EMBB-453

   - Do not use lists
   - Remove HelpScan
   - Release memory to memory manager when destructed (before that, memory had to be released by the memory manager in its destructor).
   - Avoid stdlib algorithms

The comparison of absolute times was done in a wrong way such that
unsigned int overflows occured in the windows implementation when
the time to wait for had been passed already. A very big time to
wait for resulted, i.e., a deadlock.

EMBB-466

portability: changed all checks for platform specific defines to checks for EMBB_* defines, fixed affinity implementation for FreeBSD

  (this probably works on MacOS too, but not tested yet)

While on it, fix error message. The missing include file
is not the root cause of the problem. The missing implementation
of embb_core_count_available() is.
