input_server: Properly implement watch_input_devices() & add documentation

Allow for multiple programs to watch for changes in the state
of input devices connected to the system. Previously only one program
at a time could watch input devices. While this functionality was not
implemented in BeOS R5, it was at least documented in the BeBook.

Also added some API documentation where necessary for the function
and related constants.

Live update of Input preferences device list

- Implement watch_input_devices in input_server, as it was TODO. For
now, only one watcher is allowed at a time.
- Use it in Input preferences to get notified about added and removed
devices and update the device list accordingly.

Consolidate adding add-on directories

This builds off of hrev46243 adding add-on directories all in one place
in AddOnMonitorHandler instead of repeating the code 3 times in
IndexServer, AddOnManager, and MediaAddOnServer.

The safe mode checking in InputServer is now redundant since it all
gets funneled into AddOnMonitorHandler::AddAddOnDirectories()
and the safe mode flags are checked there.

We should probably remove the InputServer::SafeMode() method, but,
I didn't want to break anything that depended on it so I left it.

Remove /boot/common for good

* Remove support for the "common" installation location from packagefs,
package kit, package daemon, package managers.
* Rename the B_COMMON_*_DIRECTORY constants referring to writable
directories to B_SYSTEM_*_DIRECTORY.
* Remove/adjust the use of various B_COMMON_*_DIRECTORY constants.
I'm sure some occurrence still remain. They can be adjusted when the
remaining B_COMMON_*_DIRECTORY constants are removed.

Use incorrect use of BPathMonitor in input/midi/net server

The B_ENTRY_* constants aren't valid watch flags.

input_server: use a generated cookie instead of pointer

* fixed #8831

64-bit fixes for input_server.

Fix unintentional change that broke input_server in safemode.

The change to this initial index for safemode was brought in with the
flat import of the package manager branch in 323b654 where presumably
more paths were used. With this value selecting either just safe mode
or disable user add-ons would lead to no input_server add-ons being
loaded at all, leading to a system without input.

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.

Eliminate the second add-on monitor looper by inheriting AddOnManger
from AddOnMonitor. This solves a concurrency problem in the AddOnMonitorHandler
implementation which called into AddOnManager private methods on the wrong
looper thread without locking. Would have corrupted memory when unplugging
input devices during input_server initialization (so normally not encountered).
The code paths for adding devices were locking already, since those can be
called from other threads as well and this was anticipated.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@39741 a95241bf-73f2-0310-859d-f6bbb57e9c96

weird.
* Set fHandler to NULL in _UnregisterAddOns(), just in case it is called
twice (which it probably never is... but be defensive).

drop into the debugger when compiling in DEBUG mode.

* Rewrote InputServerDevice.h header.
* Renamed _BDeviceAddOn_ to DeviceAddOn, and put it into the BPrivate namespace.
* Moved the DeviceManager functionality into the AddOnManager - this also
solves a locking issue, as BInputServerDevice::Control() was called in the
context of the DeviceManager before.
* The AddOnManager now uses the BPathMonitor to monitor the devices that
BInputServerDevices ask for - this greatly simplifies the code.
* Got rid of TList.h, and use ObjectList.h instead.
* Added PathList class that has a list of paths with reference count, used by
DeviceAddOn and the AddOnManager.
* DeviceAddOn got an actual implementation that lives in InputServerDevice.cpp.
* Added an experimental BInputServerDevice::AddDevices() that could be used
instead of recursing over devices manually. It replaces the functionality
that was found in the DeviceManager before (this was done implicitely for
all monitored devices).
* Greatly cleaned up and simplified the AddOnManager.
* Also fixed lots of potential errors/leaks when things go wrong.
* Removed the extra locker in AddOnManager - its BLooper lock is now used
instead.
* Replaced PRINT()/PRINTERR() macros in the AddOnManager with TRACE(), and
ERROR(), both now use debug_printf().
* Hopefully this fixes the problem that I don't have keyboard under VirtualBox
from time to time.

Fixed bugs #177 and #180 by adding code to notify the input_server that the
system is shutting down.

For the protocol between the Registrar and input_server I decided to just
re-use the message constant already defined in the input server headers

The code in the input server to notify the InputServerDevices about the
shutdown was pretty trivial.

For the code in the Registrar I'll let some gurus review it to make sure it
fits in with the rest of the code.
