Add an unique ID for each created SPDK thread. Use a single 64 bits
variable, g_thread_id, and guard its update by the global mutex
g_devlist_mutex. For our safety, further thread creation is not
allowed if g_thread_id rolls over, and request user to restart SPDK
application.
Besides, as a minor update, move the debug log down and add ID to it
in spdk_thread_create(), and ID is added to thread_get_stats RPC and
framework_get_reactors RPC.
The thread ID will be used to set the cpumask of the running thread
to the specified value in the subsequent patches.

spdk_reactor_enable_framework_monitor_context_switch and
spdk_reactor_framework_monitor_context_switch_enabled had been
a little long and not easy to get the meaning.
spdk_framework_enable_context_switch_monitor and
spdk_framework_context_switch_monitor_enabled will be a little
more concise, and hence change the names accordingly.

Add an new RPC `framework_get_reactors` to retrieve list of all
reactors. Running threads on each reactor are included
in the output. Update jsonrpc.md and CHANGELOG accordingly.

Thread's core affinity had not been visible to users. This patch
adds thread's core affinity information to the existing
thread_get_stats RPC. We can create an new RPC to retrieve
thread's core affinity information but using thread_get_stats
RPC will be enough for now.
Besides, the name of SPDK thread 0 is not reactor_0 but app_thread
now. So fix it together in this patch.

These directories fit in with the module concept we are forming inside
of SPDK. Essentially modules are derivative or specialized libraries that
rely on a general or core library.
