Fix many buffer overflows, caused by unchecked string operations
and arbitrary access to arrays. git-svn-id: svn://tug.org/texlive/trunk@4523 c570f23f-e606-0410-a88d-b1316a301751

+ * dvi2xx.c: Fixed a whole bunch of buffer overflows: The program
+ did not check memory bounds for any string operation. All places
+ where strings are copied with strcpy are replaced by dynamically
+ allocated strings (with xstrdup from kpathsea) or bounded string
+ operations. Fixed also manual string copy operations on special
+ strings. Fixed array buffer overflow in defpoint and fill special
+ operations.
+
+ Bumped version number up to 2.6p3.
+
+ * dvi2xx.h: Some fixed sized string arrays are pointers now, they
+ get dynamically allocated.
+
+ * config.h: Throw an error if kpathsea is not used. dvi2xx.c
+ had previously already kpathsea dependencies without protecting
+ them with #if KPATHSEA. We go that road further since upstream
+ does not exist any more.
