hfpmodem: Fix release-and-swap without +CIEV
Some phones do not send the corresponding call state update (+CIEV)
after a successful release-and-swap operation (AT+CHLD=1).
This has been observed with a Nokia 500, while testing ReleaseAndSwap()
while an active and a held call exist:
ofonod[20414]: > AT+CLCC\r
ofonod[20414]: < \r\n+CLCC: 1,0,1,0,0,"<number1>",145\r\n
ofonod[20414]: < \r\n+CLCC: 2,0,0,0,0,"<number2>",145\r\n
ofonod[20414]: < \r\nOK\r\n
ofonod[20414]: > AT+CHLD=1\r
ofonod[20414]: < \r\nOK\r\n
After this, no +CIEV is received, but the call has been hung up.
The proposed approach to solve this consists of using AT+CLCC, unless
a call release has been received within a specific time period.
The result fixes the problem as can be seen below:
ofonod[20847]: < \r\n+CLCC: 1,0,1,0,0,"<number1>",145\r\n
ofonod[20847]: < \r\n+CLCC: 2,0,0,0,0,"<number2>",145\r\n
ofonod[20847]: < \r\nOK\r\n
ofonod[20847]: > AT+CHLD=1\r
ofonod[20847]: < \r\nOK\r\n
ofonod[20847]: > AT+CLCC\r
ofonod[20847]: < \r\n+CLCC: 1,0,0,0,0,"<number1>",145\r\n
ofonod[20847]: < \r\nOK\r\n
ofonod[20847]: < \r\n+CIEV: 5,2\r\n
ofonod[20847]: < \r\n+CIEV: 5,0\r\n

hfpmodem: Avoid transitional voicecall states
While processing the result of AT+CLCC, process the differences in a way
that disconnections are reported first, then call state changes and
finally new calls.
The goal is to avoid unnecessary transitional states such as two active
calls existing at the same time.
