There is no need for this check, since these files should not have any
main code that is executed on direct call.

Fixes PSR1.Files.SideEffects.FoundWithSymbols

We have to support lots of legacy code without namespaces

because backwards compatibility. There will be more excludes. This is
just a start.

This makes sure all files use line lenghts shorter than 120 characters.

This is a quick fix. It might not always be the nicest change.

First start at declaring visibilites for methods and properties. Still
missing: the parser/renderer stuff and the plugins

They are now proper abstract classes

I also introduced an auto loaded namespace for the tests.

I made a lot of things public that probaly should be protected. But many
syntax plugins do access renderer mechanisms directly, so better stay on
the safe side here.

The base renderer is now abstract.

This moves all the parser classes into their own namespace and files.
Next up are the handler classes.

I'm not sure about the namespace, yet. A nested namepspace Parser\Modes
would probably make more sense... we'll see.

This also removes the duplicated coded in the Plugin mode. We now use
the plugin trait and can inherit from AbstractMode instead.

Used the wrong quotes to split up the string. But actually, we can just
use a linebreak. Doesn't matter for HTML.

For now I left Doku_Handler itself as it were. We will need to keep the
class name around for backwards compatibility but should move the class
itself.

I introduced a new ReWriter Interface to formalize how the various call
writer implementations are accessed.

There are a whole bunch of doc blocks missing.

* master:
  typo
  link to avanced geshi options. fixes #2352
  unlock in cancel action
  unlock pages on viewing them
  add user interface back to resendpwd action. fixes #2349

All properties are declared protected. The handler is now set via the
constructor.

This should better adhere to SRP and simplify things.

This class has been replaced by the classes in the
dokuwiki/Subscriptions namespace.

Refactor subscriptions

* psr2-pluginredux:
  Minor optimizations in PluginController
  Snake to Camel case fixes inn PluginController
  Fix snake->camel case, doc blocks
  minor code simplification
  snake to camel case fixes in EventHandler
  Move list of plugin types to plugin controller constant
  Avoid accessing the evet system before it's intialized
  Avoid processing events before the Event System is intiialized
  isEnabled instead of isDisabled
  removed get_directory() method from PluginController
  fix type hints
  moved plugin controller to Extension namespace
  removed deleted file from autoloader
  deprecated trigger_event() in favor of a static method on Event
  First go at moving the plugin classes into their own namespace

We still need to ignore a bunch of stuff for backwardscompatibility

Subscriptions are autoloaded now

We define and register the autoloader here.

These will be loaded via include, later on and should be cachable by
Op-Cache.

The formatting has been adjusted to have one entry per line to make
diffing much easier in the future.

For now duplicate keys and commented code from the originals have been
kept. But this should probably be cleaned up in the future.

For now these tables are not used, yet.

This doesn't really change much since the old functions are still needed
for compatibility reasons. We may be able to reduce the number of
functions by checking which ones we really need.

Docblocks, imports, etc...

mostly overlong lines and more exclude patterns

Actually replacing all calls is still to come.

also avoids overlong line

For now this uses full qualified namespaces, sensible imports may come
later.

This class needs to be replaced with dokuwiki\Form in the future.

* utf8refactor:
  replaced deprecated utf8 functions
  formatting cleanup
  mark old utf8 functions deprecated
  Some cleanup for the UTF-8 stuff
  Moved all utf8 methods to their own namespaced classes
  Create separate table files for UTF-8 handling

We replace original PHP methods here and the original method is in
snake_case, so it makes sense to keep it this way even though that
violates PSR-2

changes from commit b15f23f may have
been lost, because the code changed to much.

changes from commit df81ca9 need to be
verified. we might need to do some more adjustments.
