donate-cpu-server.py: Replace syntax that is deprecated in Python 3. (#1712)
The function `iteritems()` of `dict`s is deprecated. The recommended
alternative is to use `items()`, this function also works with Python 2.

The next issue is that lambdas can no longer unpack tuple parameters
in Python 3. It would be possible to use some workaround and still use
a lambda, but using `operator.itemgetter(1)` instead is faster and the
recommended method in such a case.

The syntax is now compatible with Python 2 and 3 but the server script
still does not work with Python 3. For example `socket.recv()` returns
`bytes` in Python 3 and `str` in Python 2. Currently `str` is expected
so it does not work with Python 3.

Cppcheck developer and build tools

* tools/matchcompiler.py

The matchcompiler.py is a build script that performs a few code transformations to .cpp files under the lib directory. These transformations are related to the use of Token::Match() function and are intended to improve code performance. The transformed files are saved on the build directory. This tool is silently used when building the code with SRCDIR=build, that is:

$ cd path/to/cppcheck
$ make SRCDIR=build

Here is a simple example of the matchcompiler.py optimization. Suppose there is a file example.cpp under lib/:

// lib/example.cpp
void f1() {
    Token::Match(tok, "abc");
}

void f2() {
    const char *abc = "abc";
    Token::Match(tok, abc);
}

If you manually run matchcompiler.py from the main directory:

$ cd path/to/cppcheck
$ python tools/matchcompiler.py

A file example.cpp will be generated on the build directory:

// build/example.cpp
#include "token.h"
#include "errorlogger.h"
#include <string>
#include <cstring>
static const std::string matchStr1("abc");
// pattern: abc
static bool match1(const Token* tok) {
    if (!tok || !(tok->str()==matchStr1)/* abc */)
        return false;
    return true;
}
void f1() {
    match1(tok);
}

void f2() {
    const char *abc = "abc";
    Token::Match(tok, abc);
}

From this we can see that the usage of Token::Match() in f1() has been optimized, whereas the one in f2() couldn't be optimized (the string wasn't inline on the Token::Match() call). The developer doesn't need to use this tool during development but should be aware of these optimizations. Building with this optimization, cppcheck can get a boost of 2x of speed-up.

* tools/dmake.cpp

Automatically generates the main Makefile for Cppcheck (the main Makefile should not be modified manually). To build and run the dmake tool execute:

$ cd path/to/cppcheck
$ make dmake
$ ./dmake

* tools/reduce.cpp

Cppcheck tool that reduces code for a hang/false positive. To build the tool run:

$ cd path/to/cppcheck
$ make reduce

* tools/times.sh

Script to generate a times.log file that contains timing information of the last 20 revisions.
