Philippe Waroquiers e52f0e1de0 * none/tests/linux/mremap3.vgtest : new test

mremap3.c based on testcase provided by Jan Engelhardt
* coregrind/m_syswrap/syswrap-generic.c
  - The two 'no-thrash checks' that were introduced to fix bug #129866
    were (probably) broken when adress space manager was reworked.
    The new VG_(am_get_advisory_client_simple) returns NULL for a free
    segment, but the check was based on checking not NULL and then
    that the state is free.
    => replaces these two local checks by a call to the new
    am Bool VG_(am_covered_by_single_free_segment) function.

* coregrind/pub_core_aspacemgr.h
  coregrind/m_aspacemgr/aspacemgr-linux.c
  - new function Bool VG_(am_covered_by_single_free_segment)
