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.

Defined callback for spdk_poller to adapt itself to
set interrupt or poll mode. The callback can
be registered to spdk_poller by new function
`spdk_poller_register_interrupt`
Interrupt callback operations for period poller are implemented,
so period pollers now are interruptable.

spdk_thread_set_interrupt_mode can get spdk_thread run
between intr and poll mode. It is only valid when thread
interrupt facility is enabled by
spdk_interrupt_mode_enable(). Currently, this function
is limited that no poller is registered to the spdk_thread.

Each reactor and each thread is assigned with one fd group.
At the same time, each thread is treated as one interrupt source
registered into its corresponding reactor.
The egrp function for reacotr is the only block point waiting
for events.
