svn rev #19641: trunk/src/appl/bsd/

[raeburn@MIT.EDU]

Commit By: raeburn
Log Message: 
* v4rcp.c (kstream_write): Allocate buffer space if it hasn't been
allocated, in the encrypting case, even if outlen is zero.  While I
don't believe this can ever happen, it requires careful examination of
lots of code paths to figure it out.  This change doesn't fix a
serious bug, but makes the analysis simple.  Also, don't bother with
separate code paths for malloc vs realloc depending on the previous
values; we can just use realloc always.

Thanks to Domagoj Babic for pointing out the (false but
understandable) null-pointer problem.
