This changeset makes it possible to build the Second Life viewer using
Python 3. It is designed to be used with an equivalent Autobuild branch
so that a developer can compile without needing Python 2 on their
machine.

Breaking change: Python 2 support ending

Rather than supporting two versions of Python, including one that was
discontinued at the beginning of the year, this branch focuses on
pouring future effort into Python 3 only. As a result, scripts do not
need to be backwards compatible. This means that build environments,
be they on personal computers and on build agents, need to have a
compatible interpreter.

Notes

- SLVersionChecker will still use Python 2 on macOS
- Fixed the message template url used by template_verifier.py

SL-16124 First pass at a Python3 script to launch multiple non-interactive Viewers with differing command line options

SL-13705 - added --deleted option to collect info on no-longer-needed text in translated files. Processing needs to be automated as the list is unfeasibly long.

SL-13705 - language list defaults to the standard supported set of FR, ES, IT, PT, JA, DE. '--lang all' will also use this list

SL-13705 - lock all columns except C in the excel file (apparently google sheets does not respect this setting on import)

SL-10238: Viewer spport for push notifications from the simulator contaiting partial groups of settings.  Blend these settings into the current environment.

SL-10093: Client code to support experiences changing an environment.  Handle generic messages with "commands" to be executed.

Remove compilation and linkage of deferredUtil and indirect GLSL helper objects (current source of Intel ig4icd driver crash).

SL-966 - animated object size/pos constraints cont, including some settings for debugging. additional options to anim_tool.py for making test animations

MAINT-7699: More robust cap protocol, better support for delete and support for individual tracks, support for setting environment by asset id in the cap
MAINT-7703: Initial flags sent in message protocol for parcels

The nghttp2 autobuild package has copyright information that embeds a newline.
autobuild install --copyrights correctly produces that information onto two
lines. But that means packages-formatter.py must process any lines that do not
match its expected 'packagename: copyright' pattern as the continuation of the
preceding package's copyright information.

Since the processing for autobuild install --versions is so very similar, fold
both into the same outer loop.

Also report all duplicates for any package, instead of stopping at the first.
