Add patch for kdoctools/xml2man.cpp, similar to xslt.cpp patch.

Bump PORTREVISION just in case this is needed.

From Mikhail Teterin:

> In essence, the code  reads the whole file into a  buffer. It then tries
> to  turn that  buffer into  one of  qt's string-objects  (QCString). The
> class'  constructor  they chose  assumes,  it  is  passed a  valid  (aka
> \0-terminated) string and goes through  the buffer looking for the first
> 0-byte. The  file itself  does not  contain any,  so it  happily wonders
> behind the real end of the buffer  until it either finds a stray 0-byte,
> or seg-faults, trying to read a wrong page.

> file size -- unless  the 0-byte happens to be right there  at the end of
> the  buffer.  Apparently, the  lamer, who  wrote it,  noticed  something

> allocates the private storage (I hate  C++ for all this buffer copying),
> appends  the 0-byte  and creates  the object  of the  expected size.  No

Thanks to Mikhail for his debugging on this problem; this patch further
removes the hazard of meinproc coredumps.
