svn commit: r334656 - head/stand/libsa

[Ian Lepore]

New Revision: 334656
URL: https://svnweb.freebsd.org/changeset/base/334656

Log:
  Add vsnprintf() to libsa.  Alpha-sort the printf prototypes in stand.h.
  
  I'm not sure why the v*printf() functions in libsa return void instead of
  int, but this maintains that convention for the new function.
