HEADSUP: it is my intention to remove the "source", "outfile", and
"observe" top-level commands from scamper's control socket interface
in a future release, based on my hunch that no one uses those
features.  Please contact me if you do use those features.

configure:
* better tests for zlib, libbz2, and liblzma that check for both
  libraries and headers.
* change --with-sc_uptime, --with-sc_hoiho, and --with-tests to be
  --enable-sc_uptime, --enable-sc_hoiho, and --enable-tests
* disable maintainer mode, pass foreign to AM_INIT_AUTOMAKE

scamper:
* remove reading regular files from poll/select/epoll/kqueue path,
  which fixes reading regular input files (-f option to scamper) using
  epoll or kqueue
* fix reading stdin as input (-f option to scamper) when using
  epoll (catch EPOLLHUP)
* add DNS server to host signature, add host path for scamper_task_find
* rework scamper_osinfo to work with malformed release names (uname -r)
* dealias: do not crash on malformed prefixscan and bump commands
* dealias: fix memory leak of probedefs on malformed commands
* sting: fix memory leak of recorded packets
* remove tsps input method (-O tsps option to scamper)
* update manual page

libscamperctrl:
* link against list.o and splaytree.o so that the library is self-contained
* fix memory leak when task is not accepted
* API improvements

libscamperfile:
* fix memory leak when reading SOA/MX from warts file
* fix memory leak when reading PMTUD traceroute structures from warts file
* sting: fix memory leak of recorded packets

sc_analysis_dump, sc_warts2pcap, sc_wartscat, sc_wartsfilter:
* link against list.o/utils.o so that these utilities are not reliant on
  those symbols being exported from libscamperfile

sc_prefixprober:
* allow compression type to be specified using -O
* free scamper_addr_t as each are removed from the list to probe

sc_remoted:
* catch EPOLLHUP with epoll

sc_warts2text:
* fix memory leaks

sc_wartsdump:
* fix memory leaks
* link against utils.o so that sc_wartsdump is not reliant on those
  symbols being exported from libscamperfile
