tcp: conditionally initializing log track for unbind

elog track is initialized when tcp open, bind, or syn rcvd
message is received. Logging tcp unbind event requires and
expects elog track is already initialized. If tcp debug
is enabled after the aforementioned 3 messages and the
first event that tcp logs is unbind, we crash because elog
track is not initialized.

Let's check the elog track is initialized yet or not
prior to logging an unbind event. If not, we initialize
it.

that potentially influence the app logic, could be starved if the
numbers of readers is significant.

To avoid this, always favor writers. Might require fine tuning in the
future.

memif: avoid double-close of the socket on client abort with un-read data

In some cases, there are two times the clib_file_del is called:

1) from memif_disconnect -> memif_socket_close call site in memif_master_conn_fd_error
2) the supposedly defensive code at the end of memif_master_conn_fd_error.

This was observed upon using of an artisanal memif client, which did not correctly drain the data written by VPP to the notification socket - a simple Ctrl-C in the client was enough to trivially reproduce the issue.
In real world scenario using the stock client this is expected to be a fairly narrow race condition.

The issue can be demonstrated as follows:

gre: Add support for GRE keys in the GRE plugin

The added feature enables the GRE plugin to create tunnels between the same endpoints,
distinguishing them by the "key" value. It uses the standard 'key'
parameter in the GRE header.
Changes have been made to add support for CLI and API to create tunnels with a "key" value.

The CLI syntax is as follows:
   create gre tunnel src src_IP_Address dst dst_IP_Address key key_value

All existing GRE functionalities, such as tunnel type and mode, remain unchanged.
GRE key support has been implemented for all non-ERSPAN tunnel types, including both IPv4 and IPv6.
Additionally, modifications were made to the GRE packet header, data structure, and inbound/outbound
packet processing to accommodate key configuration through CLI and API.
