Define lwIP's s32/u32 to int (#8560)

Browse Source 
* Define lwIP's s32/u32 to int

s32/u32 were previously defined as long,
but long can be 64 bits in host mode,
so this commit reduces valgrind complaints and increase coherency.

* some lads like to use `unsigned long` for 32 bits IPv4 addresses

* fix lwIP's `sys_now()` return type

* fix C declarations

* merge upstream (lwip2) update on sys_now() definition

* matching lwIP api (2/2)
