d92f0f75ca log: rename SPDK_TRACELOG to SPDK_DEBUGLOG
This matches the name to the behavior and prepares for addition of a new
log macro for "info" log level.

1be7a80c2d jsonrpc: remove pointless 'continue' statement
This was left behind in commit 122e28465 ("jsonrpc: move closed conn
handling before poll()").  It is not needed now that the closed
connection handling is in a loop by itself.

2bcabb2004 jsonrpc: remove incorrect handling for send() == 0
recv() returns 0 when the remote end of the connection is shut down, but
there is no such rule for send().  Remove the incorrect treatment of
send() returning 0 as an error.  The remaining code will treat a send()
return value of 0 as a non-error condition and will continue to work
correctly.

cc7407947b jsonrpc: avoid calling poll() with a closed fd
If a connection is closed by the remote end, the JSON-RPC server could
potentially call poll() on the pollfd containing the invalid file
descriptor.  Rework the logic so that the pollfd's fd field is set to a
negative value so that poll() will ignore it until the connection is
fully cleaned up by spdk_jsonrpc_server_conn_remove().

Also add handling for the potential error conditions returned by poll()
so that if something does go wrong, the server doesn't get stuck polling
a broken pollfd forever.

122e284652 jsonrpc: move closed conn handling before poll()
Make sure that we check any closed connections even if poll() indicates
that no sockets are ready, since closed sockets won't ever trigger
poll().

35d46267b8 jsonrpc: remove support for batch requests
This will greatly simplify the implementation of asynchronous requests,
and asynchronous requests also allow clients to submit multiple
overlapped requests, making batches unnecessary for executing multiple
RPCs at once.  Additionally, our RPC client (scripts/rpc.py) does not
use batch requests.

2bdec64fbf jsonrpc: modify API to pass request to handler
This will enable asynchronous request handling in a future patch, and it
also removes the need for the RPC handlers to know about request id and
the JSON-RPC rules about notification-only requests.

d27b24c94b log: split internal TRACELOG macro into new header
The SPDK_TRACELOG macro depends on a CONFIG setting (DEBUG), so it
should not be part of the public API.

Create a new include/spdk_internal directory for headers that should
only be used within SPDK, not exported for public use.
