Here's another round of my pkt-line fixes. The more I dug, the more
interesting corners I found. :)

There are really several potentially independent topics rolled together
here. There are dependencies between some of them, so I tried to float
the most independent and non-controversial bits to the beginning. We may
want those as a separate topic to merge sooner, and have the rest as a
topic build on top.

Overall, the diffstat shows a reduction in lines (and I even added a few
dozen lines of comments), which is nice. The intent was to fix some bugs
and corner cases, but I found a lot of cleanup opportunities in the

The patches are:

  [01/19]: upload-pack: use get_sha1_hex to parse "shallow" lines

    New in this round; fixes a potential interoperability problem.

  [02/19]: upload-pack: do not add duplicate objects to shallow list

    New. Fixes a potential memory-consumption denial-of-service.

  [03/19]: upload-pack: remove packet debugging harness

    New. Optional cleanup, but later patches textually depend on it.

  [04/19]: fetch-pack: fix out-of-bounds buffer offset in get_ack

    New. Fixes a potential interoperability problem.

  [05/19]: send-pack: prefer prefixcmp over memcmp in receive_status

    New. Optional cleanup.

  [06/19]: upload-archive: do not copy repo name
  [07/19]: upload-archive: use argv_array to store client arguments

    New. Optional cleanup.

  [08/19]: write_or_die: raise SIGPIPE when we get EPIPE
  [09/19]: pkt-line: move a misplaced comment
  [10/19]: pkt-line: drop safe_write function

    The latter two were in the last round; but it's 08/19 that makes
    doing 10/19 safe. I think it's also a sane thing to be doing in
    general for existing callers of write_or_die.

    These can really be pulled into a separate topic if we want, as
    there isn't even a lot of textual dependency.

  [11/19]: pkt-line: provide a generic reading function with options

    This is an alternative to the proliferation of different reading
    functions that round 2 had. I think it ends up cleaner.  It also
    addresses Jonathan's function-signature concerns.

  [12/19]: pkt-line: teach packet_read_line to chomp newlines

    New. A convenience cleanup that drops a lot of lines. Technically
    optional, but later patches depend heavily on it (textually, and for
    splitting line-readers from binary-readers).

  [13/19]: pkt-line: move LARGE_PACKET_MAX definition from sideband
  [14/19]: pkt-line: provide a LARGE_PACKET_MAX static buffer

    New. Another cleanup that makes packet_read_line callers a bit
    simpler, and bumps the packet size limits throughout git, as we

  [15/19]: pkt-line: share buffer/descriptor reading implementation
  [16/19]: teach get_remote_heads to read from a memory buffer
  [17/19]: remote-curl: pass buffer straight to get_remote_heads

    These are more or less ported from v2's patches 6-8, except that the
    earlier pkt-line changes make the first one way more pleasant.

  [18/19]: remote-curl: move ref-parsing code up in file
  [19/19]: remote-curl: always parse incoming refs

    ...and the yak is shaved. More or less a straight rebase of their v2
    counterparts, and the thing that actually started me on this topic.

I know it's a big series, but I tried hard to break it down into
bite-sized chunks. Thanks for your reviewing patience.
