It's true that, in general, the timeline is fairly immutable and the Doctor's actions tend to just lead to what has already happened. It's also been demonstarted that it can be changed. I don't think it's right to just ignore all of those other occurrences!
In any case, this was explicitly made out to be a special case.
They repeatedly emphasised that his death had already happened, that it couldn't be changed except by a force outside the Universe. Then they showed a force outside the Universe changing it. The only conclusion is that the timeline was changed. It would just be perverse to interpret those events any other way, IMO.

“So my "head canon" or theory is that the Clara splinters always existed and have always been there, helping Doctor's 1 through 10 from behind the scenes at critical moments, even though we didn't see her in 1963 - 2012 and the Doctor was unaware till part way through 11's tenure.”
i can't i magine that only two out of the millions of Clara splinters ever showed themselves to the Doctor. It doesn't seem very credible.
Also, if that's how things work, why would the GI think he could change things if the existence of the universe in it's current state implies he failed? Why would things start to fall apart when the GI jumped in and then reset themselves when Clara followed? The show was clearly demonstrating that these splinters had the power to change the timeline.

“Which leaves the issue of the Doctor's death at Trenzalore and his timeline persisting there. At some point in the Doctor's distant future he does die on Trenzalore. I don't recall anything which confirmed it was 11 who died there”
There was the TARDIS tomb with the cracked window which matched the crack it acquired after its crash-landing on Trenzalore. It doesn't have that crack now.
There was the fact that the TARDIS control room was set in the 11th's configuration.
There was the whole business with Clara returning from being spread across his timeline and explicilty stating that she had seen no other Doctors besides the ones we know about. Now, admittedly, we saw that it's possible to miss a doctor as she never saw the War Doctor but to miss every future Doctor beyond the 11th? That sequence was clearly designed to show that there were no other Doctors.
Besides, it would be a hell of a coincidence to be buried on the same backwater planet that he almost died in the first time.
My own theory is a bit convoluted but, for the Grave we saw on Trenzalore to be some indeterminate future Grave where he died on Trenzalore anyway, with the TARDIS reset to the same Console room that he had when he first landed there and with the TARDIS window cracked in exactly the same way that it was cracked the first time it landed there. It just seems way too big a stretch!
