Details:

Current Gnash's implementation of `Function.call()` and `Function.apply()`
have an incorrect behavior when user specified `thisObject` argument as
`null` or `undefined`, which it caused the function to be called with `this`
instance set to an empty object
<https://savannah.gnu.org/bugs/?47354#comment2> rather than the `_global`
object.

Patch 1 of 2:
See the attached
`0001_supply-global-instance-fallback-for-function-call-apply.patch`.

This patch makes `Function.call()` and `Function.apply()` supply a reference
to `Global_as` (a.k.a. ActionScript `_global`) as the context of function
call
if the `thisObject` argument of the method is specified as `null`
or `undefined`; fixing bug #47354.

Gnash: 0.8.11dev (patched against git 8b33692 7-Mar-2016)
System: Debian GNU/Linux 7.0 Wheezy i386
