Patch for proper support of dial-in

Here explanation of the patch:

Dial-In doesn't require a USER, btw. without this fix this lead also to a
strange behavior, because it's working after login (because here USER=root in
environment) while not working during booting called by init.

No secret file is required in dial-in case, authentication data is stored in
/etc/ppp/{pap,chap}-secrets.

noipdefault isn't working in dial-in case.

dial-in-case shoudn't accept remote IP address by default.

Note that DIALIN variable already occurs in ifup-ippp, so it is not introduced
by me. But it is not described at all in sysconfig.txt at "IPPP-specific items
(ISDN)".

The feature dialin-server is not supported well in fc3. I suggest this feature
should be added in fc5. Many thanks for the patch

2 additional patches are needed to support channel bundling proper:

Do not set slave device in dialmode=auto for server config:

Do not start ibod in server mode and channel bundling, makes no sense, client
should do that only (it knows the number...)

it's now fixed in initscript-8.15-1 n rawhide. Many thanks for the patch
