To do that, switch from the deprecated signal() to sigaction().
Instead of reinstalling the signal handler, only use SA_RESETHAND for the
signals generated by a bug.
Also stop interfering with the coredump functionality of SIGQUIT, but
handle SIGHUP like SIGTERM and SIGINT.
As discussed in http://forum.openclonk.org/topic_show.pl?tid=2917, I
have merged all copyright notices into a single file and referenced that
merged file from each source file.
For the updated source files, the timeline has been split into three
parts:
1. Pre-RWD code (before 2001)
2. RWD code (2001 through 2009)
3. OpenClonk code (2009 and later)
All pre-RWD copyright notices have been left intact, as have RWD-era
copyright notices where the file did not have a RedWolf design copyright
notice but only individual author ones. All copyright notices of the
OpenClonk era have been replaced by a single notice ranging from the
first recorded year to the current year (2013). Mape code did not get a
OpenClonk Team copyright notice because it is somewhat separate from the
main OpenClonk codebase and has only been touched by Armin Burgmeier.
Technically this mark is incorrect; we do not handle things differently
on high DPI settings. On the other hand, marking OC DPI aware means that
Windows won't try to scale our drawing, clipping menus and rendering in
the process.
Somewhere in the future, OpenClonk should also add proper DPI awareness
and change the default zoom and menu scaling to match.
