* wget_http3_get_response returns the data that the http3 client stream has read
* all fprintf converted into debug_printf and error_printf
* fixed issues mentioned in the thread
* 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
* created http3.c and http3.h and implemented wget_http3_connection_st
* implemented http3 initialisation function to intialise the http3_connection struct
* shifted stream functions to a seperate stream.c file
* quic_write_read.c file created to demonstrate the working of wget_quic_read
and wget_quic_write hand in hand while configuring it to the QUIC ECHO server
* quic_write.c file created to make provide a example of write.
* A sample string initially pushed into the stream and then the stream
structure further utilised for sending the data over socket.
* Simplified the implementation of wget_quic_connect() and wget_ssl_quic_connect()
* Segregated the function wget_quic_connect into wget_quic_connect and wget_quic_handshake
* Restored signatures of wget_ssl_open and wget_ssl_init and created new functions for quic related SSL set up.
* Moved all the quic related file to a new file named quic.c from net.c
* net.c : wget_quic_connect edited to use DNS for resolving
* dns.c : resolve and wget_dns_resolve edited to resolve for SOCK_DGRAM as well as SOCK_STREAM
*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
* libwget/http.c: Add function wget_http_cidr_match to support
CIDR IP method for no_proxy
* unit-tests/test.c: Add testcases to verify the functionality
of the above function
Fixes#615
* configure.ac: Enable DANE if libgnutls-dane is installed,
add option --without-libdane.
* docs/wget2.md: Add docs for option --dane.
* include/wget/wget.h: Add WGET_SSL_DANE.
* libwget/ssl_gnutls.c: Include include <gnutls/dane.h> if requested,
(struct config): New member 'dane',
(wget_ssl_set_config_int): Set value for dane via WGET_SSL_DANE,
(wget_ssl_open): Call dane_verify_session_crt().
* src/options.c (options): Add entry for --dane,
(init): Set config.dane via wget_ssl_set_config_int().
* src/wget_options.h (struct config): Add member 'dane'.
* include/wget/wget.h: Add WGET_SSL_REPORT_INVALID_CERT macro
* libwget/ssl_gnutls.c: Change certificate related error_printf() calls, for error_printf_check()
* libwget/ssl_openssl.c: Consider the case WGET_SSL_REPORT_INVALID_CERT in wget_ssl_set_config_int()
* libwget/ssl_wolfssl.c: Change certificate related error_printf() calls, for error_printf_check()
* src/options.c: Admit quiet as a valid value on --check-certificate
* src/wget_options.h: Move check_certificate from bool to an enum type (with enabled, disabled and log_disabled as values)
