[svn-r8708] Purpose:

This fixes bug mozilla_145

Description:
Output from h5dump is truncated on SGI

Solution:
Revise h5tools_str_append.

Changed the check for the return value from vsnprintf to handle
overflows correctly.

Added a special check for the case where HAVE_VSNPRINTF is not
defined. (Windows doesn't have this function.)  Will abort() if
memory is overwritten.  This overflow appears to be rare, but
if we get reports of hitting this abort() we can try a more
robust solution for platforms lacking vsnprintf.

Platforms tested:
arabica
verbena
hirdls (IRIX64 serial)
windows 2000
