Always assert DCD and DSR in bhyve's uart emulation.
The /etc/ttys entry for a serial console in FreeBSD/x86 is as follows: ttyu0 "/usr/libexec/getty 3wire" vt100 onifconsole secure
The initial terminal type passed to getty(8) is "3wire" which sets the CLOCAL flag. However reset(1) clears this flag and any programs that try to open the terminal will hang waiting for DCD to be asserted.
Fix this by always asserting DCD and DSR in the emulated uart.
The following discussion on virtualization@ has more details: https://lists.freebsd.org/pipermail/freebsd-virtualization/2015-June/003666.html

Disable the 'uart_drain()' callback when the emulated receive FIFO is full.
Failing to do this will cause the kevent(2) notification to trigger continuously and the bhyve(8) mevent thread will hog the cpu until the characters on the backend tty device are drained.
Also, make the uart backend file descriptor non-blocking to avoid a select(2) before every byte read from that backend.

Open the uart emulation's backing tty in non-blocking mode. This fixes the issue of bhyve appearing to halt when using nmdm ports for the console, until a connection is made to the other end.
bhyveload already does this.

Allow bhyve and bhyveload to attach to tty devices.
bhyveload: introduce the -c <device> parameter to select a tty for output (or "stdio")
bhyve: allow the puc and lpc-com backends to accept a tty in addition to "stdio"
When used in conjunction with the null-modem device, nmdm(4), this allows attach/detach to the guest console and multiple concurrent serial ports. kgdb on a serial port is now functional.

Add support for PCI-to-ISA LPC bridge emulation. If the LPC bus is attached to a virtual machine then we implicitly create COM1 and COM2 ISA devices.
Prior to this change the only way of attaching a COM port to the virtual machine was by presenting it as a PCI device that is mapped at the legacy I/O address 0x3F8 or 0x2F8.
There were some issues with the original approach: - It did not work at all with UEFI because UEFI will reprogram the PCI device BARs and remap the COM1/COM2 ports at non-legacy addresses. - OpenBSD GENERIC kernel does not create a /dev/console because it expects the uart device at the legacy 0x3F8/0x2F8 address to be an ISA device. - It was functional with a FreeBSD guest but caused the console to appear on /dev/ttyu2 which was not intuitive.
The uart emulation is now independent of the bus on which it resides. Thus it is possible to have uart devices on the PCI bus in addition to the legacy COM1/COM2 devices behind the LPC bus.
The command line option to attach ISA COM1/COM2 ports to a virtual machine is "-s <bus>,lpc -l com1,stdio".
The command line option to create a PCI-attached uart device is: "-s <bus>,uart[,stdio]"
The command line option to create PCI-attached COM1/COM2 device is: "-S <bus>,uart[,stdio]". This style of creating COM ports is deprecated.
