ASDL supports NetBSD and OpenBSD now

Start revision 371 on the SVN, ASDL begins to support NetBSD and OpenBSD.
Now, ASDL Support Windows 2000/XP/2003/Vista, Linux, FreeBSD, NetBSD, OpenBSD, and other POSIX compatible OSes.

NOTICE:
<OpenBSD only>
During making (compiling or linking) ASDL on OpenBSD OS, few security warning will be shown and tell you to use the strlcpy function to instead of strcpy function. But there isn't function strlcpy beyond BSD OSes, and I have made necessary security ckecking to prevent buffer overflow. So, I decide to ignore the warning currently for the compatibility on source codes level with other POSIX compatible OSes.

BTW, because the changes are few, so I don't intend to release the version in solely. The next release is version 1.5.0 in the plan. So, the new features are only available on SVN at present.
