NetBSD Status

[Landon Fuller]

Howdy All --

Dalibor has asked me to elaborate on the status of NetBSD support.

When we brought over the BSD changes, we had to remove a small amount  
of code for which a Sun Contributor Agreement was not available --  
this included the NetBSD-specific changes.
This patchset is relatively small, and should be a small project to re- 
implement by someone interested in NetBSD support.

Here is a list of the NetBSD-specific work that was removed, based on  
the commit log messages:

	- jdk/src/solaris/native/java/net/
		NetworkInterface.c:
			Added missing includes for ETHER_ADDR_LEN, etc

		bsd_close.c:
			Explicitly initialize file descriptor table mutexes (should be done  
on all platforms, not just NetBSD)

	- jdk/src/solaris/native/java/io
		UnixFileSystem_md.c:
			Use statvfs on NetBSD, instead of statfs

	- jdk/src/solaris/javavm/include
		typedefs_md.h:
			Include stdint.h for intptr_t on NetBSD

	- hotspot/src/os/bsd/vm
		os_bsd.cpp:
			Stub out NetBSD thread priority functions

	- hotspot/src/os_cpu/bsd_x86/vm
		threadLS_bsd_x86.hpp:
			Define PAGE_SHIFT for NetBSD

		os_bsd_x86.cpp:
			NetBSD does not have pthread_np.h
			Fix context_trapno define, works on current NetBSD/i386


Here are the Makefile changes:
	- jdk/make/common
		Defs.gmk:
			Define LDLIBS_COMMON for NetBSD

		Defs-bsd.gmk
			Use -rpath /usr/pkg/lib for NetBSD

	- jdk/make/common/shared/
		Defs-utils.gmk:
			Use echo -e to expand "\n", etc

	- jdk/make/common/shared
		Platform.gmk:
			Use awk instead of cut/expr to be NetBSD friendly

Additionally, these makefiles were updated to search for libiconv in / 
usr/pkg/lib:
	* jdk/make/java/instrument/Makefile
	* jdk/make/java/npt
	* jdk/make/sun/splashscreen
