Install dtrace.h and dependencies
This makes the minimum amount of changes to allow inclusion of dtrace.h
without all the solaris compatibility headers. Installing dtrace.h allows
compiling consumers of libdtrace (e.g. https://github.com/tmetsch/python-dtrace)
without requiring a copy of the source tree.
For python-dtrace I worked around this in https://github.com/tmetsch/python-dtrace/commit/58019c9a12022203a9ffda286dd8b41f1a5ace42
but being able to build the library without installed sources would be
extremely useful.
Support for NS_MOREFRAG is broken, as NS_MOREFRAG is copied from
the TX slot to the RX slot rather than the other way around.
Also, the NS_MOREFRAG must be copied also in case of packet
copy (no zerocopy).

loader: instead of hw.vga.textmode, use screen.textmode
hw.vga.textmode is directing VT VGA backend to use text mode.
The default screen mode for BIOS loader is text, and default
screen mode for VT VGA backend is graphics (unless we are running on
hypervisor or hw.vga.textmode is set to 1). Using hw.vga.textmode
for loader does remove possibility to have graphical mode VT VGA with
text mode loader.
screen.textmode can have possible values "0" to disable text mode,
and "1" to set text mode.

ncurses: only keep the version with widechar support
Only keep the widechar version of ncurses as libncursesw.so.9
Keep the old name to avoid breaking the ABI compatibility (the non
widechar version libncurses.so.9 is not binary compatible with
libncursesw.so.9) since all ports and base are already only linking
against the widechar version we can simply remove libncurses.so.9

release, it is simply removed and not added to any binary compat
package.
