[Development] QtCS: Long Term Release discussion

Last year's notes[1]

Qt 5.5 will be the last release to support:
     *  GCC 4.6
     *  OS X 10.7
     *  Windows Vista
     *  WIndows Embedded Compact 7
     *  QNX 6.5
     *  Qt WebKit, Qt Script, Qt Quick 1

Therefore, we'd like to have a long-term support release that allows people 
who cannot upgrade to remain for some longer time in an official release. 
Additionally, we'd like to sync up with Ubuntu's LTS releases (next is 16.04) 
- other distros are mostly focused on servers (RHEL, SLES) or don't actively 
depend on Qt anyway.

Qt 5.5 would be ideal - but we'd need to support the old Qt CI system for 
longer. So we're targetting that *Qt 5.6* will be the first LTS release.

Other notes:
     *  We will keep a Linux builder building 32-bit to make sure everything 
works - *no binary packages for Linux 32-bit*
     *  We do not build for OS X 32-bit, but we'll accept packages
     *  We do need to introduce a static builder to ensure things work. We 
need to document that static requires more complexity to make a working 
application and it's only tested with qmake.
