ramfs: Correct usage of Nodes in Entry.

* We do not want to set fNode in the constructor but let the invocation
of Link() take care of doing so instead.

* Link/Unlink manipulate linked-lists. Thus it is dangerous to use them
in tandem on the same Node object. Add a check for this.

* Minor cleanup.

ramfs: Add MIT license header to all files lacking copyright info.

OK'ed by Ingo via email.

ramfs: Lots of fixes to the build.

* Store pointers in an addr_t instead of int32, for 64-bit's sake
* Use DebugSupport.h instead of userlandfs Debug.h and remove extra parentheses
* Create a header-only String class based on the userlandfs String and use it
* RecursiveLock instead of Locker.
* Jamfile cleanups and other misc. changes.

It isn't yet adapted to the new VFS API, so the build is still somewhat
broken.

*sigh* svn really messed it up. I supposed one should make sure to run
update on the directory to be copied before doing it, even if it is up
to date.

Anyway: Ported RamFS to Haiku's FS interface. Change set apparently merged
with older changes.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20346 a95241bf-73f2-0310-859d-f6bbb57e9c96

Mmh, apparently I have to check the copied directory itself in first.
