/**
Patchable constant used in the shutdown server. 
Used to calculate the shutdown timer with KShtdwnTimeoutClient.
It represents the base timeout value in microseconds.

The timeout is calculated as:
KShtdwnTimeoutBase + KShtdwnTimeoutClient * numClients,
where numClients is the number of connecting clients.

If the timeout value is;
-1, the timer is not used, the server will wait for all client's registration 
    before executing the shutdown;
0,  the timer expires immediately, the server will execute the shutdown immediately, 
    not waiting for any client's re-registration.
other value greater than 0, the server will wait a certain period of time for the clients' registration 
    and execute the shutdown if the timer expires or all clients re-register.
    
Licensees who wish to alter these patchable constants will need to define 
these ROM build-time macros in their product HRH or IBY files.

The new values must follow the rule:
KShtdwnTimeoutBase >= -1 and
KShtdwnTimeoutClient >= 0.

Otherwise, the server panics with KErrNotSupported.
