e4070ee0e0 so_ver: increase all major versions
To allow SO_MINOR updates on LTS for the whole year it is supported,
the major version for all components needs to be increased.
This is to prevent scenario where two versions exists with matching
versions, but conflicting ABI.
Ex. Next SPDK release adds an API call increasing the minor version,
then LTS needs just a subset of those additions.

Increasing major so version after LTS, allows the quarterly releases
to update versions as needed. Yet allowing LTS to increase minor
version separately.

Disabled test for increasing SO version without ABI change, as
that is goal of this patch. This check shall be removed with SPDK 21.04
release.

This patch:
- increases SO_VER by 1 for all components
- resets SO_MINOR to 0 for all components
- removes suppressions for ABI tests

b48596efbc lib/nbd: Remove errno != EWOULDBLOCK in nbd_socket_rw
In this commit (a1d4a714b2),
we refactor the code but introduce the new error comparison.

And it causes the hang issue in some cases for RPC, so remove
it.

aa4b4e17f3 nbd: Continue revising the nbd subsystem fini logic
After carefully checking the code, spdk_nbd_stop should
be called in the same spdk thread which creates the io_channel.
Usually, the spdk thread which handles the rpc call should be
same with the thread which finalizes the thread. But it could
be different. So adding another async call to make sure we should
call spdk_nbd_stop on the same spdk thread.

d2704a0f48 lib/nbd: Fix the nbd_cleanup_io logic
1 For nbd_io in received list, we should not call nbd_put_io directly.
We should still let those I/O be executed by the lower bdev layer in SPDK.

2 For nbd io in executed_io_list, we should not directly put the nbd device.
The correct way is that we should write the io response to the kernel NBD
device. Then the nbd device will not hang.

de1d0f8fe9 jsonrpc: don't check returned value from spdk_jsonrpc_begin_result()
As spdk_jsonrpc_begin_result() is not allowed to return NULL we can
remove these checks. We didn't have any tests cases that goes this path
anyway.

36e8c20fe9 nbd: avoid impact to device setup by other task
Use NBD_SET_SOCK to check whether the nbd device is setup
by other process or whether nbd kernel module is ready
before other nbd ioctl operations. This can avoid bad
influence to the nbd device setup by other process.

d8f5fead29 nbd: avoid unlimited wait for device busy
The ioctl NBD_SET_SOCK can return EBUSY on conditions not
only the kernel module hasn't loaded entirely yet, but
also the nbd device is setup by another process, which will
lead the poller's infinite polling.
This patch will wait only 1 second if device is busy.
