Add a `--classmap-authoritative (-a)` argument to `composer install`,
`composer update` and `composer dumpautoload`. This enables the same
authoritative classmap behavior as the existing `classmap-authoritative`
configuration setting. The option can be used for creating highly
optimized production autoloaders via `composer install --no-dev
--optimize-autoloader --classmap-authoritative` for projects where
multiple autoloaders are present and unnecessary `file_exists` calls
introduce performance issues.
Closes#4361
Add a "classmap-authoritative" configuration setting that can be used to
disable searching the various prefix and fallback directories for
classes that have not been registered with the
Composer\Autoload\ClassLoader class map. This setting can be used to
optimize performance by avoiding a potentially large number of
`file_exists` calls when Composer is being used in a program with
additional autoloader facilities. Use of the setting implies
"optimize-autoloader" to ensure that the most complete class map
possible is generated.
