Ensure that all I/O channels created for migration are given names
to distinguish their respective roles.

The command :
migrate tcp:localhost:
currently segs; fix it so it now says:
error parsing address 'localhost:'
and the same for -incoming.

Code of inet socket & unix socket is merged together.
Also add some newlines, make code block well separated.

Apply the following renames for starting incoming migration:
process_incoming_migration -> migration_fd_process_incoming
migration_set_incoming_channel -> migration_channel_process_incoming
migration_tls_set_incoming_channel -> migration_tls_channel_process_incoming
and for starting outgoing migration:
migration_set_outgoing_channel -> migration_channel_connect
migration_tls_set_outgoing_channel -> migration_tls_channel_connect

This extends the migration_set_incoming_channel and
migration_set_outgoing_channel methods so that they
will automatically wrap the QIOChannel in a
QIOChannelTLS instance if TLS credentials are configured
in the migration parameters.
This allows TLS to work for tcp, unix, fd and exec
migration protocols. It does not (currently) work for
RDMA since it does not use these APIs, but it is
unlikely that TLS would be desired with RDMA anyway
since it would degrade the performance to that seen
with TCP defeating the purpose of using RDMA.
On the target host, QEMU would be launched with a set
of TLS credentials for a server endpoint
$ qemu-system-x86_64 -monitor stdio -incoming defer \
-object tls-creds-x509,dir=/home/berrange/security/qemutls,endpoint=server,id=tls0 \
...other args...
To enable incoming TLS migration 2 monitor commands are
then used
(qemu) migrate_set_str_parameter tls-creds tls0
(qemu) migrate_incoming tcp:myhostname:9000
On the source host, QEMU is launched in a similar
manner but using client endpoint credentials
$ qemu-system-x86_64 -monitor stdio \
-object tls-creds-x509,dir=/home/berrange/security/qemutls,endpoint=client,id=tls0 \
...other args...
To enable outgoing TLS migration 2 monitor commands are
then used
(qemu) migrate_set_str_parameter tls-creds tls0
(qemu) migrate tcp:otherhostname:9000
Thanks to earlier improvements to error reporting,
TLS errors can be seen 'info migrate' when doing a
detached migration. For example:
(qemu) info migrate
capabilities: xbzrle: off rdma-pin-all: off auto-converge: off zero-blocks: off compress: off events: off x-postcopy-ram: off
Migration status: failed
total time: 0 milliseconds
error description: TLS handshake failed: The TLS connection was non-properly terminated.
Or
(qemu) info migrate
capabilities: xbzrle: off rdma-pin-all: off auto-converge: off zero-blocks: off compress: off events: off x-postcopy-ram: off
Migration status: failed
total time: 0 milliseconds
error description: Certificate does not match the hostname localhost

The unix.c file will be nearly the same as the tcp.c file,
only differing in the initial SocketAddress creation code.
Rename unix.c to socket.c and refactor it a little to
prepare for merging the TCP code.
