This fix makes it so bookmarks work with the tip of the branch as of 11/01/00.
This fix removes the necessity to modify xpcom/base/nsDebug.cpp to
remove the thread safety assertions.
This fix primarily does two things:
1. Make nsActionEvents for all bookmarks/rdf actions
2. Remove the synchronized(this.browserControlCanvas.getTreeLock()) call
around nativeProcessEvents() in NativeEventThread.run().

September 2000. It will run, but without bookmarks.
The changes consist of the following kinds of changes:
Changes to method signatures for methods implemented by webclient.
Changes to string functions.
Changes to account for the demise of PROGIDS in favor of ContractIDs

* Louis-Philippe Gagnon <louisphilippe@macadamian.com>
It enables webclient to be built and run under JDK1.1.x. Note that JavaDOM
does not work under jdk1.1.x.
The fix consists of two elements:
On the Java side, replace all JDK1.2 specific calls with JDK1.1.x
equivalents. On the native side use pre-processer macro for
JNI_VERSION, like this:
#ifdef JNI_VERSION_1_2
#ifndef JNI_VERSION
#define JNI_VERSION JNI_VERSION_1_2
#endif
#else
#ifndef JNI_VERSION_1_1
#define JNI_VERSION_1_1 0x00010001
#endif
#ifndef JNI_VERSION
#define JNI_VERSION JNI_VERSION_1_1
#endif
#endif // END: JNI_VERSION_1_2

listener.
* How to create a new listener type on the native side: <P>
* 1. add an entry in the gSupportedListenerInterfaces array defined in
* ns_util.cpp <P>
* 2. add a corresponding entry in the LISTENER_CLASSES enum in
* ns_util.h <P>
* 3. add a jstring to the string constant list in

* 4. Initialize this jstring constant in CBrowserContainer.cpp
* initStringConstants() <P>
* 5. add an entry to the switch statement in NativeEventThread.cpp

You have to clobber_all in webclient after this change.

Added class WCEventListenerWrapper:

* multiple Webclient event listener types. <P>
* This is simply a "struct" type class that encapsulates a listener

* @see org.mozilla.webclient.wrapper_native.NativeEventThread#addListener
Made it so when a java listener is added,
* We create a WCEventListenerWrapper containing the user passed
* DocumentLoadListener, and the string obtained from
* DocumentLoadListener.class.getName();
We then call nativeEventThread.addListener:
* Takes the abstract WebclientEventListener instance and adds it to a
* Vector of listeners to be added. This vector is scanned each time
* around the event loop in run(). <P>
* The vector is a vector of WCEventListenerWrapper instances. In run()
* these are unpacked and sent to nativeAddListener like this:

This change creates a new directory, java/webclient/src_share, that
contains the code that will be used in both src_moz and src_ie, and any
other native browser wrapping implementations.
Here are the steps I followed to implement this change.
1. Create a new directory java/webclient/src_share
2. Move all jni_util*.* files from src_moz into src_share
3. Make it so src_share compiles into a new .lib
src_share has no netscape dependencies. Any functionality that
depended on ns dependencies was kept in src_moz. In this case, we
have a function prototype only in src_share, with the implementation
in src_moz. We did this for nsHashtable. The other trick was for
things in WebShellInitContext that had nothing to do with Netscape.
This case was accomodated by creating a new struct, ShareInitContext,
that contains all WebShellInitContext members that have nothing to do
with Netscape. Currently this is just jobject propertiesClass. I
modified the WebShellInitContext struct to contain a ShareContext
struct as its last member. There are two new methods in jni_util.h
that allow for the initialization and deallocation of the members of
the ShareContext struct.
4. Make it so src_moz uses the new .lib to provide the jni_util behavior
a. Create ns_util* files that include ../src_share/jni_util* files
appropriately.
The only tricky part was for things in jni_util.h that

This checkin makes it so CBrowserContainer is properly released. The
problem was that the CBrowserContainer was still registered to the
docShell as a listener. The solution was to call
wcIBrowserContianer::RemoveAllListeners() in the WebShellInitContext
deallocator.

This checkin mainly does two things:
1. Correctly populates the java.awt.event.MouseEvent subclass with the
correct modifiers, x, y, and clickCount for the mozilla mouse event.
2. Adds a performance optimization: previously, every mouse event was
causing a new instance of java.util.Properties to be created. Now,
only one Properties instance is created per-page, and it is cleared on
each mouse event.
Also, I made the DOMMouseListenerImpl constructor initialize the
refCount to 0. This allows the object to be correctly deleted.

Made the constants final so they can be used in a
switch statement
File: EMWindow.java Status: Locally Modified
Modified eventDispatched() so it doesn't call any webclient
events. This was causing the hang. Took advantage of
the newly implemented ability to pass a string from the
mozilla event handler into java.

Native code changes: This fix eradicates all
occurrences of the following symbols
nsComponentManager nsServiceManeger
And replaces them with their nsI counterparts.
The following ns* classes still are used in
webclient, and no plans exist to replace them
with nsI counterparts: nsresult nsCOMPtr
nsCRT nsnull * nsServiceManager occurrences
were replaced with do_GetService(), using a
PROGID. * nsComponentManager occurrences were replaced with a call on the global class gComponentManager, declared in the new file ns_globals.h, and defined in WrapperFactoryImpl.cpp. ns_globals.h is included in jni_util.h. See the attachment to bug 33099 for ns_globals.h * Added deallocation code to WindowControlImpl.cpp nativeTerminate. I know it doesn't do much, but it's correct. Java code changes: * Added static method BrowserControlFactory.appTerminate(). This method simply calls the existing BrowserControlImpl.appTerminate(), which calls WrapperFactoryImpl.cpp nativeTerminate(). BrowserControlFactory.appTerminate() is called from EmbeddedMozilla's WindowListener, which gets fired when the user signals she wants the app to terminate.
