- Get Rid MD5 support

Deprecate all non-default Fedora based linux_base respectively linux-fx-*
ports. All of them are End of Life (no security updates) since a loooong time.

As they are not the default, I decided to go with a short expiration date (one
month). The maintainer of the few ports which depend upon the f8 infrastructure
is informed to take action (update to the default f10 infrastructure, or to
deprecate).

. add CONFLICTS to linux-f8 infrastructure ports;
. bump PORTREVISIONs.

Here are new Linux Fedora 8 infrastructure ports.

The recommended version of FreeBSD to use them is 8-CURRENT.
FreeBSD-7.x is not fully compatible with compat.linux.osrelease
2.6.16. Some syscalls cannot be MFCed due to native FreeBSD
ABI breakage.

Usage (and package building):
1. define compat.linux.osrelease=2.6.16;
2. add following variables to /etc/make.conf:
   . OVERRIDE_LINUX_BASE_PORT=f8;
   . OVERRIDE_LINUX_NONBASE_PORTS=f8.

Approved by:    bsam (me) ;-)
