Add support for "dialing" into a PPP server provided by the ESP SDK to provide internet access.
I've tested against Linux pppd on a recent Arch Linux system and FreePPP 2.6.2 on Mac OS 7.5.5 in BasiliskII using a USB-Serial dongle. Using the built-in "programming" USB-Serial chip seems to have trouble initializing, but I haven't tracked down why.
The PPP to serial code bypasses the flow control code right now and just Serial.write()'s the entire packet from the ppp stack. I think it needs a ring buffer to hold the ppp data so it can be subjected to flow control.
