------------------------------
1.21 (July 2016)
    Yann E. MORIN (yann.morin.1998@free.fr): Buildroot [1] is a build-system
    targetting embedded devices. It is able to build toolchains for various
    architectures, based on the traditional GNU compiler collection gcc, the GNU
    binutils and various C libraries, such as GNU libc (glibc), uClibc [2] [3] or
    musl [4].

    glibc is a feature-full C library, which has had support for Yellow Pages
    (and the rest of the SUN RPC stuff) for a long time. However, circa the 2.14
    release, glibc stopped installing the RPC headers [5], on the principle that
    providing the RPC implementation would be better served by a third-party
    package, namely ti-rpc [6]. That did not happen in time, so installing the
    RPC headers from glibc was re-instated circa 2.16.

    uClibc (no longer maintained, replaced by a fork, uClibc-ng) is a fully
    configurable C library for embedded systems. It entirely lacks a SUN RPC
    implementation altogether.

    musl is standards-conforming, lightweight C library. It also entirely lacks a
    SUN RPC implementation.

    TI-RPC is a stand-alone package. It may or may not be available (because the
    user may not need SUN RPC stuff on an embedded device, for example). Besides,
    it is not yet as feature-full as the implementation in glibc, though for all
    practical means, it is totally useable.

    So, there are cases where a SUN RPC implementation is not available.

    This patch makes it so that the use of Yellow Pages is conditional on the
    presence of a SUN RPC implementation, by checking at ./configure whether the
    required header is present, and disabling the corresponding code if the
    header is missing.

    At the same time, the legacy, long unsupported AM_C_PROTOTYPES directive is
    also removed, as it makes recent-ish autoconf fail.

Log message:
Add SHA512 digests for distfiles for mbone category

Existing SHA1 digests verified, all found to be the same on the
machine holding the existing distfiles (morden).  Existing SHA1
digests retained for now as an audit trail.

1.20 (October 2013)
    Nick Birch (Nick.Birch@s-and-t.com): rtpsend -l (loop) flag does
    not work. Modified to rewind input file on feof if loop was
    set. Fails if length of line is greater than 2048
    characters. Increased to 4096 (sufficient for typical

    rtpdump: Put space after ext_data=<hex extension data> so that it
    can be parsed by rtpsend. parse_header doesn't comprehend the
    possible extension header. As a consequence any extension header
    data is also dumped twice. Once in the ext_data report and then a
    second time in the data report. Modify parse_header to return hlen
    that comprehends the extension header if present.

    The format for reporting contributing sources does not match the
    format accepted by rtpsend (i.e., reports "csrc[n] = xxxx" rather
    than "csrc[n]=0xxxxx"). Fixed. Note: the documentation is less
    than clear on the csrc syntax accepted by rtpsend.

1.19 (August 2010)
    Krzysztof Burghardt (krzysztof@burghardt.pl): "Wireshark
    implemented "rtpdump" file format in a bit different way, so
    cooperation beetwen those program is a bit problematic.
    Moreover rtptools compiled on i386 and amd64 have different size
    of file header (size of long in timeval is different)."
