lwip: implement lwip critical session with mutex
Currently lwip critical session is based on interrupt, now replace it with mutex

spi_flash: fix race condition in s_flash_op_complete access
Flash operation complete flag was cleared by the CPU initiating flash operation. If the other core was running an ISR, then IPC task could be late to enter the loop to check `s_flash_op_complete` by the time next flash operation started. This would cause a deadlock, as the IPC task would still be waiting for `s_flash_op_complete` to be set (which was already cleared by the next flash operation), while the flash operation task would be blocked waiting for IPC task to set `s_flash_op_can_start`.
If the flag is cleared on the CPU waiting on this flag, then the race condition can not happen.

Fix timing adjustment needed for higher speeds of SPI master bus.
Ref https://github.com/espressif/esp-idf/issues/363 . It was found out the master SPI driver didn't exactly calculate the delay compensation needed, breaking 20 and 26MHz full-duplex mode. This fixes these use cases. We also found out 40MHz full-duplex routed over the GPIO matrix does not work because of a hardware quirk; this MR adds a check/error for that case until we find a workaround.

Add WiFi static and dynamic tx buffer choice
If static tx buffer is selected, WiFi tx buffers are allocated when WiFi is initialized and released
when WiFi is de-initialized. If dynamic tx buffer is selected, WiFi tx buffer is allocated when tx
data is delivered from LWIP to WiFi and released when tx data is sent out by WiFi.
The size of each static tx buffers is fixed to about 1.6KB and the size of dynamic tx buffers is
depend on the length of the data delivered from LWIP.
If PSRAM is enabled, "STATIC" should be selected to guarantee enough WiFi tx buffers.
If PSRAM is disabled, "DYNAMIC" should be selected to improve the utilization of RAM.

make: remove version parameter from git status porcelain option
Version parameter was added in git 2.11, while default git on macOS is
currently 2.10. According to the latest git docs, if the version
parameter is not provided, it defaults to ‘v1’, so removing it doesn’t
change the format.

Fix finding location of ISR stack space for CPU1
Up to now, the CPU1 interrupts erroneously used the area *after* the ISR stack region, leading to bugs in BT Classic. This fixes that.

examples: Standardise naming of files, symbols, etc. in examples
* Use "example" in all example function & variable names,
ie use i2c_example_xxx instead of i2c_xxx for example functions.
Closes#198https://github.com/espressif/esp-idf/issues/198
* Mark example functions, etc. static
* Replace uses of "test" & "demo" with "example"
* Split the UART example into two
* Rename "main" example files to end with "_main.c" for disambiguation

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.)
