Let rpcgen(1) support an environment variable RPCGEN_CPP to find the C
preprocessor to run. Previously, it always ran /usr/bin/cpp, unless you
used the -Y option, and even then you could not set the basename. It
also attempted to run /usr/ccs/lib/cpp for SVR4 compatibility, but this
is obsolete, and has been removed.
Note that setting RPCGEN_CPP to a command with arguments is supported,
though the command line parsing is simplistic. However, setting it to
e.g. "gcc46 -E" or "clang -E" will lead to problems, because both gcc
and clang in -E mode will consider files with unknown extensions (such
as .x) as object files, and attempt to link them.
This could be worked around by also adding "-x c", but it is much safer
to set RPCGEN_CPP to e.g. "cpp46" or "clang-cpp" instead.

Correct a logic error in usr.bin/hexdump/conv.c, found by clang.
Whenever the conv_c() function encounters an incomplete multibyte char,
it peeks ahead. It also sets p to peekbuf, to indicate it is still
processing the incomplete character.
However, on the next retry, it compares buf against peekbuf, which
always returns false, since both buf and peekbuf are local char arrays,
whose addresses are never the same.
Fix this by comparing against p instead, which was the intention. Also
turn peekbuf into an array of u_char, to prevent conversion warnings.

r228827 fixed a problem where copying of NFSv4 open credentials into
a credential structure would corrupt it. This happened when the
p argument was != NULL. However, I now realize that the copying of
open credentials should only happen for p == NULL, since that indicates
that it is a read-ahead or write-behind. This patch fixes this.
After this commit, r228827 could be reverted, but I think the code is
clearer and safer with the patch, so I am going to leave it in.
Without this patch, it was possible that a NFSv4 VOP_SETATTR() could have
changed the credentials of the caller. This would have happened if
the process doing the VOP_SETATTR() did not have the file open, but
some other process running as a different uid had the file open for writing
at the same time.
