newlines are like whitespace, so items don't run together

Task-number: 250574

merge 3570e978058816745101a69b552ad9d07e349542 and
00f2031c60bc472544b509586ee31c643ab2e81d from qt.

Task:     247606
Details:  Remove all the magic which build on top of the cumalative
parser. Instead trust the exact parsing to get those variables correct.
This required a bug fix in the profile evaluator, done with ossi.
Hopefully this doesn't break windows/mac. Will check.

Task:     247606
RevBy:    analysis and bug fix mostly by ossi
Details:  More fixes might be needed.

unlike the conditional variant, the substituting variant may actually
provide interesting output with rather low likelyhood of side effects.
btw, my FIXME was bogus - i confused the two variants.

Details:
"CONFIG = foo bar" resulted in "CONFIG = bar"
"CONFIG = foo
CONFIG = bar $$CONFIG"
resulted in "CONFIG = bar bar"

Task:     - 244263
RevBy:    - dt

Details:  - Happened in release builds when opening pro files with
CONFIG scopes and a non-valid Qt version set.

    RevBy:    dt
    Details:  create QDir objects ony when needed

now we process all includes and loads in cumulative mode again.
functions without side effects don't need special attention in the first
place, obviously. and the printing functions already have their own
handling.

- include all known functions into the map
  - some of them are actually enabled
- constant_names ~= s,CF_,T_,

Task:	229217

without that, the auto-included highly complex files from mkspecs/ make
it spew out oodles of warnings.
by default, the user-provided files are still scanned in "cumulative"
mode (ignoring conditionals), so we collect as many files as possible.
(ported from qt)

code mostly c&p-d from qmake (sync from qt).
