This reverts commit 1e186c5b.
The code is not symbian specific, linking error was fixed properly
by adding the needed files to HEADERS.

new header files gdbprocessbase needs to be listed in HEADERS

- Saving to file only takes modified data into account.
- Search functionality does not exhaust memory anymore.
- Searches can be canceled. This required updating the IFindSupport
  interface and all classes implementing it. No functional changes
  were done in those.

actual whitespace when the indentation column changes.

Complete whitespace cleanup can still be done either automatically
on save (when configured) or when explicitely called with the
"Clean Whitespace" action from Edit/Advanced.

- when doing backspace, preserve the previous indentation litterally
- when having auto-indentation turned off, simply repeat the previous
  indentation litterally instead of jumping to 0

That's the first step to make the gdb/trk Adapter work with the otherwise
unmodified gdb engine. GdbProcessBase is inherited by GdbProcess and the
gdb/trk Adapter. In the GdbProcess case it's just a wrapper around a QProcess
running gdb, in the Adapter case it's the interface to the gdb process in the
whole rfomm/gdb/gdbserver combo.

evaluating a file (which might not exist) is a bit different than just
merging a (possibly empty) map ...

Fixes a bug where the cmake plugin wasn't finding make, if the make
commands directory was added to path in the build environment.

For implementing mouse navigation in the QML editor.

void main()
{

}
int i;
}

Rationale: The concept of a "Qt Dir" is dead ever since Qt can be
installed. Specifying the qmake location otoh makes it possible to
unambigously detect all parts of a Qt installation.

Also makes the code a lot smaller.

If there are multiple files with the same name, then we try harder to
find the correct one. That is for jom and nmake we have a relative path
so we try to find a file which matches the relative path completly.
Instead of just comparing the last part.
