CalmarBen/Remmina:REM-3567-memory-grow into master

changes regarding issue #3567 (closed)

  • commit#1: by adding memory_trim(0) on connection end, the problem is minimized (in my test, without change +~200Mb on each connection close, with changes +~20Mb)
  • commit#2: setting MALLOC_ARENA_MAX=2 by default (if environment variable not already set) minimized it a little bit more.
