The `max_connections` type tracks how many children git-daemon(1) would
spawn at the same time. This value can be controlled via a command line
switch: if given a positive value we'll set that up as the limit. But
when given either zero or a negative value we don't enforce any limit at
all.
But even when being passed a negative value we won't actually store it,
but normalize it to 0. Still, the variable used to store the config is
using a signed integer, which causes warnings when comparing the number
of accepted connections (`max_connections`) with the number of current
connections being handled (`live_children`).
Adapt the type of `max_connections` such that the types of both
variables match.
