FATFS fixes and tests
This MR includes a set of fixes related to FATFS, SDMMC, and wear levelling:
- `esp_vfs_fat_spiflash_mount` uses `FM_SFD` flag when creating the partition. The volume layout (given in `VolToPart` variable) was not compatible with SFD mode, so mkfs was failing. This fixes the volume layout to use "autodetect" for both volumes. Merges https://github.com/espressif/esp-idf/pull/559.
- fix `prepend_drive_to_path`function, which didn't prepend drive to path (while consuming 2k of stack space)
- fix stack overflow in vfs_fat_link function which allocated two 4kbyte `FIL` structures on the stack
- fix support for having two FATFS instances (in flash and SD) mounted at the same time
- unit tests written for FATFS on SDMMC are made common between SDMMC and WL implementations; FATFS unit tests on WL will run during CI
- fix inconsistent definition of PATH_MAX and ARG_MAX (TW12207, TW12104, https://github.com/espressif/esp-idf/issues/289)

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.

- Implements application tracing module which allows to send arbitrary
data to host over JTAG. This feature is useful for analyzing
program modules behavior, dumping run-time application data etc.
- Implements printf-like logging functions on top of apptrace module.
This feature is a kind of semihosted printf functionality with lower
overhead and impact on system behaviour as compared to standard printf.
Windows setup improvements
* Tweak Makefile to significantly reduce startup time on Windows (also reduced on other platforms, but less obvious.)
* Revise windows setup installation script to fix various issues, use latest toolchain.
* Tweak Windows config docs

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.)

* "make monitor" not passed the configured baud rate
Closes#436https://github.com/espressif/esp-idf/issues/436
* Pass toolchain prefix from sdkconfig into monitor tool
* Allow setting EOL in idf_monitor.py, use CRLF by default
* Detect if /dev/tty.X is used on macOS, warn and replace with /dev/cu.X
* If a build fails or gdb exits, ignore Ctrl-T (allowing Ctrl-T Ctrl-A/F to be same key sequence everywhere)
* Add a note about winpty on Windows

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.

unit tests: Make UnitTestParser ignore non-directories inside 'components' dirs
Tiny fix to UnitTestParser script behaviour, if you happen to have any stray files in your "components" directories.
See merge request !561
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()
See merge request !513
Add python script that parses list of unit test cases for CI from component test folder
Modify .gitlab-ci.yml to run this script as part of build unit tests stage
Create temp config in the same dir as target
Fixes case where SDK and app are on different mounts
(In our usage of kconfig, dirname is the empty string & basename is the full path to sdkconfig)

Add dynamic interrupt allocation mechanism
This adds:
- Dynamic allocation of interrupts. Pass it the features of the interrupt you want, it'll set you up with an int.
- Shared interrupts. Enables multiple peripheral drivers to use the same interrupt.
- Marking what interrupts are fully executable from IRAM; if an int isn't marked like that it will get disabled once flash cache gets disabled.
Also:
- Modifies driver to be in line with these changes
