vfs: implement reading from UART
This change adds support for reading from the UART FIFO via the `stdin`.
Useful for simple cases when handling lots of data is not a requirement (e.g. command prompts operated by humans).
`\r\n` -> `\n` conversion is guided by the existing `CONFIG_NEWLIB_STDOUT_ADDCR` configuration option.

fixes for github issues
This MR includes commits from several Github PRs, as well some fixes for issues reported on Github and on the forum.
- compile PHY-related code only when WiFi is enabled
- fix macOS setup instructions
- fix some of the Sphinx warnings
- update docs index, improve structure of the readme-
- wifi: fix typos, rename ESP_ERR_WIFI_NOT_START to ESP_ERR_WIFI_NOT_STARTED
- sdmmc: fix explanation of flash voltage regulator configuration efuses
- sdmmc: change idx num of example
- fix i2c_get_period name
- fix esp_log_level_set function name in docs
See merge request !420
If using WIFI_INIT_CONFIG_DEFAULT, error message will point out lack
of WiFi. Otherwise linker errors on WiFi symbols should help give a
clue as to what is broken.
Piggy-backs on changes in !420, ref github #230#237
Fix panic register dump format
Fix misplaced a printf somewhere causing an enter to be printed after every register in the panic regdump instead of every 4th register.
Fixes https://github.com/espressif/esp-idf/issues/236
See merge request !419
Toolchain detection: Allow for Windows executable name and not-yet-configured toolchain path
Windows executable name based on fix suggested by @krzysztof
See merge request !416
Most of the packages mentioned are only needed for building the toolchain using crosstool-NG, not for the normal ESP-IDF environment.
Mention that pyserial needs to be installed (fixes https://github.com/espressif/esp-idf/issues/229).
- low level on GPIO12 corresponds to 3.3V output, not 1.8V
- add espefuse.py commands to burn efuses
- add XPD_SDIO_REG to the list of efuses which must be set

Feature/new mdns
This is a written from scratch mDNS implementation that supports compression, service and host lookups and service advertisement.

esp32 core dump to flash
1. menuconfig option to select where to store core dump: flash, uart or disable
2. Saving of core dump to flash
3. Partition table definitions files with core dump partition
4. Python scripts to support core dump generation from GDB command line
See merge request !341
The following issues mentioned during MR!341 review were fixed:
1) Core dump test application description
2) Usage of CONFIG_ESP32_ENABLE_COREDUMP_TO_FLASH and CONFIG_ESP32_ENABLE_COREDUMP_TO_UART
3) FLASH_GUARD_START macro usage is fixed in flash API
4) Core dump module logging facility
5) cache util functions doc updated
6) interactive delay before print core dump to uart
7) core dump partion support in build system
component bt:Added the create attribute table method to the new API
GATT Server service table APIs.
Have already modify the style and other things as @jeroen suggestion in other MR(the MR have been closed)

deep sleep related fixes
A few fixes for deep sleep behavior:
- Fix a regression that deep sleep stub crashed if `ESP32_DEEP_SLEEP_WAKEUP_DELAY` option was enabled — the stub called `ets_update_cpu_frequency`, which was recently redefined to be an IRAM function, rather than a ROM one. Fixed by restoring the ROM definition as `ets_update_cpu_frequency_rom`, and using that in the deep sleep stub.
- By default, don't power down RTC_SLOW_MEM if there is any data in .rtc.data or .rtc.bss sections. This provides better out-of-the box experience, as variables attributed to .rtc.data are actually preserved during deep sleep.
- Store boot time in RTC_STORE registers instead of using a variable with RTC_DATA_ATTR. This allows RTC_SLOW_MEM to be powered down in deep sleep if no variables with RTC_DATA_ATTR are present in the program.
Fixes https://github.com/espressif/esp-idf/issues/182
See merge request !409
Deep sleep stub may call ets_update_cpu_frequency, which has been moved from ROM to IRAM.
Restore the ROM version in the linker script, call it ets_update_cpu_frequency_rom, use it in the deep sleep stub.
fix mbedtls unit tests, fix IDF_VER when building a project outside ESP-IDF tree
- mbedTLS test needs about 5% more time to run (in debug mode) when building with 5.2.0, compared to 4.8.5. Increase the timeout to let the test pass.
- when doing `git describe` in IDF_VER definition, `-C $(IDF_PATH)` is needed to get the version of ESP-IDF, and not the project being built (which may not even be in git)
See merge request !411
1) PS is fixed up to allow GDB backtrace to work properly
2) MR!341 discussion: in core dump module: esp_panicPutXXX was replaced by ets_printf.
3) MR!341 discussion: core dump flash magic number was changed.
4) MR!341 discussion: SPI flash access API was redesigned to allow flexible critical section management.
5) test app for core dump feature was added
6) fixed base64 file reading issues on Windows platform
7) now raw bin core file is deleted upon core loader failure by epscoredump.py
Complimentary changes:
1) Partition table definitions files with core dump partition
2) Special sub-type for core dump partition
3) Special version of spi_flash_xxx
4) espcoredump.py is script to get core dump from flash and print useful info
5) FreeRTOS API was extended to get tasks snapshots
Clean up WiFi & Bluetooth config options
* Splits "WiFi" configuration out from ESP32 configuration submenu to its own menu.
* Renames "BT" to "Bluetooth", enabling Bluetooth is now in this option not the ESP32 submenu.
* Also disables compiling/linking of BT stack if Bluetooth is disabled, saves some build time.
