r302550:

Deobfuscate cleanup path in clnt_dg_create(..)

Similar to r300836 and r301800, cl and cu will always be non-NULL as they're
allocated using the mem_alloc routines, which always use
`malloc(..., M_WAITOK)`.

Deobfuscating the cleanup path fixes a leak where if cl was NULL and
cu was not, cu would not be free'd, and also removes a duplicate test for
cl not being NULL.

r302551:

Deobfuscate cleanup path in clnt_vc_create(..)

Similar to r300836, r301800, and r302550, cl and ct will always
be non-NULL as they're allocated using the mem_alloc routines,
which always use `malloc(..., M_WAITOK)`.

CID: 1007342

r302552:

Convert `svc_xprt_alloc(..)` and `svc_xprt_free(..)`'s prototypes to
ANSI C style prototypes

r302553:

Don't test for xpt not being NULL before calling svc_xprt_free(..)

svc_xprt_alloc(..) will always return initialized memory as it uses
mem_alloc(..) under the covers, which uses malloc(.., M_WAITOK, ..).

MFC r258578, r258580, r258581 (by hrs):
Replace Sun RPC license in TI-RPC library with a 3-clause BSD license
with the explicit permissions.

MFC r259842:

Remove some unused static const strings under sys/rpc, which have never
been used since the initial commit (r177633).

MFC r259843:

Move a static const variable to the #if 0 part where it is only used.
(Note the #if 0 part has been inactive since the initial commit,
r177633, so maybe it should be removed altogether).
