2017q1 release

As this is our first official release it covers the last 12 months of
development since 2016-04-01.

Breaking changes:

• Fix implicit conversion of Flags
• Refactor buffer to display_buffer in BufferedGraphicDisplay
• Fix spelling of SpiMaster::acquire
• Namespace architecture/util.hpp macros
• stm32f7_discovery renamed to stm32f746g_discovery

Major features:

• Runtime error model using assertion handlers
• Memory traits to heap regions and allocators
• TLSF allocator
• Link against newlib-nosys and newlib-nano
• Unified interrupt declaration conventions
• Black Magic Probe programming support
• ARM Cortex-M7 with double precision FPU

• GPIO connect on STM32F1 is broken. They can be remapped only in groups,
  however, the API allows invalid remapping. This cannot be fixed without
  introducing a new API for that. See #178 for discussion.
  A solution has been tested for modm, but isn't ready for xpcc.
