[Lprng-devel] [PATCH] remove arguments from Read_pid and add Read_pid_from_file

Read_pid is never called unless with 3rd and 4th argument 0. Also most
users have the exactly same call pattern, so moving that into a new
function make the other functions a bit easier to read. (Especially as I
am trying to change some connection handling, where using the same fd
variable for different things in the same function tends to be a bit
confusing.)

Only non-triviality is that some code had pid = -1 per default, other =
0. This patch should contain everything to cope with that.
