Andrew Osmond 620833163a Bug 1852144 - Disable remote canvas globally in case of unrecoverable error. r=gfx-reviewers,lsalzman
This patch makes the remote canvas enabled state global. If we failed to
create a context, then it cannot recover, so we should never try again.
In the event of stream errors, it is likely due to virtual memory
shortages.
