* calling TRoster::GetShutdownApps() multiple times with the same lists
leads to problems because the lists aren't emptied first.
* instead we watch the user app launches, add them in the fUserApps list,
and let _QuitApps() iterates through the fUserApps list until it is empty.

Catch a app_server crash in the debug server. Let the registrar restart the app_server and notify all apps.

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.

Flat commit of all changes from package-management branch in svn

* _IsSystemApp() did not work anymore with the new directory hierarchy. It will
now check for the complete path instead of just the prefix. This fixes bug
#3862.
* Made TRoster.h self contained.
* Style cleanup.

The wonders of signals:
* Since the app_server launched the input_server, it would also get notified
when the latter died via a signal - but LinkReceiver could return B_INTERRUPTED
in that case (it didn't check the return value of port_buffer_size()) which
the app_server misinterpreted and quit itself... this fixes the hanging part
of bug #1298.
* But the input_server still wasn't restarted, because the Registrar had it
still listed as being running. Now, the Registrar checks not just periodically
for died teams, it will also check for it when a new application registers
itself. This fixes the rest of bug #1298.
* Removed the old (disabled) R5 style input_server launch mechanism from the
app_server.
* MessageLooper now prints a bit more information when a port is supposed to
have been deleted.
* The default implementation of MessageLooper::_GetLooperName() is now
returning the name of the semaphore of its BLocker instead of "unnamed
looper".

Turns out the whole "active app" mechanism in the registrar wasn't used at all; the
Switcher now works as expected.
* Renamed TRoster::ActivateApp() to UpdateActiveApp(), as the app is already activated
at that point (the registrar only keeps track of it).
* BWindow::DispatchMessage() now calls the new BRoster::Private::UpdateActiveApp()
method when it receives a B_WINDOW_ACTIVATED message.
* Added BRoster::_UpdateActiveApp() which calls the new B_REG_UPDATE_ACTIVE_APP.
* Removed now unused B_REG_ACTIVATE_APP.
* Minor cleanup.

Added some needed stdio.h includes. I don't know what magic was used to compile
these for other people, but they wouldn't compile for me when building the
app_server test environment.

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
(SYSTEM_SHUTTING_DOWN.)

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.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19289 a95241bf-73f2-0310-859d-f6bbb57e9c96

BRoster::Launch() eventually launches the application in question
in several steps:
1. early pre-registration with the registrar ("I wanna launch the
app, make sure noone interferes.")
2. load the app image
3. finish pre-registration with the registrar ("I have launched
the app, here is its team ID.")
4. start app main thread
5. send "on launch" messages to the app (argv, refs, others)

If the app is already running or being launched, 1. fails with a
conclusive error code and returns the team ID and the pre-registration
token of the app. Steps 2 - 4 are skipped and only the messages are
delivered using the team ID returned by 1.

This change fixes a race condition: The failed early pre-registration
request obviously cannot return the team ID, if the other thread
launching the app has not finished step 3 yet. Thus the argv/refs
message would not get delivered and Launch() would not return the
correct team ID.

Now we wait for the pre-registration to be finished in this case, using
the former _IsAppPreRegistered() mechanism, which already provided
such a waiting feature for one request. It has been extended to
accomodate an arbitrary number of waiting requests and renamed to
_IsAppRegistered().

This fixed bug #763.

Fixes that make Haiku build with gcc 4. Mainly out of the following
categories:
* Missing includes (like <stdlib.h> and <string.h>).
* Linking against $(TARGET_LIBSTDC++) instead of libstdc++.r4.so.
* Local variables shadowing parameters.
* Default parameters in function definitions (as opposed to function
declarations).
* All C++ stuff (nothrow, map, set, vector, min, max,...) must be imported
explicitly from the std:: namespace now.
* "new (sometype)[...]" must read "new sometype[...]", even if sometype is
something like "const char *".
* __FUNCTION__ is no longer a string literal (but a string expression), i.e.
'printf(__FUNCTION__ ": ...\n")' is invalid code.
* A type cast results in a non-lvalue. E.g. "(char *)buffer += bytes"
is an invalid expression.
* "friend class SomeClass" only works when SomeClass is known before.
Otherwise the an inner class with that name is considered as friend.
gcc 4 is much pickier about scopes.
* gcc 4 is generally stricter with respect to type conversions in C.

* Now we have a hardcoded list of apps which shall not be terminated on
shutdown (input, app, debug server, and registrar).
* Fixed crashing bug, if the shutdown was aborted before the window was
created.
* The text of the confirmation alert depends on whether we reboot or
shut down.

* Moved TRoster out of the BPrivate namespace. It does no longer appear in
any public header.
* Replaced a good deal of the MessageDeliverer's DeliverMessage() versions
by more general ones using the new interface MessagingTargetSet to represent
a set of targets. This simplifies the usage in cases where the caller doesn't
already have the targets in a supported representation.
* Implemented a first approximation of the shutdown process. There is no
GUI yet. Only superficially tested under R5.
