This reverts commit 554c76f7, reversing
changes made to fc660db0.

   - 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

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

source directory.
With this patch one can build in tree or put the build-dir anywhere.
