that the flagged buffer has a special meaning or should be handled
differently.

Also make comparison method take a flag to indicate if it should
check if the second path is a true prefix of the first.

reclaimed nodes hanging until all their children have been reclaimed
and then reclaim everything we can as far up to root as possible.
This is because the file system structures are currently interlinked
in a fashion which would make dotdot lookup based on purely a path
instead of a in-memory node parent member pointer very difficult.
Yes, this deserves a closer look some day.
hierarchy in the in-memory nodes. This allows us to easily do
reclaim, since we don't have to worry about reclaiming a node which
has alive children which might want to dotdot lookup later on.

* make PUFFS_FLAG_BUILDPATH build paths also if dotdot is the case,
and adapt the regular path objects to this
* make nullfs lookup readable because we can now get rid of dotdot

As defined in rtl81x9reg.h, bits of 0x80 and 0x40 in RTK_CFG1
seem to indicate LEDS0 and LEDS1 configuration initialized by
EEPROM settings, and they seem read only on my quick tests with
two 8169S based cards.
