get away from argument stringlists. instead, use native shell command
lines which support quoting/splitting, environment variable expansion
and redirections with well-understood semantics.

- unify unix and windows paths
- on windows:
  - we don't need to care for trailing backslashes, as we never append
    directly to quoted strings
  - simplify, as this doesn't need to be fast.
    unfortunately, it's impossible to use
      ret.replace(QRegExp(QLatin1String("(\\\\*)$")), QLatin1String("\"\\1"));
    as that matches foo\ twice (once one backslash and once an empty
    string).

again, qregexp was putting our raw string into its cache - this time
hidden behind a qdir::entrylist().

Precompiled headers are a performance feature supported by some
compilers to reduce the (re-)compilation time substantially.
Usage in Qt: http://doc.qt.nokia.com/4.7/qmake-precompiledheaders.html



Due to the usage of precompiled headers Qt without demos/examples/webkit
etc might be compiled even faster than Qt Creator on some systems.
Despite of Qt, Qt Creator consist of mostly quite small subprojects
(plugins and libraries) where the effect would not be so noticeable
but still will be visible.

This patch adds default precompiled headers to any plugin and library
(i.e. by changes in src/qtcreatorplugin.pri and src/qtcreatorlibrary.pri
respectively). Almost the same headers are included to general
precompiled header (src/shared/qtcreator_pch.h) like used in QtCore,
just QPointer/QScopedPointer etc and QDebug are added, it is used almost
in any subproject. Also for plugins some QtGui related headers are added
(src/shared/qtcreator_gui_pch.h).

Default precompiled headers are enabled so:

isEmpty(PRECOMPILED_HEADER):PRECOMPILED_HEADER = $$PWD/shared/header.h

So it is possible to override this variable in any place in the project
file in case if it will be needed.

Such overriding is used for Botan (src/libs/3rdparty/botan) - it is
not a Qt project, just a pure C++. Most usable headers were used to
create special precompiled header for Botan. It is 3rd party component
so also src/libs/3rdparty/precompiled_headers folder was created -
to use for any future 3rd party components' precompiled headers.

To enable a usage of precompiled headers feature in Qt projects
'precompile_header' has to be added to CONFIG. It is done by default
for limited platforms only (e.g. not for Linux now), so to enable it on
any other platform - e.g. special qmake command has to be used:

qmake "CONFIG *= precompile_header" -r ../../qt-creator/

To disable a usage of precompiled headers (on platforms where it is
pre-enabled - otherwise it will be used automatically):

qmake "CONFIG -= precompile_header" -r ../../qt-creator/

To see on which platforms precompiled headers feature is enabled
by default - qt/mkspecs folder has to be checked.

Precompiled headers require an additional space on the disk, it looks
like for Qt Creator full size of the shadow build folder grows up to
2 times (e.g. 1.5 GB to 3 GB).

Test results:

Linux x64, gcc 4.4, T7500, 3 GB RAM: About 22.5 minutes are reduced
to about 14 minutes (almost 80% faster).

Windows x86, vs2008, P8400, 2 GB RAM: About 70 minutes are reduced
to about 20 minutes (amazing 250% faster).

crash messages.

When adding a multiselection of images outside the qrc-path,
the file dialog is created every time, causing great
delays due to DBUS problems. Create a context struct
keeping the dialogs around.

this has only an effect if parsing the previous file failed in a place
with a non-empty stack.

- Changed generator to generate:
- Changed AST::lastToken to return 1 if there is none
- Changed Bind.cpp to set the scope of the block following a control
  statement to extend upto (and not including) the first token after
  the block. So basically, including any whitespace after the control
  statement.

QString::isNull() vs. isEmpty() discrimination is a time bomb ...

the root cause is in the API of parsedProFile(): it discerns
isNull() and isEmpty(), which is of course a time bomb.
but in this case the right solution is not trying to parse
the empty string in the first place.
