This patch series is based on Amerigo's v2 but it now uses a bitmap
for port reservation.
I've ran a while (1) { bind(0) } test (with ip_local_port_range
1024 65000) to see if there is any performance difference between the
two approaches (ranges vs bitmap). I could not detect any significant
difference, both cases scored in 2.76s +/- 0.01 on my setup.
I've based this patch series on current net-next, but it contains a
significant non networking part. Please let me know if I should handle
this differently.

sysctl: refactor integer handling proc code
sysctl: add proc_dobitmap
net: reserve ports for applications using fixed port numbers
