8eef5183d3 bdev: remove spdk_bdev_poller_start() lcore option
Always start bdev pollers on the calling core.

This removes the lcore concept from the bdev poller abstraction and
simplifies the job of spdk_bdev_initialize() callers providing their own
poller and event implementations.

All callers except the NVMe bdev hotplug poller already used the current
core as the parameter.  The NVMe HotplugPollCore option was undocumented
and unused in any of the tests or example configuration files, so it
should be safe to remove.

7aba48fe1e subsystem: move allocation of subsystem_init event to subsystem
Previously two spdk_events were allocated in spdk_app_start().

Now app allocated spdk_event for function to be called after
initialization is complete. Meanwhile subsystem allocates
its own spdk_event.

c588baab29 reactor: add pid to names for rings and mempools
This is required for using the event framework
in multi-process mode since they must be unique
across the group of processes..

Currently the stub app calls into the env layer
directly, bypassing the event framework, so this
issue would only be seen with multiple secondary
processes using the app framework.  Some future
changes will change the stub app to use the event
framework which necessitates this change immediately.

4c0eaac47a bdev: Create a separate bdev subsystem library
Much like bdev modules inside the bdev directory,
add a subsystems directory inside of event. The subsystem
specific code for the bdev library is placed in to
a separate library in that directory, breaking the
strict dependency of the bdev library on the event subsystem
code.

356e2ab20f event: remove spdk_app_init
In this patch, spdk_app_init will be merged into
spdk_app_start.
Due to this change, we need to change event_perf
to use spdk_app_start, since we cannot use spdk_app_init
anymore. So the related changes for event_perf is to
make it work with reactor framework.

choice.
