d18e63206a mk/lib: add a check that major and minor version is set for libs.
Also, while we are here, consolidate setting SO_SUFFIX to one spot.

Previously, it was possible for a library to slip through
without an SO version.

6b40857206 lib: replace fprintf(stderr,) by SPDK_ERRLOG
SPDK_ERRLOG() uses spdk_log() procedure which is
customizable and redirectable, so it is preffered over fprintf.
It also prints source location which is useful.

e9aec6746a lib/thread: thread_poll() polls until the exiting thread is exited
Extract _spdk_thread_exit() from spdk_thread_exit() and
_spdk_thread_poll() calls _spdk_thread_exit() if the thread is in
the exiting state. spdk_thread_exit() changes to move the state to
the exiting state. The spdk_thread_poll() loop will end after the
thread moves to the exited state because the caller of
spdk_thread_poll() will check if the thread is in the exited state,
and break the loop if true.

If the user does not call spdk_thread_exit() explicitly, the reactor
has to terminate all existing threads at its shutdown. In this case,
multiple threads may have some dependency to release I/O channels or
unregister pollers. So the reactor has the large two loops, the first
loop calls spdk_thread_exit() on all threads, the second loop calls
spdk_thread_destroy() if exited or spdk_thread_poll() otherwise for
each thread until all threads are destroyed.

Besides, change the return value of spdk_thread_exit() to return
always 0. Keep it for ABI compatibility. Change ERRLOG to INFOLOG
for _spdk_thread_exit() because it is called repeatedly now. Remove
the check of I/O reference count from _spdk_thread_exit() because
_free_thread() cannot free I/O channel. Refine the unit test
accordingly.

Fixes issue #1288.

c9da0aecdc lib/thread: Ignore spdk_thread_exit() call after moving exited
Previously the caller had to check if thread is not exited when
it calls spdk_thread_exit().

Subsequent patches will change return type of spdk_thread_exit()
to void, and so include the check int spdk_thread_exit() in this
patch.

If spdk_thread_exit() is called when the thread is already exited,
collect INFOLOG and return normally.

This will make the next patch a little easier.

This is a preparation to the next patch which factors out the main
polling loop of _spdk_reactor_run() into a helper function reactor_run().

One of the subsequent patches will support CPU power saving by
adding sleep into reactor_run(). We should not insert sleep between
the main polling loop and getrusage() because now is got before
entering the main polling loop.

To put getrusage() into reactor_run(), we need to maintain last_rusage
in struct spdk_reactor and maintain g_rusage_period as a global
variable. This patch does these changes.

spdk_thread_poll returns only non-negative value now, and the return
code check is not reasonable now.  For just in case we may want to add
assert(rc >= 0) but compiler gives warning because rc is not used anywhere.
So just remove checking return code check here.

We noticed first that spdk_thread_destroy was called without spdk_thread
exit but this change removes spdk_thread_destroy.  So the issue is also
fixed together.

This returns true if all registered methods and aliases
are correct.  False means that an error like one of the
following occurred:

- duplicate method with same name
- alias specified for non-existant method
- alias specified for another alias

Also plumb this so that incorrect RPCs cause an SPDK
application to exit.

Note: there are cases where this would have been helpful
during the recent RPC renaming.

Fixes issue #940.

f7ddfcf743 reactor: allow spdk_reactors_fini() to be called without prior init
spdk_reactors_fini() is unconditionally called in spdk_app_fini()
at the end of every application and it currently throws a ton
of warning messages if the reactors weren't initialized yet [1].

Let's silence those warnings.

[1] $ spdk_tgt -c invalid.conf
[...]
*WARNING*: Called spdk_reactor_get() while the g_reactors array was NULL!
*WARNING*: Called spdk_reactor_get() while the g_reactors array was NULL!
*WARNING*: Called spdk_reactor_get() while the g_reactors array was NULL!
*WARNING*: Called spdk_reactor_get() while the g_reactors array was NULL!
*WARNING*: Called spdk_reactor_get() while the g_reactors array was NULL!

(Apparently SPDK_ENV_FOREACH_CORE iterates through 128 cores
if the dpdk env framework wasn't initialized. SPDK calls
spdk_reactor_get() on each core and that's what generates the
warnings)

1428692e1a lib/event: remove app.c dependency from loading json_config
Originally loading json_config using spdk_app_json_config_load_subsystem()
implied issuing start_subsystem_init RPC. This required a workaround
in the callback of RPC spdk_rpc_start_subsystem_init_cpl(), in order
to skip starting the app in json_config load path.

This made it difficult to load json_config without implicitly using
rest of the event framework. It will be usefull for example in
fio_plugin, which does not use the app.c API.

With change in this patch json_config load path directly calls
spdk_subsystem_init() C call.
Meanwhile start_subsystem_init RPC no longer needs a workaround
for json_config load path.
