Add a forward declaration for the implementation-dependant Timer struct to avoid build failures on the ESP32. Signed-off-by: Denis Benato <[email protected]>
Platforms using LwIP needs to use the "linux" implementation of networking. Not every platform using LwIP has support for every linux primitives/syscalls (such as signal). To allow the adoption in these kind of devices split the network from OS primitives. Signed-off-by: Denis Benato <[email protected]>
The esp-idf SDK requires components (including the main software sources) to be declared with idf_component_register: use that if ESP_PLATFORM is detected. Signed-off-by: Denis Benato <[email protected]>
The lwIP library does not generate SIGPIPE and platforms supporting lwIP might not have a valid implementation of signal: avoid using signal in these circumstances. Signed-off-by: Denis Benato <[email protected]>

ESP32 platform requires the usage of linux sockets with FreeRTOS primitives alongside the usage of idf_component_register.
Split the code in MQTTFreeRTOS and MQTTLinux to be able to use the Linux network code with the FreeRTOS OS primitives handling.
Also modify the CMake file so that the only required step is to clone the repo in the project components directory.
