    plug-ins: fix signedness warning with different expectation Win/Linux.
    
    On Windows, accept() wants an int for addrlen but on Linux, it wants a
    socklen_t which is an unsigned int. So we can't just switch to gint as
    proposed in !232 (if we do so, the signedness warning now happens on the
    Linux build instead of the Windows one).
    
    Fortunately it looks like socklen_t is actually typedef-ed to int in
    Windows headers. So let's just use this type, which is much more proper
    anyway as this variable is only used in functions which want this type
    on Linux.
    
    Fixes:
    
    > warning: pointer targets in passing argument 3 of 'accept' differ in signedness
    
    (cherry picked from commit e854de73ee12d0dbcffe95da6322ea84fe6a51a7)
