4719bab2f3 freertos: Bump default idle task stack size to 1536 bytes
In situations where idle task runs a lot of idle hooks or cleanup code
(due to pthread local storage, etc) it can use more than 1KB of stack.

(I think the trigger is if a context switch happens at the right point
in the TLS cleanup).

Also removes an sdkconfig.default which accidentally set all config items,
including this stack size.

0c9e2c0fba esp_adc_cal/Remove lookup table
This commit removes the lookup table mode due to inferior performance when compared
to linear mode under attenuation 0, 1 and 2. However small portions of the lookup table
are kept for the higher voltages of atten 3 (above ADC reading 2880). That voltage range
in atten 3 has non linear characteristics making the LUT performan better than linear mode.

451f69cc2e driver(i2s): fix broken i2s adc mode
1. Move i2s reset code from i2s_stop to i2s_start.
2. add RTC API to set sw mode for ADC
3. add description for adc_power_always_on()
4. add lock for i2s dma and RTC ADC functions.
5. add ADC read task in example

2fceec4d85 feature(I2S-ADC): add ADC mode for I2S.
1. Support built-in ADC for I2S.
2. Modify code of ADC, made no change to the original APIs.
3. Add APIs in I2S:
esp_err_t i2s_set_adc_mode(adc_unit_t adc_unit, adc1_channel_t adc_channel);
4. Add I2S ADC/DAC example code.
5. add old-fashion definition to make it more compatible
6. replase spi_flash_ APIs with esp_partition_ APIs
7. add example of generating audio table from wav
8. change example sound
