duplex routed over the GPIO matrix does not work because of a hardware quirk; this MR adds a check/error for that case until we find a workaround.

If static tx buffer is selected, WiFi tx buffers are allocated when WiFi is initialized and released
when WiFi is de-initialized. If dynamic tx buffer is selected, WiFi tx buffer is allocated when tx
data is delivered from LWIP to WiFi and released when tx data is sent out by WiFi.
The size of each static tx buffers is fixed to about 1.6KB and the size of dynamic tx buffers is
depend on the length of the data delivered from LWIP.
If PSRAM is enabled, "STATIC" should be selected to guarantee enough WiFi tx buffers.
If PSRAM is disabled, "DYNAMIC" should be selected to improve the utilization of RAM.
Fix finding location of ISR stack space for CPU1
Up to now, the CPU1 interrupts erroneously used the area *after* the ISR stack region, leading to bugs in BT Classic. This fixes that.

SPI flash operations lock for shorter periods
Based on bug report here:
https://esp32.com/viewtopic.php?f=13&t=1489&p=6816#p6773
Long SPI flash erase (and possibly write/read) cycles block all tasks on both CPUs for an extended period, and can lead to WiFi dissassociation (and general priority inversion.)
This MR inserts preemption breaks into large operations (all erases, writes every 8KB, reads every 16KB).
Overhead of a single spi_flash_guart_start()/spi_flash_guard_end() cycle measured at approx 67us (assuming no preemption.)

Error handling in NVS initialization
Previously nvs_flash_init worked under an assumption that there should always be at least one free page available. This is true during normal operation, but in some cases (such as when changing application partition table from a non-OTA to an OTA one), NVS partition may get truncated, which will cause empty pages to be lost.
This MR adds error checks for this condition, and updates code which calls `nvs_flash_init` to check for the return code.
For most examples, a simple `ESP_ERROR_CHECK` is added around `nvs_flash_init`. For NVS examples and the OTA example, more robust error handling is added.
This change also removes nvs_flash_init calls from examples which don't use NVS.

idf_monitor: Small fixes (baud rate, EOL, /dev/tty.X on macOS, Ctrl-T on failure)
* "make monitor" now passed the configured baud rate.
Closes#436https://github.com/espressif/esp-idf/issues/436
* Pass toolchain prefix from sdkconfig into monitor tool
* Allow setting EOL in idf_monitor.py, use CRLF by default
* Detect if /dev/tty.X is used on macOS, warn and replace with /dev/cu.X
* If a build fails or gdb exits, ignore Ctrl-T (allowing Ctrl-T Ctrl-A/F to be same key sequence everywhere)
* Add a note about winpty on Windows.

* Erase range operations allow preemption after each block or sector.
* Write operations allow preemption every 8KB of data.
* Reado operations allow preemption every 16KB of data.
This is to avoid confusion when idf_monitor prints the first symbol in each section, ie "WindowOverflow4" or similar,
when bootloader prints the section mapping address.

modify touch pad read function
The touch pad read function taks too much time within spin lock waiting for the "done bit". (about 7.6ms as we tested)
So we try to use a mutex on the touch read function and any other functions might change the "done bit".

This issue is reported from https://github.com/espressif/esp-idf/issues/304.
We found that when we operate the hw command registers in I2C struct, sometimes the behaviour would be different in DEBUG/RELEASE optimisation level:
The code looks like this:
I2C[i2c_num]->command[p_i2c->cmd_idx].byte_num -= 0;
In DEBUG configuration:
I2C[i2c_num]->command[p_i2c->cmd_idx].byte_num -= 0;

Looks like the compiler will make it a 8bit operation after optimisation.
But the register value changes from 0x901 to 0x101.
After this 8-bit optimisation, the 11th bit changed from 1 to zero, which caused this error.
We are still trying to find out why that happens, because there might be some risk when operating the register struct.
This is a workaround to avoid "-=" operation on I2C register struct fields.
1. Add low speed channels for LEDC module.
2. Improve fade object allocate mechanism.
3. Improve ledc example, add 2 low speed channels in example.
4. Remove debug code
5. Improve the register bit field name of slow clock.

nvs_flash_init may return an error code in some cases, and applications
should check this error code (or at least assert on it being ESP_OK, to
make potential issues more immediately obvious).
This change modifies all the examples which use NVS to check the error
code. Most examples get a simple ESP_ERROR_CHECK assert, while NVS
examples, OTA example, and NVS unit tests get a more verbose check which
may be used in real applications.
