In the Draw() method check to make sure that the view is valid, is
connected to the window, that the window is locked, that the screen
is valid and that the BBitmap buffer is valid. This (hopefully) fixes the
last of the bugs experienced due to #4260.
It is not sufficient to just check that the view is valid to prevent the crash,
you must also check that it is connected to a window via Window() and
that the window is locked.
* This is primarily a service method for ports of widget tool kits
that require single-threaded GUI. DispatchExternalMessage() calls
DispatchMessage(), but also sets fLastMessage, so that
[Detach]CurrentMessage() work correctly. This allows to detach a
message in DispatchMessage() when called from the window thread,
add it to a global queue, and later process the queued messages in
a different thread that calls DispatchExternalMessage().
* BLooper/BWindow: Make sure fLastMessage is accessed only when locked.
As weak aliases are not supported on OS X, this caused problems when
building Haiku on OS X, as this file is also used for the host tools.

When BWindow receives a message in screen coordinates and the
message has a target view, as it does when the message comes from
App Server, convert the coordinates to view coordinates before
passing the message along.
Revert the portion of hrev46532 where BView converts screen
coordinates and converts them since that happens in
BWindow::_SanatizeMessage() now.
- debug_server now supports user configuration of both the general default
action to be taken on crashes, and per-app overrides. These are stored
config/settings/system/debug_server/settings. In the absence of the file,
behavior defaults to prompting the user for an action as before.
The file takes on a driver_settings style format as follows:
---
default_action user
executable_actions {
app1 log
/path/app2* debug
}
---
Valid values for an action are:
- user = prompt user for action.
- kill = silently terminate the crashing team.
- debug = attach the debugger to the crashing team. in the debugger.
- log / report = save a crash report and terminate the team.
If no default_action is specified, "user" is assumed.
The executable_actions subsection contains individual overrides of the
default. These take the form above, where the individual lines can be
only a team name, or a path, with wildcards.
Implements first part of #10301.
