libjpeg-turbo: update to 3.0.0

[mohd-akram (Mohamed Akram)]

Maintainer Notes:

• This must be done with extreme caution - and with a great amount of care and pre-testing - as this is a foundational port. (With 340+ dependents, as of 2023-07-16.)

• Upstream's release notes mention that there are some breaking changes, including removal of deprecated APIs. This almost guarantees that some ports - particularly those that are older, and/or no longer maintained by upstream - will break.

Given all of the above, this will take plenty of time before we can update. And ultimately, it's possible that we may have to create a new segregated port - say, libjpeg-turbo-3 - to maintain backward compatibility for those ports that don't work with 3.x.

Mohamed, if you're interested in using v3, that's available via libjpeg-turbo-devel:

$ sudo port -f deactivate libjpeg-turbo
$ sudo port -N install libjpeg-turbo-devel
$ sudo port rev-upgrade

While the ABI appears to be compatible-ish - such that you may not see any issues during rev-upgrade - it's at build time that you'll see failures.

[mascguy (Christopher Nielsen)]

Rather than attempt to build all dependent ports against v3 - which simply isn't practical locally, nor doable via GitHub CI - I'll start digging based on buildbot binaries.

The emphasis will initially be on the TurboJPEG API, as that's where most of the breaking changes were made. Whereas the libjpeg API has remained relatively stable.

In any case, the following recipe was provided courtesy of Ryan, during investigation of poppler dependents. And that's what I'll use, with the caveat that I'll have to build ports whose license preclude binary distribution. (Unless Ryan or Josh are interested in helping check those.)

• Make a list of archives of all ports that depend on libjpeg-turbo, that aren't noarch
• Download all public archives
• Decompress each archive, checking if it contains a reference to libturbojpeg*.dylib

Blocked on #68246.

Everything else either built successfully against the new version, or failed for non-jpeg-related reasons.
