svn rev #21006: branches/mskrb-integ/src/lib/gssapi/krb5/

[lhoward@MIT.EDU]

Commit By: lhoward
Log Message: 
Refactor. Allow for the possibility of implementing
gss_wrap_iov()/gss_unwrap_iov() with a single BUFFER_TYPE_STREAM which
does not have valid buffers for the header, trailer and pad (although
these would still need to be supplied to the underlying implementations).
