Now apps should use getters and setters instead of accessing struct
fields directly, e.g. instead of `get_cfg()->update.timeout` it should
be `mgos_sys_config_get_update_timeout()` to get the current value, and
`mgos_sys_config_set_update_timeout(123)` to update the value.

For now, the config structs are public, but they will be made private
soon, so use accessors to keep your code working.

Mongoose would report consumed bytes twice if mg_call is invoked recursively (e.g. proto_handler uses mg_call to invoke user's handler).
Reporting twice as much recved as was delivered effectively disables LwIP's TCP throttling and causes buffers to grow too big.

For now, we only support SPIFFS-in-a-box, same as CC3200.
On CC3200SF it should be possible to have SPIFFS on built-in flash, but that is left for later.
