1c308bbbf5 dropbear: add option to set receive window size
The default receive window size in dropbear is hardcoded to 24576 byte
to limit memory usage. This value was chosen for 100Mbps networks, and
limits the throughput of scp on faster networks. It also severely limits
scp throughput on high-latency links.

Add an option to set the receive window size so that people can improve
performance without having to recompile dropbear.

Setting the window size to the highest value supported by dropbear
improves throughput from my build machine to an APU2 on the same LAN
from 7MB/s to 7.9MB/s, and to an APU2 over a link with ~65ms latency
from 320KB/s to 7.5MB/s.

6371159b4a dropbear: add option to set max auth tries
Add a uci option to set the new max auth tries paramater in dropbear.
Set the default to 3, as 10 seems excessive.

e5bbead1a8 dropbear: fix procd interface trigger install
Install procd interface triggers only for interfaces which are enabled
so dropbear instances running on (an) enabled interface(s) are not
restarted due to an interface trigger of an interface which is disabled.

16122117a5 dropbear: Add procd interface triggers when interface config is specified
A dropbear instance having an interface config won't start if the interface is down as no
IP address is available.
Adding interface triggers for each configured interface executing the dropbear reload script
will start the dropbear instance when the interface is up.

20940138ac scripts: fix wrong usage of '==' operator
[base-files] shell-scripting: fix wrong usage of '==' operator

normally the '==' is used for invoking a regex parser and is a bashism.
all of the fixes just want to compare a string. the used busybox-ash
will silently "ignore" this mistake, but make it portable/clean at least.

this patch does not change the behavior/logic of the scripts.

b2d099c11c dropbear: ensure the interface has an ip-address
Use network_get_ipaddrs_all to get all ip-addresses of an interface. If the
function fails, the interface does not exists or has not any suiteable ip
addresses assigned.

Use the returned ip-address(es) to construct the dropbear listen address.

2ae05c57f8 package/*: remove useless explicit set of function returncode
somebody started to set a function returncode in the validation
stuff and everybody copies it, e.g.

myfunction()
{
	fire_command

	return $?
}

a function automatically returns with the last returncode,
so we can safely remove the command 'return $?'. reference:

http://tldp.org/LDP/abs/html/exit-status.html
"The last command executed in the function or script determines the exit status."

f2fdd8ebdb dropbear: add options SSHKeepAlive and IdleTimeout.
Without timeout mechanism, if ssh client disconnected without sending
FIN or RST, forked dropbear servers would hang there for
KEX_RETRY_TIMEOUT seconds (8 hours).

TCP keepalive is not implemented in dropbear yet, thus the name
SSHKeepAlive.

300 seconds in this patch is selected from the default value of
ServerAliveInterval for Debian ssh client (See man ssh_config).
