lib/fsdev: mount and umount API introduced

This patch introduces SPDK fsdev spdk_fsdev_mount and spdk_fsdev_umount
APIs, the SPDK fsdev analogues of FUSE_INIT and FUSE_DESTROY.

The corresponding fsdev module handlers are optional (as any other),
however failing the INIT handler will fail the FUSE_INIT and therefore
the host's mount.

The spdk_fsdev_open() API doesn't get the open_opts parameter anymore.
It became mount_opts now.

env: add SPDK_ENV_NUMA_ID_ANY and replace socket_id with numa_id

We will try to avoid further proliferation of "SOCKET_ID" to refer
to a NUMA socket ID moving forward, and just use "NUMA_ID" to avoid
confusion with TCP sockets.

Change all of the existing in-tree SPDK_ENV_SOCKET_ID_ANY uses to
SPDK_ENV_NUMA_ID_ANY, but keep the old #define around, at least for
now. Also change all 'socket_id' parameters to 'numa_id'.

We still have spdk_env_get_socket_id(), we will need to keep this
but next patch will add spdk_env_get_numa_id().

lib/fuse_dispatcher introduced

The FUSE dispatcher is an auxiliary library that manages an underlying fsdev
and implements the FUSE <=> fsdev API translation.

It provides an iovec-based API according to virtio-fs spec, where the iovecs
contain the FUSE-specific structures (IN and OUT).

So, the FUSE dispatcher:
- parses the FUSE requests
- opens and closes an fsdev upon the FUSE_INIT and FUSE_DESTROY requests
correspondingly
- translates the FUSE requests into the corresponding spdk_fsdev_op_... API
calls
- handles the FUSE responses
