sasl: Use gen_server:call/3 with infinity timeout

gen_server:call/2,3 now sets up a monitor to make sure that
it will be noticed if the called process dies. Therefore,
there is almost never a good reason to use gen_server:call/2
with its default 5 seconds timeout. Use gen_server:call/3
with the 'infinity' timeout instead.

To make sure we use the 'infinity' timeout every time,
wrap the to call gen_server:call/3 in a local call/1 function
in each module.
