    sysvipc: Fix a race with two clients creating shm with IPC_PRIVATE
    
    There was a subtle race condition in our `shmget()` wrapper with two
    clients trying to simultaneously create an shm region with `IPC_PRIVATE`
    and `IPC_EXCL`.
    
    The code relies on the `VIRTUAL_TO_REAL_SHM_KEY` API, which, in turn,
    uses the DMTCP shared data area to share and assign unique keys for SysV
    shm regions. The API returns -1 if the key does not exist in the DMTCP
    mapping. Now, if one client raced ahead and managed to create the region,
    it'd end up populating the DMTCP shared area with a "IPC_PRIVATE ->
    realKey" mapping. Later, when the other client would try to create its
    own shared memory region, the `VIRTUAL_TO_REAL_SHM_KEY` API would return
    the key corresponding the earlier created entry and the `shmget(IPC_EXCL)`
    call would fail with an `EEXIST` error.
    
    The fix here is to detect this special case of `IPC_PRIVATE` and use
    a process's real pid to create the shared memory region. This also
    preserves the semantics of `IPC_PRIVATE`.

Date:   Tue Feb 11 05:22:25 2020 -0800

    Added support for vfork syscall.
    
    The plugins clone their relevant data-structures during vfork_prepare
    phase that are then restored during vfork_parent phase when the parent
    returns from vfork. As a precaution, we also suspend all other threads
    prior to making vfork call. This is to ensure a consistent parent state
    across vfork.

    CoordinatorAPI: handle atfork events.

commit 89cc63d34e5b71205e16afd9de41bc85a3746bb1
Author: Kapil Arya <kapil.arya.17@gmail.com>
Date:   Sun Feb 9 16:02:00 2020 -0800

    Updated fork/atfork wrappers to use event hooks more extensively.
    
    This allows us to do proper layering within plugins without having to
    impose ad-hoc ordering constraints. For example, with proper layering,
    the UniquePid and CoordinatorAPI plugins can automatically do the right
    thing without having explicit invocations in the fork wrappers.

    Simplified file-wrappers.
    
    This consolidates file-wrappers in DMTCP core and create new events for
    open, close, dup, etc. This way, any plugin doesn't need to implement
    dozens of wrappers for capturing open/close.
    
    Merged wrappers weren't possible in 2.x branch due to improper plugin
    layering.
    
    A similar improvement is needed for fork+exec wrappers and popen/system
    metawrappers. We can then use our equivalent of atfork events more
    extensively.
