RemoteDesktop: Switch connection direction and simplify client.

Instead of the server connecting back to a listening client, make it
into a more traditional setup with the server listening on a port and
the client connecting to it.

The client can now either connect directly, unencrypted and without the
ability to trigger listening and specifying a command, or through SSH,
as before with the possibilty to run a target application and causing
the creation of the listener.

With the direction change, there's only the need for one, local, port
forward with SSH, which simplifies things.

Add help option to RemoteDesktop

RemoteDesktop: fix -c handling.

hrev43649 was not completely merged during the PM merge, add the missing
line.

Fixes #11955.

RemoteDesktop: Fix x86_64 build.

Fixed RemoteDesktop build that has been broken with hrev43319.

* Or more specifically, in 323b65468e58, part of that revision (ie. the initial
import from Oliver).

Filtered flat import of Oliver's svn package management branch

Bring the changes that aren't package management related and the ones
that are but don't take effect as long as they are ignored by the build
system into the master.

Summary of changes:
* Introduce private header <directories.h> with constants for a good
deal of paths that should usually be retrieved via find_directory().
* Replace hard-coded paths by using find_directory() or the
<directories.h> constants (e.g. in drivers and the kernel).
* Add find_directory() constants needed for package management.
* Add __HAIKU_ABI_NAME and B_HAIKU_ABI_NAME macros.
* src/apps/deskbar: BeMenu.* -> DeskbarMenu.*,
DeskBarUtils.* -> DeskbarUtils.*
* Change deskbar menu settings directory from ~/config/be to
~/config/settings/deskbar.
* Other smaller cleanups, changes, and fixes.

Adding RemoteDesktop client. It wraps a port forwarding ssh call to provide
security and compression for the session. This allows to keep these layers
separate from the actual protocol. This needs to be run from the command line,
as it will request ssh auth there. After connecting it will export the needed
env variable and run the specified shell (Terminal by default) on the remote
host to make it connect to the local client app.
