[!!!][TASK] Rewrite install tool

• The god class "Installer" is gone and split into two major parts.
  A step controller handling major upgrade and install tasks, and a
  tool controller handling the known install tool actions.

• The step controller is designed to be always called prior to the
  tool controller, if a step needs execution, it comes up, otherwise
  the tool controller will be executed.

• The entry point typo3/install/index.php is gone and substituted
  by typo3/sysext/install/Start/Install.php. The file contains a
  lengthy comment to document the main request flow and used GET/POST
  parameters.

• Most parts of the install tool do not bootstrap the whole system
  anymore, in general only the base bootstrap, dbal (if loaded),
  extbase and fluid ext_localconf.php are loaded. This makes sure
  the install tool can not fatal if some extensions ext_localconf
  is broken. The whole install tool runs without any caching, so a fatal
  in some cache file can not kill the install tool execution.

• Installing TYPO3 CMS on a dbal enabled system is now handled in
  the step installer directly to make the according code easier to
  understand.

• Rendering is done with a simplified fluid standalone view.

• All install tool forms are CSRF protected.

• A new and fully unit tested class structure is introduced, designed
  to take care of the basic file and folder structure of the instance.
  It is used during installation to create the needed structure and
  can be called in the install tool to compare and fix the current
  instance structure with the expected structure. In effect, the
  "dummy" package is obsolete. An instance can be created by just
  linking index.php, typo3_src/ and typo3/ within the document root,
  the installer takes care of creating everything else.

• The installation procedure is released from the package handling.
  Packages will be handled by the extension manager after initial
  installation with another patch.

• The whole package handling needs to be implemented in the
  extension manager.

• Not all upgrade wizards work, this code area needs some love.

• A 'core' auto updater could be implemented now. A GSoC project
  is currently running to realize this.

• The SQL schema migration API is a mess and should be refactored.
  For now, another helper class is introduced to encapsulate some
  of the nasty details.

• An auto configuration and configuration suggestion system is
  planned and needs to be done. It should suggest best configuration
  options in the install tool, and should auto configure the system
  during installation in the last install step.

• If the backend or frontend fatals due to some extension that
  triggers a fatal in ext_localconf or ext_tables (for example
  due to a require() of a no longer existing file), a small helper
  action in the install tool could find those extensions and suggest
  to unload them.

[TASK] Install tool: Code optimization in update wizard action

An if with only a 'throw Exception' call in it breaks code execution
and acts as a guard clause. The code below does not need to be in
an else case.

[BUGFIX] Install tool: Warning in upgrade wizard

The 'silent' cache framework table upgrade throws a warning that
explode() expects a string but an array is given in
SqlSchemaMigration getStatementArray(). The upgrade wizard uses
a wrong API call, since this method is already called within
getExpectedDatabaseSchema() of the helper class.

[FEATURE] Install tool: Remove obsolete keys from LocalConfiguration

Some configuration settings are obsolete, but they have never been
actively removed from LocalConfiguration. The patch introduces a
list of obsolete configuration options (like SYS/extCache) to the
install tool step controller and silently removes those settings
from LocalConfiguration to keep it clean. This also obsoletes
some deprecation code within core bootstrap.

[BUGFIX] Support mysql socket connection

With the switch to mysqli in 6.1, the connection to mysql server via
socket broke.

• If hostname is "localhost", a socket is used and the socket file
  can be given optionally if it is different from the default.
• If hostname is not "localhost" but an IP address, a port can be
  given that may be different from the default mysql 3306.

The patch now reflects this in the database connect step and adds a
parameter for the optional socket location. The patch will be adapted
for 6.1 to include only the additional optional socket parameter.
