[Depends] Bump Boost, miniupnpc, ccache & zeromq #6980

Boost 1.59.0 Change-log See #6937

Miniupnpc 1.9.20151026 Includes @laanwj's string handling/overflow fixes. See https://github.com/miniupnp/miniupnp/pull/157 Changes:

2015/10/26:
  snprintf() overflow check. check overflow in simpleUPnPcommand2()
2015/10/25:
  fix compilation with old macs
  fix compilation with mingw32 (for Appveyor)
  fix python module for python <= 2.3

ccache 3.2.4 Fixes a regression related to compiling on some Macs

Fixed build error related to zlib on systems with older make versions (regression in ccache 3.2.3).
Made conversion-to-bool explicit to avoid build warnings (and potential runtime errors) on legacy systems.
Improved signal handling: Kill compiler on SIGTERM; wait for compiler to exit before exiting; die appropriately.
Minor fixes related to Windows support.
The correct compression level is now used if compression is requested.
Fixed a bug where cache cleanup could be run too early for caches larger than 64 GiB on 32-bit systems.

Interesting - upnpc fails on macosx:

Looks like they switched to using libtool for creating the static lib. "libtool" in this case is osx's library tool, not the gnu libtool it's finding. Thanks Apple!

This should fix:

Added another commit with @theuni's miniupnpc fix. @theuni If we're bumping depends, are there any others we should look at for 0.12.0? The 4.0.x release of zeromq is now retired, with 4.1.3 being the latest. Should we bring our package (4.0.4) up to the latest release of the retired branch (4.0.7)? Or would we leave it and move to 4.1.x in future?

@fanquake For libraries like ZMQ, which are still in quick iteration development, static linking is unfortunately kind of suboptimal. I'd say bump it, otherwise by the time 0.12 final is out we're speaking a dead language :)

@theuni is this ok for merging?

@theuni ping?

ut ACK.

@laanwj @theuni I've added another commit that updates config.guess and config.sub to their latest revisions. Minor changes to both files.
