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.
1. fix some bugs in bluetooth sniff mode in controller
2. export some symbols to esp32.rom.ld including functions and global variables in ROM code
3. update libbtdm.a which includes "IRAM_ATTR" addition or removal for some functions

IDF built app download config may change with some modification.
save the download configs for built APP in build stage.
then we can use the correct download config in test stage.
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.

Feature/btdm ble bt separa
@Jack @snake @igrokhotkov @angus @island please help to review the code.
Separate the bt/ble code. After the separate, can save 15k~25k ram & 240k~460k code size(depending on the menuconfig).

optimize scan before station connecting to AP
1. Store the information of AP(ssid, password, bssid, channel, etc)
into nvs when station connects to AP successfully. If station
connects to the same AP next time, it will scan the stored channel of the AP
first.
2. Add a parameter of channel for scanning before connecting to AP.
If the channel is set to 0, station will scan full channels. If it
is set to 1~13, station will only scan the channel.

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.
