The NimBLE host buffers that consume a significant amount of memory are
now allocated dynamically.
The advantage is that, the memory can be reclaimed in cases where BLE
is turned off and not required for the current boot cycle
The interrupt line (DAT1) is an extra pin comparing to SD memory,
allowing the slave to actively inform the host some events.
It's possible for two ESP32 chips to communicate with each other in
1-bit mode or SPI mode without the DAT1 line by polling the slave's
interrupt registers. But this will increase the CPU load of the host,
and do harm to the response speed to slave events.
Python 2 expect the environ variables are all of type 'str', but
sometimes wrong 'unicode' type is given.
Here we force all variables that are not str to become str.
spin_lock: cleaned-up port files and removed portmux files
components/soc: decoupled compare and set operations from FreeRTOS
soc/spinlock: filled initial implementation of spinlock refactor
It will decouple the spinlocks into separated components with not depencences of freertos
an similar interface was provided focusing the readabillity and maintenance, also
naming to spinlocks were adopted. On FreeRTOS side the legacy portMUX macros
gained a form of wrapper functions that calls the spinlocks component thus
minimizing the impact on RTOS side.
This feature aims to close IDF-967
soc/spinlock: spinlocks passed on unit test, missing test corner cases
components/compare_set: added better function namings plus minor performance optimization on spinlocks
soc/spinlock: code reordering to remove ISC C90 mix error
freertos/portmacro: gor rid of critical sections multiline macros, placed inline functions instead
soc/spinlock: improved spinlock performance from internal RAM
For cases where the spinlock is executed from IRAM, there is no
need to check where the spinlock object is placed on memory,
removing this checks caused a great improvement on performance.
SOMAXCONN is expected to be defined in this header, but for the esp32
port is found in net/if.h from newlib.
Avoid the issue by including the net/if.h header in sys/socket.h so that
compatibility is preserved.

Some applications (i.e. Azure IoT SDK) are expecting this header to
exist and to contain the tcp constants and description.
The esp32 did not wrap the lwip/tcp.h header, thus this commit adds a
compatibility layer.
