- Keep a history of active runway for each class, so that runway assignments

- just not on Linux - the linker wants to know about _all_ required
libraries. So even if a shared library "libosgViewer" itself is linked
against "libosgGA" and "libosgText", you still have to name these in
order to build an "fgfs" binary.
Currently, other libraries like "-losgDB" and "-losgUtil" are
explicitly mentioned on the "fgfs" linker command, but "-losgGA" and
"-losgText" are not. This simple patch lets the linker honour
everything that's required

I refactored the XML loading code out of FGAirportDynamics and
FGRunwayPreference. I also added a new class XMLLoader, which serves as a
facade to the loader functions. Further I changed FGRunwayPreference to just
keep a FGAirport ref, which is more concise and closer to the right(tm)
solution than storing the airport data a second time ;-)

Usage: parsexml(<path> [, <start-tag> [, <end-tag> [, <data> [, <pi>]]]]);
<path> is an absolute file path, the rest are optional callback functions.
Example:
parsexml("/tmp/foo.xml", nil, nil, func(d) { print("DATA FOUND: ", d) });
where type is one of string (default), double, float, long, int, bool
Using only the first letter works, too.
--prop:foo=123 ... sets property foo to string 123 (old behavior)
--prop:string:foo=123 ... verbose version of above
--prop:s:foo=123 ... slightly less verbose version of above
--prop:bool:foo=1 ... makes property a bool of value 'true'
I hope this isn't considered a silly gimmick. I need this often and maybe
other developers do, too. It's useful in cases where the difference really
matters. if (getprop("/foo")), for instance, is TRUE even when the property
contains string "false", as all strings are TRUE.
efficiently performing "Dijkstra algorithm".
Durk Talsma: Added the detection of "circular" wait situations in the AI
ground network. A circular wait is a situation where aircraft a waits for
b; b waits for c; and c (in turn) waits for a. The checkCircularWaits
function detects these situations.
The current "solution" to a circular wait is rather crude: Remove the
aircraft from the scene. A proper solution needs a lot more work, however,
and at least this patch stops the AI system from clogging up. in case of a
circular wait.
data for AI traffic. Default performance classes are still available as a
backup. This database will allow the calculation of aircraft-specific
take-off speed and estimate runway lenght requirements. Further added
rudimentary support for take-off and landing rotation of AIAircraft.

or nil if no terrain intersection could be made (tile not loaded yet).
<matdata> is a hash with information about the surface material, or nil
if no material is assigned (shouldn't really happen, but one never knows).
Example:
var ac = geo.aircraft_position();
var data = geoddata(ac.lat(), ac.lon());
debug.dump(data);

/sim/screneryloaded-override was "true". At least one subsystem (od_gauge)
waits for /sim/sceneryloaded to bypass CPU intensive code until the scenery
is up. This broke e.g. the RTT-radar when using /sim/screneryloaded-override
--prop:sim/sceneryloaded-override=true has the effect that fgfs
doesn't show the splash screen until the scenery is loaded, but shows
the OTW view (scenery/aircraft) at the earliest possible moment. This is
useful for developers who often need to run fgfs only to check some minor
detail, while not caring about stuttering caused by scenery loading.
simple SG_LOG instead. The user didn't call the fgcommand, so why should
s/he be bothered with that? And the actually caller of the command gets a
return value and can pop up a dialog if it thinks it's necessary.
Why /sim/fg-current at all? Because we have a file selector dialog
(still unfinished), and one might like to start it from the current
directory, to find saved flights/screenshots/whatever.

may be unprepared for it. So basically this is now yet another way
you can use Nasal to exercise bugs and hose your sim; no biggie.

at all is that this method is meant to be deprecated. But if it doesn't
say that, and there's no generic replacement at all, then it's rather
pointless.
- simplify parameter initialization (The old code copied from Instrumentation/

The new method is less picky about additional nodes ane outputs less
pointless alerts. If there shall really be a check for that, then
this should be a separate function. But it's nowhere else done in fgfs.

- use SG_LOG instead of cerr

by compiling fgfs/sg without exception support (unlikely) or linking
against a libSDL/libglut that was compiled/linked without execption

show "secret" values, that is: values of nodes with children. These

number of attached listeners. Example: foo = 'bar' (string, AU, L3).
dialog.cxx: add warning message for broken <format>s; cosmetics
- props is easy to mix up with the --prop option (for setting properties)
- the name is unspecific and inconsistent: other option names describe
the protocol -- the way to get the properties. How is, for example,
--httpd less about prop(ertie)s?
- two identical options easily confuse people, as can be seen in The
FlightGear Manual, where --telnet and --props were described differently
/sim/view[*] that it finds. It's not only unnecessary that view definitions
have subsequent indices, but aircraft are now *requested* to use indices
100++. /sim/view[0] .. /sim/view[99] are reserved for the system. (Not
that we'd ever need that many, This is just a convention, it's nowhere
hard-coded.)
- replace the string operations for property paths by method calls & other
improvements
because nasal's f_interpolate() may be called in Nasal at times when the
GENERAL subsystem group is being deconstructed; access it by addressing
the group directly, as using globals->get_subsystem() does then not
work any more then; yeah, it's all for a rare border case ... :-)
NasalSys.cxx more robust instead. The reason for the crash was that during
fgfs shutdown destroyed subsystems (GENERAL group) still need Nasal access
(for AI Model destruction listeners), but at that point globals->get_subsystem()
can't even deliver the "nasal" subsystem (INIT group). One way to solve that
problem would have been to replace globals->get_subsystem("nasal") by
globals->get_subsystem_mgr()->get_group(SGSubsystemMgr::INIT)->get_subsystem("nasal"),
but Andy decided to store a pointer to the active "nasal" subsysten in
NasalSys.cxx instead, as the "nasal" subsystem needs to be accessed in
every single Nasal extension function, and multiple "nasal" subsystems are
out of the question, anyway.
we need to explicitly destroy that here, too, so that it has guaranteed
access to the Nasal subsystem. Otherwise we get a segfault on exit. When
the next subsystem needs this special treatement (radar?), we should
introduce a new subsystem group (in addition to INIT and GENERAL)
"FATAL: PUI: No Live Interface! Forgot to call puInit ?"
We shouldn't use the splash progress message before guiInit().
Leave the "idle_state" step for now, to keep the similarity
with fg/plib as big as possible. This can be dropped later.
Patch to enable atc chatter (and any other arbitrary "message" audio file)

played at a hardcoded volume of 1.0)
- loop up file name in the cache at startup. If it's found, check if the
file exists and use it, otherwise scan $FG_ROOT/Aircraft/ as usual,
and create a new cache while doing that. Rebuild cache on FG_ROOT change.
getAttribute("archive") returns 1 if the attribute is set, and 0 otherwise.
Allow to query and to set all properties by not specifying an attribute
string: getAttribute() returns all attributes bit coded in an integer,
and setAttribute(attr) sets all attributes. No assumptions may be made
about the meaning of the bits -- they can be changed in future fgfs releases.
The only valid use is to compare or set attribute numbers obtained in the
same fgfs run. This is meant for allowing full copies of property branches.
Also add getAttribute query strings "children" for the number of children,
and "alias".
- fix breakage due to former commit (AIManager.cxx, r1.72)
- make AI properties available in AIBase
- add <valid> property for animations/nasal scripts

cmdarg().getPath());
</load>
<unload>
...
</unload>
</nasal>
Note, however, that the <unload> block is only called on exit at the moment,
not when the tile is unloaded.
