Split common SPI stuff out of master driver; add slave driver; add workaround for DMA issue.
This merge req mainly adds a slave device. In order to do this, the original master driver is refactored into common code shared by master and slave modes, and a slave driver is added.
The other things added are:
- Added a workaround for a 'feature' of the ESP32 silicon that can lock up the receive DMA channel in some situations. This can only be fixed by resetting *both* DMA channels. The workaround implemented makes sure that the reset only happens when both channels are idle
- Got rid of the automatic choice between register- and DMA-based transfers. The master (and slave) code will now always go for a DMA transfer if a DMA channel is given, and always go for register-based transfers if no DMA channel is given.
- Add in a bunch of fixes for outstanding Github issues.

wear levelling
This MR adds wear levelling component. It presents an interface similar to the interface of spi_flash and esp_partition. Inside, it stores data inside a partition to in a way that reduces worst case number of erase cycles for any given sector.
Also included are APIs similar to the ones provided for SDMMC to mount FAT filesystem on top of the wear levelling partition. A simple example shows how this API can be used.
Ref TW10338.

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.
add wakeup from touch sensor, and deep sleep example
- add new deep sleep wakeup mode
- change documentation to explain incompatibilities between different wakeup mode, add error checks
- add new ULP instructions necessary for ULP wakeup scenario
- fix issues with I_WR_REG, I_SLEEP, I_END instructions
- add deep sleep example, illustrating the use of timer, gpio, touch, and ULP wakeup triggers

FATFS enable support for multiple drives
Current implementation has drive numbers and paths hardcoded to support
only one FATFS drive. Arduino has it's own SPI driver to allow
compatibility and flexibility. With the MR it is possible to have up to
```_VOLUMES``` drives connected (SPI, SDMMC and others) at the same
time and accessed through VFS

Partition/SPI/OTA docs & OTA new functionality
* Update partition, SPI flash & OTA docs to reflect functionality changes
* Refactor OTA implementation to perform checks mentioned in API doc
* Add new functions to OTA API: esp_ota_get_running_partition() & esp_ota_get_next_update_partition() functions
* Add spi_flash_cache2phys() & spi_flash_phys2cache() functions to support esp_ota_get_running_partition()

1. indicate adv/scan start complete success or failed
2. controller do limit of adv/scan concurrence, so add some codes to report adv/scan start failed or not.
This change adds esp_deep_sleep_get_wakeup_cause, which returns the
source which has caused wakeup from deep sleep.
Similar to esp_deep_sleep_get_ext1_wakeup_status, a function is added
to check touch pad wakeup status: esp_deep_sleep_get_touchpad_wakeup_status.
This function returns the touch pad which has caused wakeup.
ULP and touch FSMs in ESP32 revisions 0 and 1 do not operate correctly
if RTC_PERIPH power domain is force powered on (ESP_PD_OPTION_ON).
Both ULP and touch still work, but clock frequency of the ULP may be
incorrect and touch values may be off by considerable amount. As such,
when these wakeup modes are used, RTC_PERIPH power domain has to be set
to ESP_PD_OPTION_AUTO (or, in the current implementation,
ESP_PD_OPTION_OFF — though this will change in the future when _OFF will
actually *force* the power domain to be powered off).
Because EXT0 wakeup source requires RTC_PERIPH to be powered ON, mark
ULP and touch wakeup sources as incompatible with EXT0. Workaround for
this is to use EXT1 wakeup source instead, which offers similar or
better functions without having to keep RTC_PERIPH powered on.
1. add new APIs bt controller enable/disab/deinit
2. make bt controller work need to call two APIs of esp_bt_controller_init and enable
3. modify phy init to make mac reset once
Also add steps to disable flash encryption, as some people seem to
accidentally enable it.
Explicitly mark the flash encryption and secure boot as "READ DOCS
FIRST" in menuconfig.
docs: use custom roles to generate GitHub links
This change replaces direct links to GitHub master branch with
auto-generated links using docutils custom roles.
These auto-generated links point to the tree or blob for the git commit
ID (or tag) of the repository. This is needed to ensure that links don’t
become broken when files in master branch are moved around or deleted.
The following roles are introduced:
```
- :idf:`path` - points to directory inside ESP-IDF
- :idf_blob:`path` - points to file inside ESP-IDF
- :idf_raw:`path` - points to raw view of the file inside ESP-IDF
- :component:`path` - points to directory inside ESP-IDF components dir
- :component_blob:`path` - points to file inside ESP-IDF components dir
- :component_raw:`path` - points to raw view of the file inside ESP-IDF
components dir
- :example:`path` - points to directory inside ESP-IDF examples dir
- :example_blob:`path` - points to file inside ESP-IDF examples dir
- :example_raw:`path` - points to raw view of the file inside ESP-IDF
examples dir
```
A check is added to the CI build script, which searches RST files for
presence of hard-coded links (identified by tree/master, blob/master,
or raw/master part of the URL).
This check can be run manually: cd docs && make gh-linkcheck
Additionally, Sphinx linkcheck build type is used to create new CI test,
which check for broken links. This test has to be triggered explicitly,
because including it in normal build process (when the commit is not yet
deployed to Github) will not work. It can be triggered in a regular
fashion using a combination of cron and Curl, similar to stress tests.
