generalise the linker flags used to export symbols by setting them on
a per-OS basis.

all dependencies on packages depending on "png" which contain shared
libraries, all for the (imminent) update to the "png" package.

Fixes to several problems that quickly arose with 4.1.2
---------------------------------------------------
- Dependencies of source files on built sources caused build to stop.
It would continue correctly after restarting, but by making the objects
dependent instead we made it work in one pass.
- References in _regstream.c. Missing references/deletes in _regstream.c
and steamline.c caused objects to be really deleted before their time.
Problem appeared in ThunderStreamlines example. Did this ever work?
- Not enough memory allocated for buffer in parse.c.
- Needed to pass in class_srcdir value to invokation of class script
in libdx/local.mk
- Include net2c in distribution
- Correctly free search_for in Browser.C. Proper behavior dependent on
compile-time definitions.
- Not enoucgh memory allocated for type-in string in GARApplication.C.
Caused segfaults in prompter.
redefines about which buildlink.mk files would care is BUILDLINK_X11_DIR,
which points to the location of the X11R6 hierarchy used during building.
If x11.buildlink.mk isn't included, then BUILDLINK_X11_DIR defaults to
${X11BASE} (set in bsd.pkg.mk), so its value is always safe to use. Remove
the ifdefs surrounding the use of BUILDLINK_X11_DIR in tk/buildlink.mk and
revert changes to move x11.buildlink.mk before the other buildlink.mk files.
use X11_BUILDLINK_MK as a test value. Generally just reordering the
inclusions so that x11.buildlink.mk comes before the other buildlink.mk
files will make everthing work.
--without-javadx to configure script to prevent java programs from being
detectedly inadvertently (hidden dependency). Also add dependencies on
several other graphics and math packages to make DX more useful as a
visual data explorer and capable of reading more diverse data files.
