build: support OTP-18.0

[dch]

Support OTP-18.0.

configure & make checks LGTM, would be nice if somebody can check a linux?

• OSX Yosemite 14.4.0 https://gist.github.com/dch/14fd8f57fd806d94a1de
• FreeBSD 10.1 amd64 https://gist.github.com/dch/2387359cd6c21b9f4de9

A few more warnings appear as expected, crypto & time stuff.

erlang:now/0 as we know
calendar:local_time_to_universal_time/1 -> calendar:local_time_to_universal_time_dst/1
crypto:sha_mac/2 -> crypto:hmac/3
crypto:sha/1 -> crypto:hash/2
crypto:md5_init/0 -> crypto:hash_init/1
crypto:md5_update/0 -> crypto:hash_update/1
crypto:md5_final/0 -> crypto:hash_final/1

+1 works for me on Gentoo Linux

P.S. We also have another issue with building 1.x:

@dch could you check if such warning fix is fine for FreeBSD?

@kxepal this seems to be a linux issue according to https://lists.freebsd.org/pipermail/freebsd-standards/2004-March/000474.html FWIW I am building after running perl -pi -e 's/_BSD_SOURCE/_DEFAULT_SOURCE/g' src/couchdb/priv/Makefile.am src/ejson/Makefile.am src/snappy/Makefile.am test/etap/Makefile.am to clean those up, so far the build seems OK. gmake check takes a while...
