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`.

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.

Compiler warnings w/ -m32 for coordinatorapi.cpp
- Util::readAll() and Util::writeAll() return ssize_t, which is a
signed int when compiled in 32-bit mode. When the result is
compared with a uint64_t, the gcc-4.8 compiler issues warnings
about comparing a signed and unsigned int expression. So, we
cast the other comparison expression to an 'ssize_t'.

Fix: dmtcp_launch, pause: applic. main, ckpt timer
- This fixes a long pause (e.g., GDB) when at main() in the target application.
The ckpt interval timer goes off at this time
- In addition, it fixes a problem of: dmtcp_launch and break at execvp (e.g., in GDB)
In this case also, the ckpt interval timer goes off, and the workerState is not yet running
or the last worker exited and the worker state is UNKNOWN

This construct relieves us from the worries of releasing a lock during
early exits from a wrapper function.

Include barrier name in DmtcpMessage.
Sometimes the process might get killed after writing DmtcpMessage but
before writing "extra-data" on the coordinator socket. Currently, the
coordinator is not robust enough to detect it. The fix is to send the
barrier name as part of DmtcpMessage.
Since the DmtcpMessage struct is of static size, we are imposing a
limit of 64 characters for the barrier names.
