[arm-allstar] rxondelay negative values --was: Internet drop cos hold

[David McGough]

Hi David,

rxondelay can have both positive and negative values.  Each increment of 
the rxondelay setting represents an additional 20 millisecond delay.  So, 
for example, if you set rxondelay=10, that's 200mS of delay.

If you use a positive value for rxondelay, COS as seen by simpleusb
is always delayed by the set number of milliseconds.

As of mid 2018, rxondelay could also be set to negative values. If set to 
a negative value (e.g.: rxondelay=-10), the rxondelay operation only gets 
applied immediately after the simpleusb PTT was asserted, but not when the 
radio/repeater has been sitting idle.  This improved the problem where 
rxondelay is getting used to solve ping-pong situations.  Since no 
ping-pong occurs when the system is idle, negative values fix the 
problem with user's audio getting chopped off on their initial 
transmissions.

Note that the rxondelay parameter is only applicable to radios attached to 
HamVoIP via the simpleusb driver.
