Change libvgl's set4pixels() and set2lines() functions from plain

'inline' to 'static inline'.  Otherwise, a C99 compiler (such as clang)
will output an undefined symbol for those functions in the resulting
object file.  (Even gcc will do this, when you use "-std=c99".)

This should fix the "undefined reference to `set4pixels'" errors that
some people were seeing during ports building, when their world was
compiled with clang.
