* libwget/ssl_quic_gnutls.c (wget_ssl_close_quic): new function:
deinit gnutls_session_t object.
* libwget/quic.c (quic_stream_mark_acked): free node after dequeue.
(wget_quic_deinit): deinit gnutls_session_t object.
* libwget/queue.c (wget_queue_free): remove unused function.
(wget_queue_free_node): new function: remove a node and its inner
contents.
(wget_queue_dequeue_transmitted_node, wget_queue_dequeue_data_node):
return outer node object, instead of inner data. This makes it easier
to free the full node & its contents after inspection.
(wget_queue_enqueue): fix: unnecessary allocation.
* libwget/http3.c (wget_http3_send_request): fix: free vector after
use.
(wget_http3_get_response): free full node after use.
(wget_http3_get_response_cb): new function.
* libwget/bytes.c (wget_byte_new): free bytes struct on error.
* include/wget/wget.h (wget_queue_free): remove unused function.
(wget_queue_free_node): new function.
(wget_queue_dequeue_transmitted_node): change return value.
(wget_queue_dequeue_data_node): change return value.
In addition, create new function wget_queue_free_node.
Introduce a new function that will free the node and its contents all at once.
* implementated very basic callback functions for http3
* implemented wget_http3_send_request to create a http3 requests
* reimplemented the internal working of wget_queue_peak_untransmitted
* example code for sending http3 request implemented
* Added a bool in wget_byte struct named transmitted
* Implemented function wget_queue_peak_untransmitted_data
* This function will return first untransmitted byte
* Implemented wget_http3_deinit
*net.c : wget_quic_connet function implemented
*ssl_gnutls.c : wget_ssl_quic_open and wget_ssl_quic_open functions implemented
*queue.c: Implementation of queue using linked list
