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()

Feature/add user set mac
1. Add menuconfig for user to set mac address of wifi, bt and ethernet.
2. Add the number of MAC address generated from efuse for user to choose.
3. Add MAC address derive method.

esp32: Fix hardware rng after esp_wifi_stop (second implementation)
Ensures hardware RNG remains enabled at all times.
Reworked version of !534
See merge request !536
Bugfix/fix some default lwip bool options
menuconfig options with bool type should use 'y/n' to set the default value, instead of '1/0'
See merge request !538
lwip: modify dhcp timer granularity from 60s to 1s
Current DHCP granularity is 60 seconds, it's not accurate, it can cause DHCP release/rebind/renew timer
timeout at the same time, also it may renew/rebind/release at wrong time, thus cause problem.
Do not disable clock for generating random number.
1. Do not disable clock for generating random number.
2. And fix the bug that system crashes if call esp_wifi_stop() twice.

1. RTC V214: modify APLL function for the chip of ECO version.
2. Add API phy_close_rf() and use it in esp_phy_deinit() instead of pm_close_rf().
3. RTC V213: fix BT will not work when BT-init is called more than once.
vfs_fat_sdmmc: if card init fails, fail cleanly
This fixes the issue with sdmmc_host not returned to clean state after a failed attempt to mount the card, with no SD card in the slot.

component/bt : add adv/scan start complete event
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.
See merge request !524
component/bt:fixed the write ccc crash bug error
fix the gatt server write ccc lead to the system crash if not initialize the ccc value.
See merge request !515
Optimize or release memory in bluetooth
1. add option to release about 30K from BT if BLE only
2. later BT/BLE will be separated by BT/BLE macro, but this option should use when user make sure that in BLE only mode.
See merge request !520
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.
Fix a scheduling bug
Fixes:
- Trivial bug where in some special cases a task could be started on the wrong core (and would run there for max 1 tick)
- More major bug causing a yield to be done with a mux held.

Fix SPI master transmit length
Tx/Rx length fix from https://github.com/espressif/esp-idf/pull/336
I also added an extra commit in to make use of a define instead of a literal, plus fix a (harmless) off-by-one condition.

Deep sleep fixes
This change fixes extra 24 uA current consumption in deep sleep mode (https://esp32.com/viewtopic.php?f=2&t=1133).
Recent update to libphy/librtc caused another problem that WiFi related parts of RTC are no longer disabled by RTC sleep functions. This means that if WiFi is not disabled by the application before entering deep sleep, extra ~200uA of current would be consumed. This is fixed, and documentation for esp_deep_sleep and SNTP example are updated to mention that applications should take care of disabling WiFi and BT before going into the deep sleep mode.

spi_flash: fix protection issues
This MR fixes the two spi_flash related issues:
- esp_intr_noniram_{disable,enable} not being protected by spi_flash_op_{lock,unlock} in single core mode. This caused a safety assert to be triggered in esp_intr_noniram_disable.
- spi_flash_unlock not being protected by spi_flash_guard_{start,end}. This caused a conflict between SPI0 and SPI1 controllers when accessing SPI flash, manifesting in cache data corruption and IllegalInstruction exceptions, for some flash chips.
See merge request !522
spi_flash_unlock was missing spi_flash_guard_start, which caused cache
to be enabled during unlock operation, causing hard-to-trace crashes
and cache data corruption.
build system: Fix several make & configuration problems
Collection of quasi-related build system fixes:
* Fix issues with "make menuconfig" running twice when no existing sdkconfig
* Fix issues with menuconfig getting into a bad state if "make -jN" and no existing sdkconfig
* Hopefully fix intermittent issue with build system sometimes not picking up all config, leading to missing BT/WiFi libs at compile/link time.
* Fix issues with path resolution on Windows (including in Eclipse)
* Add new BATCH_BUILD variable for IDEs and automated build environments.
See merge request !485
See github #311https://github.com/espressif/esp-idf/issues/311
Should fix weird compiler/linker bugs where config says something is
enabled, but build system says it is disabled.
Particularly noticeable when WiFi/BT libraries fail to
compile/link despite being enabled.
Underlying cause is configuration file regenerating, but component
Makefiles not reevaluating.
Entirely removes the idea that we don't need to generate config for some
targets (like 'clean'). We need valid config for these targets,
otherwise they don't know which files to clean (etc).
