PPP: Port to the new stack.

Signed-off-by: Augustin Cavalier <waddlesplash@gmail.com>

This is a squash of the 42 commits by @mshlyn, as I couldn't find a
way to break them into logical chunks. I did not include these in the build,
as it appears that they only partially work anyway, and much more cleanup is
still needed. However, this is a huge improvement on what was in the tree
before, which looked horrendous and didn't even compile (as it was designed
for the old stack).

Mostly fixes #812.

* Made the PPP code more single-threaded.
* Removed ppp_up code.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@18161 a95241bf-73f2-0310-859d-f6bbb57e9c96

- updated email-address
- removed profiles, ppp_up, and some TODOs
- simplified KPPPReportManager and reports API, KPPPInterface::Up()+Down(), and PPPInterfaceListener (also removed some features from the last one)
- KPPPInterface now sends the last PPP_CONNECTION_REPORT message to every newly registered report receiver
- added net_server to the build, but removed old net_server testing-stuff

all changes are completely untested

DialOnDemand will be handled differently. Instead of setting it manually in the prefs we have one default interface. Still not finished.
Moved ppp_up code to KPPPManager.
Experimenting with IPCP DialOnDemand support.
Many changes I do not remember.

Fixed a couple of possible dead-locks.
Fixed some minor bugs.
PPPoE: added experimental support for AccessConcentrator and ServiceName settings.
Changed libppp to import strlcat.c from libroot instead of duplicating code.

Updated according to name changes in kernel classes.
IPCP and PAP (hopefully) make use of profiles.
Minor changes.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6284 a95241bf-73f2-0310-859d-f6bbb57e9c96

Replaced all printf and spawn_thread functions with their kernel counterparts.
IPCP: changed route initialization a little bit. Still cannot remove default route correctly.
Renamed interface_id to ppp_interface_id.
Some minor changes.
Worked on libppp.a (userland PPP library).


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@6159 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added modem driver (completely untested, currently no support for settings speed because modem API is missing).
Some minor changes.
Added TODO file to almost all modules.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@5768 a95241bf-73f2-0310-859d-f6bbb57e9c96

Fixed many bugs and added debug output.
You can now successfully (dis-)connect to(/from) a PPP server using the PPPoE device module.
To be useful we need the PAP and IPCP modules (in the works).
