Andrew Osmond 2cb9576c72 Bug 1709303 - Part 1. Prepare scripts and patches for libjpeg-turbo update. r=jrmuizel,tnikkel
media/libjpeg/1050342.diff is no longer necessary and a correction
appears to have been made in the library. Chromium no longer uses this
patch either.

media/libjpeg/assembly-tables.diff and media/libjpeg/externalize-table.diff
require significant changes in order to apply. This may be done in a
future followup patch, but is deemed less important than updating
libjpeg-turbo.

With these patches, an update to libjpeg-turbo 2.1.1 should apply
cleanly and build.
