[Plplot-devel] xwin_common.c folded back into xwin.c

[Maurice L. <mj...@ga...>]

I finished the changes necessary to return the "external API" functions
previously moved to xwin_common.c back to xwin.c.  The driver escape function
is now used to access these, which is much cleaner from a linkage standpoint.

I was able to simplify the PLColor<->XColor interface by using a temporary
stream variable (tmpcolor), so all the extensions were trivial.

I did have to introduce a new call in plframe.c to pllib_initdev() (was
plGetDev) to load the device driver & set up the dispatch table before the
escape function can be called.

Anyhow it is a cleaner design now and everything seems to work fine, except
the install problem that was present before my commits.

Should be no problem to do this same procedure on the tkwin stuff.
