[PATCH] Added configurable timeout to rlm_exec.

[alan buxey]

hi,

2 small things

1) you seem to be adding this exec patch to other places where external
execution of code takes place - eg verification of the EAP cert - was that
intentional?

2)  it appears that you are choosing to set the value to '0' when running
some commands in debug mode - surely not the intention  (or my misreading
of those few lines)....


I agree that the timeout should be configurable.... perhaps, in an ideal world
you could have a minimum and maximum. server starts with minimum value...if
the reply doesnt happen quick enough and theres a failure, it could log the error
and then incremement the value by one second...up until it reaches the ceiling value.
errors messages would then alert admin to the issue and hopefully external systems
fixed before the 'hard' error boundary reached (which is all we have right now..a hard
boundary)
