Without it, following error occurs on Fedora 15 when compiling for
x86_64:
/usr/bin/ld: npplayer-npw-player.o: undefined reference to symbol
'dlsym@@GLIBC_2.2.5'
/usr/bin/ld: note: 'dlsym@@GLIBC_2.2.5' is defined in DSO
/lib64/libdl.so.2 so try adding it to the linker command line
/lib64/libdl.so.2: could not read symbols: Invalid operation
collect2: ld returned 1 exit status
Fedora already has a patch that adds -ldl to LDFLAGS

In case a plugin attempts to check this (unlikely as no browser
implements it yet) and avoid NULL checks on all the entry points, we
shouldn't crash. Also, for correctness, even if the browser supports it,
a browser + nspluginwrapper combination doesn't.
To say nothing of atomicity, lots of Bad Things happen when you replace
libraries in-place. gdb apparently gets upset at you, and you get random
crashes in programs which have the library loaded. Evidently libdl.so
can't even handle it. It's unspecified whether changes to a file mmapped
as MAP_PRIVATE are visible to the process.
Fixes#35.
Browsers are supposed to set it all the time, if we take what Firefox
and Chrome do as the spec (which is as reasonable as anything). May as
well apply the workaround everywhere instead of assuming only Flash
needs it.

Otherwise the check for attempting to load the wrapper template plug-in
fails in GTK WebKit (which tries to call NP_Initialize on every
plug-in).
Reported by Arch Linux users.
Unfortunately, while Konqueror pretends to have an Xt event loop, it is
completely non-functional. Block hooks will not run, because it is a Qt
event loop polling Xt. Work procs also do not work because Xt does not
report them in XtAppPending. A timeout should, in theory, work, but
Konqueror doesn't even enable its Xt bridge most of the time! If the
plug-in requests XEmbed (as Flash does), a PluginHostXt is never created
and XtEvents::enable is never called. Instead of fighting all this, just
use the glib event loop. They have a bridge and Qt uses the glib event
loop these days anyway.
The only reason it used to work is because, not supporting windowless
plug-ins, most of communication was from browser to plug-in. Requests
would just get queued up and (with luck) not time out. With the new
delayed sync mechanism, we are unable to register the delayed sync and
instead the plug-in hangs.
This file needs to be replaced with something else entirely, but it'd be
good to get rid of some of disturbing buffer-manipulation logic. The
plugin itself depends on it anyway.
Now that recent stable versions of Firefox, Chrome, and Flash all
implement it, we should wrap it.
Tested in Flash 10.3 with Chrome's 'Clear Browsing Data', Firefox's
'Clear Recent History', and Firefox's 'Forget About This Site'. It
appears Flash ignores maxAge and, when asked to clear all data ever,
sometimes gives NPERR_GENERIC_ERROR. But those aren't problems on our
end, and it seems to otherwise work.
See bug #6.
