[krbdev.mit.edu #6486] SVN Commit

[Tom Yu via RT]

In util/support/utf8_conv.c, the SWAP16 macro is invoked with an
argument that has side effects.  On platforms where SWAP16 can
evaluate its argument twice (including platforms where utf8_conv.c
creates a fallback definition for the SWAP16 macro), this can cause a
read overrun by a factor of two.

Rearrange the data flow to avoid calling SWAP16 with an argument that
has side effects.
