0b8ac37450 mdbx: reduces number of getpid() calls for checking PID against fork().
PID check could be ommited:
 - on Linux when madvise(MADV_DONTFORK) is available. i.e. after the fork()
    mapped pages will not be available for child process.
 - in Windows where fork() not available.

35f95e8ca2 mdbx-windows: always susppend local threads while resize DB (workaround for Windows kernel bug).
We should not concern about performance on Windows platform,
it just unreasonable. Therefore just always suspend the local
threads to avoid this issue.
