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)

esp32: update wifi lib to enable ebuf sanity check
The wifi ebuf sanity checking is disabled by default, this MR is to enable it by default. If we detect the last 4 Bytes of ebuf is not DEADBEEF, we assert the system, with the sanity checking, we can detect the ebuf memory corrupt easy.

- fix null pointer dereference in VFS when VFS implementations are added
and removed in different order
- vfs_fat_sdmmc, vfs_fat_spiflash: pass correct drive to mkfs
(previously it would always do mkfs in the first drive)
- add test case
This change moves actual test code into test_fatfs_common.c and
refactors setup/teardown code to be contained within separate functions.
For each SDMMC FATFS test, identical test is added which can run with
WL partition in flash.
vfs_fat_link opened two files to perform copy operation. File structures
were allocated on the stack. When _MAX_SS setting was increased in
ffconf.h due to wear levelling feature, the size of these structures
increased to ~4k each (~8k total). This exceeds stack size allocated for
tasks in most typical cases.
This change makes file structures dynamically allocated.
Originally, prepend_drive_to_path was designed to be a macro, and it
modified local path variables to point to a temporary buffers.
When it was converted into a function, modification to path variables
were no longer visible outside of this function.
In addition to that, prepend_drive_to_path allocated 2k bytes on the
stack for temporary path buffers. This is replaced with path buffers
allocated as part of vfs_fat context object. Locking is added around
parts of code which use these temporary buffers.
Additionally, _lock member of vfs_fat_ctx_t was placed after the
variable-sized files array, which caused the first entry in the
array to be never used. This change fixes the order of members
and adds comments.

esp32: select 8M clock as RTC_FAST_CLK on startup
Even though RTC_CLK_CONFIG_DEFAULT correctly had RTC_FAST_FREQ_8M as the
fast clock, the bootloader modified fast_freq field to the currently
selected RTC_FAST_CLK (so that the clock choice is not affected by the
bootloader). The application startup code never switched to 8M clock,
which caused the default (XTAL/4) to be used as RTC_FAST_CLK. This had
caused a number of issues, such as touch pads not working in deep sleep.
Fixes https://github.com/espressif/esp-idf/issues/542.

Assert when a new task is started on a nonexisting CPU
Previously, starting a task on a CPU ID higher than the amount of CPUs FreeRTOS is configured with would not start the task and possibly have unintended side effects due to some out-of-bounds array writes. Assert on this so the app aborts cleanly.

esp32: update WiFi lib for ebuf sanity check fail issue
By default the WiFi canary check is disabled, before release 2.1, we only have canary check for AMPDU, in release2.1, we add sanity check for all kinds of dynamic ebuf, the checking is disabled by default for performance reason. We found some kinds of packets can't pass sanity check, this MR is to fix it.

esp32/lwip: adjust some lwip options and update wifi lib
1. Modify TCP TX window from 2 to 4 to keep RX/TX window same size
２. Modify TCPIP task stack default size from 2048 to 2560 to avoid stack overflow
３. Update wifi lib for TCP performance optimization

Fix SPI master CI test
CI test fails because the values it checks haven't been updated to the changes in the clock calculations. This fixes that.
