[MEDIUM] add support for SO_REUSEPORT on Linux

SO_REUSEPORT does not exist on Linux but the checks are available in
the code. With a little patch, it's possible to implement the feature,
but the value of SO_REUSEPORT will still have to be known from userland.
This patch adds a workaround to this problem by figuring out the value
for the one used by SO_REUSEADDR.
