Thomas Jarosch 3c915b534d Match compiler: Collect and cache plain C-strings
Profiler runs with gperftools showed we were spending
a lot of time in strlen() even with compiled match patterns.

If you compare a std::string with a plain C-string,
the comparison operator needs to calculate the length
of the C-string via strlen().

We can avoid this by turning all C-strings into C++ strings,
which cache the string length internally.

The match compiler has been adapted to collect all
C-strings during compilation and aggregate them.

Benchmark on the 'rpm' code base on a Core i7 920 box:

cppcheck without matchcompiler:
real    0m30.977s

cppcheck with previous matchcompiler:
real    0m28.157s

cppcheck with cached C-strings:
real    0m17.823s

Kimmo Varis fe9e6130cf Add general PRO file for console builds.
It is easier to maintain PRO files when we keep all the console-
build specific general options in one file. For example changes to
compiler options affect to all console builds.

This fixes the potential (but not likely to happen) case when
file list is empty. Dan suggested this change when reviewing my
earlier patch.

Kimmo Varis 734d4af007 Tests: Generate test file listing with dmake.
Use dmake to generate a test/testfiles.pri with all the files
containing tests. The testfiles.pri is included by the test/test.pro,
which compiles the test runner. This automates the test file listing
instead of former way to hand-edit the file list.

Fixes ticket #3885 (dmake needs to create a list of test files for qmake)
