Add the INCLUDE_CONFIG_FILE option to all config files. In config
files that are generic (ie, GENERIC, GENERICSBC, GENERIC32, ALL, or
ALPHA), it is uncommented.

Add commented-out USERCONF option. Mainly useful for install media
and can be optionally enabled based on miniroot and ramdisk size
requirements.

Rename MEMORY_DISK_SIZE (formerly MINIROOTSIZE) to MEMORY_DISK_ROOT_SIZE,
which was suggested by Izumi Tsutsui <tsutsui@ceres.dti.ne.jp> as
being more consistent with what it's controlling...

While I'm here, ditch some excess baggage which is useless for
the RAMDISK kernel.

Don't base this on the GENERIC config file; there's too much
unnecessary bloat in it for an installation kernel.

The ramdisk now needs 1024 blocks.

branches: 1.3.8; 1.3.20;
Include the GENERIC config. file instead of VME147.

Move 'pseudo-device md' from VME147 to RAMDISK, where it belongs.
For some reason, 'pseudo-device vnd' was missing from VME147; added.
