gwbuild: Work on existing classes.

- added some functions to keyvaluepair*.{c,h}
- change type of "includeList" from GWEN_STRINGLIST to GWB_KEYVALUEPAIR_LIST

Correct type mismatch for _threadRun_cb.

Fixes https://www.aquamaniac.de/rdm/issues/230

GWBUILD: Added some more classes.

Started working on gwbuild.

gwbuild is my 2nd try to build a small and fast build system. It will
first be tested with AqDatabase and might later be used with other
projects, if all works out.

Released version 5.5.0stable.

Released 5.5.0stable.

Prepared release 5.5.0stable.

OS: Windows stuff can now be compiled again.

GWEN_DATE: Major speedup.

The function GWEN_Date_fromString() is very often called by Aqfinance
so a speedup here improves the overall performance of AqFinance, too.

Build: Moved header files to installable section.

GWEN_IdList64: Make argument to GWEN_IdList64_Iterator_new() const.

From now on GWEN_IdList64_Iterator_new() will no longer attach to the
original list which makes it possible to change the argument to const.
This also means that the iterator class can be used even in multithreaded...

Added a test for nogui code and multi-threading.

Fixed a bug in nogui.c.

Loghook needs to return "1" for handled messages, otherwise GWEN_GUI
will fallback to printing the log message by itself.

Fixed a makefile target.

Fixed a compiler warning.

Added GWEN_NoGui_new() which returns a GUI implementation which does nothing.

Use this as a template for your own implementation of as a simple
implementation for side-threads.

No longer directly use global variable gwenhywfar_gui.

We now use a thread-local variable, so a thread can set its own GUI
implementation.

The reason is that most X11 GUIs down allow any thread of a process other
than the main thread to access the graphical interface. If a thread function...

Fixed typos.

Started reworking GWEN_GUI.

Split gui.c into multiple files to get an overview.

Added class GWEN_THREADLOCALDATA.

For now only implemented for POSIX systems using pthread.
Started implementation for Windows (not tested, yet).

Added axm_pthread.m4 (copied from aclocal-1.15).

Use AX_PTHREAD instead of ACX_PTHREAD (the latter doesn't seem to exist on my jenkins machine).

Fixed some compiler warnings.

Add PTHREAD_CFLAGS to libgwenhywfar_la_LIBADD.

This adds "-pthread" to CFLAGS, which should have been done by
ACX_PTHREAD (seems to be a known problem).

OS: Added first thread implementation for Windows (not tested, yet).
