Pull request description:

  This PR upgrades `expat` and `qt` in depends. The intention is to upgrade Qt in master to the latest point release of the current Qt LTS. This change can then be back-ported to the 0.17 branch (wether it makes it into 0.17.1 or not).

  Then, sometime before the 0.18.0 release, we could move to using Qt 5.12+ in depends (which is also LTS). That discussion, as well as minimum supported Qt versions is in #13478.

  ### Qt 5.9.7
  [Release announcement](https://blog.qt.io/blog/2018/10/23/qt-5-9-7-released/)
  [Changelog](https://bugreports.qt.io/browse/QTBUG-70888?filter=20149)

  ### Expat 2.2.6
  * Avoid doing arithmetic with NULL pointers in XML_GetBuffer
  * Fix 2.2.5 regression with suspend-resume while parsing a document like <root/>

  Full changelog [here](https://github.com/libexpat/libexpat/blob/R_2_2_6/expat/Changes)

  https://github.com/bitcoin/bitcoin/pull/14849/commits/a46c8476e9598742e52944b6270b1854c8f500a2 disables a bunch of qt features we aren't currently using. This speeds up the qt depends build slightly (also decreases the size of the built `qt-5.9.7` tar by about 2%). The disabling is somewhat unintuitive, hence `[wip]` until after a travis run and gitian build.
