Add the --quic-bind-opts and --tcp-bind-opts long options to append
settings to all QUIC and TCP bind lines. This requires modifying the argv
parser to first process these new options, ensuring they are available
during the second argv pass to be added to each relevant "bind" line.
Add -b and -c options to the haterm argv parser. Use -b to specify the RSA
private key size (in bits) and -c to define the ECDSA certificate curves.
These self-signed certificates are required for haterm SSL bindings.
haterm_init.c is added to implement haproxy_init_args() which overloads
the one defined by haproxy.c. This way, haterm program uses its own argv[]
parsing function. It generates its own configuration in memory that is
parsed during boot and executed by the common code.
