Previously, a static build would produce three separate files:
QtWebKit.a, libjscore.a and libwebcore.a. These seem to have
dependencies on each other and this caused the build errors on Linux.
This change means that the sources of jscore and webcore are both built
directly into the QtWebKit.a target. libjscore.a and libwebcore.a are no
longer built. It is then possible to create a static binary on Linux.

Debug mode turns off all optimisations. This make PhantomJS considerably
slower.
Instead, we build in 'release' mode, but generate debugging symbols at
the same time.
This may present some problems analysing crashes, if the optimisations
make that difficult. However, in my testing I was able to get useful
debug output even with optimisations enabled. So we should see how we go
- if it becomes a problem we can produce seperate debug binaries with no
optimisations.

When console.error was called, there was a segfault because it was
treated as an uncaught exception, but did not have the correct stack
trace information (I am not sure why, but still...)
Now that we are generating the stackTrace in WebCore::reportException,
the MessageType gets set correctly, so we can use this to differentiate
between uncaught exceptions and other messages.

On reflection, this approach seems like a bad idea and a source of bugs.
I think passing object references between pages seems inherently
problematic, and we are better off just passing data to the onError
handler. If users need the actual object reference, they are able to use
try ... catch within the page.
This change also means that we are no longer breaking backwards
compatibility with the page.onError function signature.
WebCore already has a bunch of plumbing to pass around stacks. This
exists for the inspector/console. However, we need to actually retrieve
the error stack in WebCore::reportException.
To achieve this, I am attaching a stackArray property to the error
object. This is not as clean as I'd like, but seems ok for now. (We
should not document stackArray though.)

Note that for errors that occur within subpages, this object is not the
real error object, but a copy. This is because the real object exists
within the subpage, but the page.onError handler runs within the main
context, so we have to pass it through as data.

ISSUE: 460 (http://code.google.com/p/phantomjs/issues/detail?id=460)
this is a backport from qtbase:

We need to reregister fonts in initializeDb because basic font db
doesn't have an internal record like fontconfig does, so just
repopulating the font database won't work. db->reregisterAppFonts
is now used properly as intended (reregister application fonts
after the system font database has been cleared).
Also, static variable 'initialized' in initializeDb() is removed
since we check privateDb()->count to see if it needs to be populated
again.

Usage:
page.paperSize = {
margin: "1cm",
header: {
height: "1cm",
contents: phantom.callback(function(pageNum, numPages) {
return "<h1>" + pageNum + " / " + numPages + "</h1>";
})
},
footer: {
height: "0.5cm",
contents: phantom.callback(function(pageNum, numPages) {
return "<h2>" + pageNum + " / " + numPages + "</h1>";
})
}
};
Note: The contents can return arbitrary HTML but since we cannot
re-layout the whole website for every page, the header/footers
must have the static height defined in the height property.
Note: The new example printheaderfooter.js shows the usage. It
also shows how one could delegate the above to a JavaScript
function on the loaded website, which allows one to print pages
and let the actually printed page decide how the header/footer
should look like.
Note: The page-counter can be reset by adding the class "phantomjs_reset_pagination"
to HTML block-elements that should reset the counter.
ISSUE: 410 (http://code.google.com/p/phantomjs/issues/detail?id=410)
The hasHandler flag passed to JSC::Debugger::exception only applies to
the current stack frame. It does not indicate if there are exception
handlers in earlier stack frames.
Therefore, we are saving the frame when an exception occurs, but only
reporting the exception if it is still present once the stack has been
fully unwound.

In non-static build, JPEG is built as plugin. We force to have JPEG
support built-in by explicitly change a variable in the configure
script (unfortunately this can't be done via command-line options).

These classes are from the official Qt 4.8.0 platform plugins with some
tweaks:
* By default, use Fontconfig font database.
* No need to save the captured screen on every flush.
* Enlarge the screen to make it more like a typical desktop size.

Compositing depends on Graphics View and/or GL-based texture mapper.
Since we don't plan to support either of them, at least for the near
future, we might as well disable compositing.

This is done via the tools/import-qt.sh script. Note that the script
also removes some unnecesary stuff. In practice, src/qt is not as
big as the plain vanilla Qt source tree.
