Enable checks for encrypted flash in OTA
Even if firmware is compiled without CONFIG_FLASH_ENCRYPTION_ENABLED.
Rationale: CONFIG_FLASH_ENCRYPTION_ENABLED controls whether boot loader generates keys for encryption or not, but flash encryption can be configured externally. With this change, it's possible to have boot loader not generate keys but still have encryption working.

Introduce soc component, add source of rtc_clk and rtc_pm libraries
This MR adds parts of the RTC library source code (initialization, clock selection functions, sleep functions). WiFi-related power management functions are kept inside the precompiled library. Most of RTC library APIs have been renamed.
Default CPU frequency option in Kconfig is set to 160MHz, pending qualification of 240MHz mode at high temperatures.
Register header files are moved into the new soc component, which will contain chip-specific header files and low-level non-RTOS-aware APIs (such as rtc_ APIs). Some of the files from ESP32 component were also moved: cpu_util.c, brownout.c, and the corresponding header files. Further refactoring of ESP32 component into more meaningful layers (chip-specific low level functions; chip-specific RTOS aware functions; framework-specific RTOS-related functions) will be done in future MRs.

esp32: initialize cross-core interrupt in single core mode

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.

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.

modify touch pad read function

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.
Expand 'make monitor' support
New 'make monitor' idf_monitor tool for better monitor output. Running 'make monitor' will now:
* Automatically look up code addresses via addr2line and print function, source file, line number in terminal.
* Can reset the ESP32 by typing Ctrl-T Ctrl-R.
* Can run "make flash" by typing Ctrl-T Ctrl-F.
* Can run "make app-flash" by typing Ctrl-T Ctrl-A.
* If gdb stub starts, monitor will automatically run gdb and connect. When gdb exits, ESP32 resets and monitor resumes.
* Exit is still Ctrl-[
Have some more features I'd like to add (log output to file, crash dump support) but I think this is at the point of being useful.
See merge request !565
This change adds a check for the free page count to nvs_flash_init.
Under normal operation, NVS keeps at least one free page available,
except for transient states such as freeing up new page. Due to external
factors (such as NVS partition size reduction) this free page could be
lost, making NVS operation impossible. Previously this would cause an
error when performing any nvs_set operation or opening a new namespace.
With this change, an error is returned from nvs_flash_init to indicate
that NVS partition is in such a state.
make: don’t override TEST_COMPONENTS
When idf_monitor is launched from make, it gets modified `TEST_COMPONENTS`
variable which contains full paths to the test components instead of the
names. This causes `TEST_COMPONENT_PATHS` to be empty and the unit test
app gets built without any test components.
This change introduces an internal `TEST_COMPONENTS_LIST` variable which
gets set either from `COMPONENTS` if `TESTS_ALL` is 1, or from
`TEST_COMOPONENTS` otherwise.
Bootloader makefile is also fixed to avoid propagating `TESTS_ALL` to the
bootloader build step.
