This reverts commit e7294d81.

This does not exist on xenial yet

find_package is for use inside the *Config.cmake files

To add public dependencies to the generated config, use e.g.

list(APPEND ${PROJECT_NAME}_PUBLIC_DEPENDENCIES "Boost COMPONENTS system thread chrono")

 - Add missing required dependencies for boost
 - Remove deprecated header. Also not needed on xenial

size_t has different types on 32 vs 64 bit systems. UL is correct for
64. Just use the ::size_type define to help it figure it out properly

(Currently untested as the recovery does not work in DeviceAccess. calling open() again just does nothing.)

Fixes #53

- Exception handling decorator and ThreadedFanOut send condition variable notificatios via the DeviceModule
- FanOut sends terminate to impl and all slaves.
Solves (some?) shutdown issues, but breaks bi-directional array test.

supposedly fixed implementation, but tests are conceptually broken and/or implementation cannot be terminated

Otherwise it is impossible to shut-down the server if the device could
not be opened at all or is in constant error state
