[wpe-webkit] Web Extension Support In WPE

[Michael Catanzaro]

So your hang is when taking the VM lock. It must already be locked. 
You'd need to debug JSC internals to understand why that mutex is 
already locked at the time you try to acquire it. That doesn't sound 
very fun, but it's probably your next step.

I would:

 * Immediately disable whatever local change you have made to WebKit to 
allow use of internal WebKit symbols, like GRefPtr and 
jscContextGetJSContext. This can only lead to disaster. It's difficult 
to prevent WebKit from exporting these symbols for technical reasons, 
but none of these symbols are defined in public headers so your 
application should not be using them. Are you declaring them manually, 
or have you changed WebKit to install internal headers?

 * Understand the difference between the the modern GObject JSC API, 
documented at [1], and the old cross-platform API. JSCContext obsoletes 
JSGlobalContextRef, and you should never have any reason to use the 
later if you are using the former. You want to use only one or the 
other, ideally the newer one.
