Fixes for build errors under Windows and compiler warning under Linux

include/m_string.h:
  new macro like LINT_INIT but for struct. In m_string.h because bzero() becomes available only there
storage/maria/ma_check.c:
  compiler error under Windows (declaration after statements...)
storage/maria/ma_key.c:
  trnman.h is not in include/ but in storage/maria
storage/maria/ma_sp_key.c:
  trnman.h is not in include/ but in storage/maria
storage/maria/ma_write.c:
  avoid compiler warning (org_key.flag may be used uninitialized)
