lib/thread: Move struct spdk_thread public in SPDK internal thread_get_pollers RPC which will be added in the upcoming patches will need to access all pollers each thread has. To avoid adding JSON related code into lib/thread/thread.c, expose struct spdk_thread internally among SPDK libraries and RPC code will access it. The next patch will expose struct spdk_poller internally among SPDK library for the same purpose.

thread: Change direct accesses to poller outside lib/thread to helper functions Most accesses to the struct spdk_poller outside lib/thread have been done via functions but a few direct accesses remain. Change these to indirect accesses by addinng a few helper functions as SPDK internal APIs. Add spdk_poller_get_name() to get the name of the poller. Remove spdk_poller_state_str() and add spdk_poller_get_state_str(). Exposing enum spdk_poller_state outside lib/thread is not really necessary. This removal requires us to update major SO version. Add spdk_poller_get_period_ticks() to get the period ticks of the poller. Add struct spdk_poller_stats and spdk_poller_get_stats() to get the stats of the poller.

rpc: Add thread_get_pollers RPC Add an new JSON RPC thread_get_pollers to retrieve pollers of all the threads. By adding a helper function spdk_poller_state_str(), output poller state as string to improve readability. Most of the code of thread_get_stats and thread_get_pollers are common and so unify these two RPCs as possible as we can. Sample output of thread_get_stats RPC in doc/jsonrpc.md was wrong because thread_get_stats doesn't output ticks. Fix this together.

thread: Add SPDK internal APIs spdk_thread_get_first/next_active/timed/paused_poller() The following patches will introduce red black tree to manage timed pollers efficiently but it will be based on macros available only in lib/thread/thread.c. Hence then it will be difficult to expose the internal of timed pollers tree outside the file. On the other hand, we do not want to include JSON into the file. Hence add a few SPDK internal APIs to iterate pollers list transparently. For spdk_thread_get_next_active/timed/pause_poller(), we omit the parameter thread and get it internally from poller->thread even if the names include the term "thread". This will be slightly cleaner.
