The problem was that for

Foo::Foo
(|)

when the user triggers completion at |, startOfLine() returns a token
that's not on the current line and not yet tokenized by that instance
of the BackwardScanner.

As a fix I explicitly ask the instance to tokenize up to the given
index.

Introduce multithread-locking to Core::MimeDatabase as it is
invoked from the indexer thread to sort apart headers and sources.
Add a convenience to operate on a sequence to avoid locking for each
file.

This reverts commit 2a59d2ae.

Because apparently, while designing the Objective-C language, somebody
thought it was a world-class idea to allow any white-space between the
'@' character and the subsequent keyword. With this fix, we now
correctly parse:
    @  dynamic
and:
    @
      selector
and:
    @"foo"
     "bar"
    @"mooze"
(This last one is 1 single string split over multiple lines.)
Wonderful, isn't it?

What we (and Clang) do not support, but what GCC supports is something
like:
   @"foo"@@  "bar"  @"mooze"  @@
which is equivalent to @"foobarmooze".

QMake passes those headers directly to gcc, so the user doesn't need to
include themselves.

They were no longer showing e.g. the file name of the diffed file.
Also separate editor id and editor context a bit.

  * Use id() for methods returning a string used to represent
    some type of object.
  * Use displayName() for strings that are meant to be user
    visible.
  * Quieten some warnings while touching the files anyway.
  * Move Factories to their products in the plugins where that
    was not done before.

Avoids some annoyance for people using case-sensitive completion, when
unrelated completions items would get higher relevance because they
start with the typed string when matched case-insensitively.

In case-insensitive mode, a case-sensitive prefix match now does get a
higher relevance than a case-insensitive match.
