Parsing the config file should be completely tested before we can rely
on it and safely extend it. This just adds the first very basic tests.

This reverts commit b8f41ef0.

We had good reasons for parsing the file ourselves. For example to keep
expressions like 7*60*60*24 intact.

This allows to use simple arrays in the config file but have a comma
separated list in the config manager.

Until now, the config manager did read and parse the various PHP config
files itself. This fails for more complex setups like arrays.

I'm not really sure why this was done. This patch replaces the parsing
with a simple include() call. Everything still seems to work.

Saving worked, but did you log out everytime. Now it is checked if the
auth mechanism was actually changed before assuming the login is
invalid.

okay. I can't read. we already had a multiline config. It's the default.
So I reverted my change, except for making use of formText/cleanText for
proper line ending handling and I added made focused textareas a bit
larger.

* code/PHP5 cleanup

* fixes merge messup (code was made up from parts of authad)
* code and PHP5 cleanup

* use proper plugin config
* code/PHP5 cleanup

* makes proper use of plugin config
* adds a few first defaults, but the whole config metadata is still
  missing
* proper PHP5 use and comments

* fixes incorrect $this->adldap calls
* makes use of correct plugin config

This does nothing currently but allows us adding certain things
to the base class later.

we now touch the messages before the actual update happens. this should
lower the chance of more than one update check running at a time.

In the recent refactoring of the HTTPClient, a problem with certain
systems was reintroduced. On these systems a select() call always
waits for a timeout on the first call before working properly on the
second call.

This patch reintroduces the shorter timeouts with usleep rate limiting
again.

Since this bug is not reproducible on other systems it can't be unit
tested unfortunately.

Appending files now works at least for uncompressed tar files. Seeking
in compressed tars is not yet supported.

You can give a path and file contents in an array. However this didn't
work because the file_exist() check was done before checking for an
array
