Change license to AGPL
This commit:
- Updates the `LICENSE` file
- Start every file with something like:
// Copyright YEAR_FIRST_PUBLISHED Signal Messenger, LLC
// SPDX-License-Identifier: AGPL-3.0-only
---
First, I removed existing license headers with this Ruby 3.1.2 script:
require 'set'
EXTENSIONS_TO_CHECK = Set['.h', '.hpp', '.cpp', '.m', '.mm', '.pch', '.swift']
same = 0
different = 0
all_files = `git ls-files`.lines.map { |line| line.strip }
all_files.each do |relative_path|
if relative_path == 'Pods'
next
end
unless EXTENSIONS_TO_CHECK.include? File.extname(relative_path)
next
end
path = File.expand_path(relative_path)
contents = File.read(path)
new_contents = contents.sub(/\/\/\n\/\/ Copyright .*\n\/\/\n\n/, '')
if contents == new_contents
same += 1
else
different += 1
end
File.write(path, new_contents)
end
puts "updated #{different} file(s), left #{same} untouched"
I'm sure this script could be improved, but it worked well enough.
Then, I created `Scripts/lint/lint-license-headers` and ran it to auto-
fix a lot of files. This changed the mode of some files, but I think
that's actually desirable. For example,
`SignalServiceKit/src/Util/AppContext.m` previously had a mode of
`0755/-rwxr-xr-x`, and it's now `0644/-rw-r--r--`.
Then I fixed some stragglers and updated the precommit script.

To improve message reliability, we're adding an urgency flag to outgoing
messages. For example, outgoing calls are urgent, but delivery receipts
are not. [Android][] and [Desktop][] have already done this work.
At a high level, I added an `isUrgent` property to `TSOutgoingMessage`s.
It defaults to `true`. Some subclasses, like
`OWSReceiptsForSenderMessage`, override it to return `false`.
Builds off of a few other commits (not necessary to understand this
commit, but might be useful for posterity):

This change should have no direct user impact.
`OWSOutgoingReactionMessage` was untested. This adds a basic test for
its `shouldBeSaved` method.
I think this is a useful change on its own, but may make future changes
easier, too.
