proto_run_command() invocation in order to prevent the shell from
improperly splitting the command arguments on $IFS.

Backported upstream patches that fix this.
Removed local patch that fixes libp11 with version 0.4.7, which is not
used anymore. Upstream has a different solution.
License fixes and Makefile cleanups.

That is, since we don't require gssapi or libpskc, avoid
accidental builds with it.

"token_mode" add support for "script", which execute "token_script" to
get the password. Some token is not supported by OpenConnect natively,
e.g. "MobilePass" or "Softoken II" used in Cisco VPN

- use exec directly to eliminate a level in the process tree
- use "$@" instead of "$*" to pass arguments to openconnect
According to openconnect(8), openconnect will call vpnc-script to
cleanup before quit when it received SIGINT(2) and will quit immediately
when it received SIGTERM (the default signal by kill command)
Before and after the change, openconnect process will be killed first
with SIGINT sent from netifd. This was decided by the
'proto_kill_command "$config" 2' notify call in the proto script.
SIGKILL is the only other signal that can be sent from netifd when the
process did not quit on SIGINT on time. There should be no need to trap
on signal 1 3 6 9 (HUP QUIT ABRT KILL)

If the liblz4 library exists within the build environment, the openconnect
configure will pick it up and start depending on it, leading to the following
build error:
Package openconnect is missing dependencies for the following libraries:
liblz4.so.1
Disable LZ4 support in configure in order to avoid this implicit,
nondeterministic dependency.

Some VPN servers might be configured in a way that a CSD wrapper script
is mandatory to complete the authentication process, allow that to be
specified for openconnect.
