the cumulative mode tries hard to never lose already assigned variable
values. the naive implementation turned assignments into additions,
which made the trivial construct "FOO = $$FOO" double the size of the
array each time it would be executed.
so instead let the assignments be assignments, and then re-add the
values that would be dropped.

raw strings would break things due to the missing null terminator. this
did not affect unix, as there we convert to 8 bit anyway.

Task-number: QTCREATORBUG-1364

use local8bit instead of latin1 resp. 8bit-passthrough, after all.

the situation was as follows:
- if the pro files and file names were all ascii, everything just worked
- if either contained non-ascii:
  - on unix, the evaluator would work as long as the file content
    encoding matched the file name encoding, and the ui would work as
    long as the file name encoding was latin1 (i.e., on no modern
    system)
  - on windows, both would work only if the ansi code page was
    latin1/cp1252 (i.e., on western systems)

i.e., even in the low-level evaluator, only native latin1 systems with
actual latin1 files worked consistently. given this situation, it makes
little sense to make an encoding adapter between the evaluator and the
ui as originally planned. instead, take the easy way out and use
local8bit - this continues to work for native latin1 systems+files in
the backend, and makes the ui work for everything the backend groks and
some more.

this fixes the recent appearance of qt_webkit_version.pri in all qt 4.7
based projects.

in fact, the patch does somewhat more: it makes the evaluator provide
the information to the higher layers which is necessary for a truly
hierarchical display of includes. TBD later.

the async re-parsing code breaks the assumption that project
parsing only ever starts with a single non-concurrent evaluation
(of the top-level project file), so the population of the base
values in the shared ProFileOption was happily causing crashes.

When dragging the mouse to select an item that is not currently visible,
the ResourceView was not making the selected item visible. This was due
to an unnecessary reimplementation the protected currentChanged slot.

unlike in qmake, the arguments are already expanded at this point
(which is strictly speaking a bug for the iterator variable name),
so it is plain wrong to call doVariableReplace on them.

amazingly enough, qlist::{first,last}() have non-const versions,
which are of course used when you least expect it ...

the sub-strings "escaped" from the evaluator through the accessor, so
things did go boom, after all.
