8e60fa95cb libc/rpc: replace comma with semicolon when pertinent.
Uses of commas instead of a semicolons can easily go undetected. The comma
can serve as a statement separator but this shouldn't be abused when
statements are meant to be standalone.

Detected with devel/coccinelle following a hint from DragonFlyBSD.

478eb9e9ca libc/rpc: Make use of some xdr_* macros. (part 2)
xdr_rpcproc, xdr_rpcprog and xdr_rpcvers were broken in older
versions of FreeBSD but fixed in r296394.  Give them some use
hoping they help make the code somewhat more readable.

8f5cc69027 Fix up r300385
I accidentally glossed over the fact that tmp is manipulated via strchr, so
if we tried to free `tmp` after r300385, it would have crashed.

Create a separate pointer (tmp2) to track the original allocation of `tmp`,
and free `tmp2` if `p->nc_lookups` can't be malloced

75cd48a1c1 Use reallocf instead of malloc to fix leak with outbuf_pmap
The previous code overwrote outbuf_pmap's memory with malloc once per
loop iteration, which leaked its memory; use reallocf instead to ensure
that memory is properly free'd each loop iteration.

Add a outbuf_pmap = NULL in the failure case to avoid a double-free
at the bottom of the function.

d140ec33c7 Fix theoretical leak of netconfig(3) resources in svcunix_create(..)
In the event that the getconfig(3) call in svcunix_create is partly successful,
some of the netconfig(3) resources allocated might be leaked if the call returns
NULL as endnetconfig(3) wasn't called explicitly in that case. Ensure that the
resources are fully cleaned up by going to the `done` label, which will call
endnetconfig(3) for us.
