This commit:

- Updates the `LICENSE` file

- Start every file with something like:

      // Copyright YEAR_FIRST_PUBLISHED Signal Messenger, LLC

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.
