PSR-12 compliancy

Migrate all the logging handlers to namespaces. Make SimpleSAML\Logger a bit more intelligent so that it allows using custom logging handlers. Now you just need to implement SimpleSAML\Logger\LogginghandlerInterface in a class, and set the 'logging.handler' option in the configuration file to a string with the full name of your class.

Fix build. If we are logging to STDERR, we don't have to write to the filesystem anyway, so why checking?

(being respectful with occurences that might change the behaviour, i.e. default database prefixes)

Move SimpleSAML_Utilities::initTimezone() to SimpleSAML\Utils\Time::initTimezone(). Deprecate the former.

Refactor SimpleSAML_Utilities::isWindowsOS() to SimpleSAML_Utilities::getOS(). Reimplemented to support most operating systems.

Schedule SimpleSAML_Utilities::isWindowsOS() for removal.

Reformat the logging classes. Extract the LoggingHandler to its own file. Add proper documentation. Fix typos.

Add SimpleSAML_Utilities::isWindowsOS and chmod file in SimpleSAML_Utilities::writeFile() (issue #469).

PHP on Windows does not differentiate between all the different log
levels, which means that attempting to specify the 'logging.level'
option will not work properly. This patch replaces the use of the
syslog constants with custom constants.

Thanks to Ryan Panning for fixing this bug!

Added options to configure processname for logging. Usefull when having multiple installations on the same machine.

Processname in the log is determined by the 'logging.processname' configuration key. It defaults to "simpleSAMLphp" if not set.

Adding a SIMPLESAML_INCPREFIX parameter before the inclusion of new files. This workaround was neccessary for university of oslo to make simplesamlphp work when ini_Set was not available.
