Jeff King df1ed03a6f remote-ext: simplify git pkt-line generation
We format a pkt-line into a heap buffer, which requires
manual computation of the required size, and uses some bare
sprintf calls. We could use a strbuf instead, which would
take care of the computation for us. But it's even easier
still to use packet_write(). Besides handling the formatting
and writing for us, it fixes two things:

  1. Our manual max-size check used 0xFFFF, while technically
     LARGE_PACKET_MAX is slightly smaller than this.

  2. Our packet will now be output as part of
     GIT_TRACE_PACKET debugging.

Unfortunately packet_write() does not let us build up the
buffer progressively, so we do have to repeat ourselves a
little depending on the "vhost" setting, but the end result
is still far more readable than the original.

Since there were no tests covering this feature at all,
we'll add a few into t5802.
