This reverts commit 31ae446b1a.
Changing the receive FIFO depth in Terminal driver Start() is not
recommended.
A new PCD PcdUartDefaultReceiveFifoDepth was added and
MdeModulePkg/SerialDxe driver uses the PCD as the default receive
FIFO depth.

The Serial IO protocol instances provided by SerialDxe and consumed by
TerminalDxe come with a Mode.ReceiveFifoDepth=1 default setting, as
required by UEFI 2.5.
Although TerminalDxe calls EFI_SERIAL_IO_PROTOCOL.SetAttributes() in the
TerminalDriverBindingStart() and TerminalConInTimerHandler() functions, it
only does so to change the Mode.Timeout member. Other members of Mode,
including Mode.ReceiveFifoDepth, are preserved.
On some platforms this causes the UART that underlies TerminalDxe not to
have enough room for bursts of scan codes, which translates to broken
parsing of escape sequences, e.g. cursor movement keys.
According to the UEFI spec, passing ReceiveFifoDepth=0 to
EFI_SERIAL_IO_PROTOCOL.SetAttributes() "will use the device's default FIFO
depth". While TerminalDxe could try to configure a receive FIFO depth that
matches the longest escape sequence it wishes to parse, in practice the
device-specific default FIFO depth -- which may well differ from the
spec-mandated SerialIo->Mode.ReceiveFifoDepth=1 default -- seems to work.
Hence let's just set that.
This issue was exposed by SVN r18971 / git commit 921e987b2b
("ArmPlatformPkg: Use SerialDxe in MdeModulePkg instead of EmbeddedPkg").
In that conversion, MdeModulePkg's SerialDxe started to initialize
Mode.ReceiveFifoDepth to 1 (in conformance with the spec), unlike the
prior, non-conformant initialization to 0 in EmbeddedPkg's SerialDxe.
Since TerminalDxe would never change ReceiveFifoDepth from the new default
value 1, and the ArmPlatformPkg/Drivers/PL011Uart library instance,
underlying SerialDxe through SerialPortLib, would obey it too, they would
collectively effect a receive queue depth of 1, rather than the default 16
or 32. This broke cursor keys on the ARM FVP and Juno platforms.
It is the client of EFI_SERIAL_IO_PROTOCOL that is responsible for
modifying the attributes, if the defaults are not appropriate, hence this
patch modifies TerminalDxe.

The SerialIo->GetControl() function is not required to set the
Control output parameter on error. Make sure we apply the
EFI_SERIAL_INPUT_BUFFER_EMPTY optimization in
TerminalConInTimerHandler() only if the SerialIo->GetControl()
function call set that bit in the Control variable.

1. Get default terminal type from PCD rather than using PCANSI
directly in BuildTeminalDevpath;
2. Only terminal type is needed to create an TerminalDev instance, so
remove the useless code of creating and freeing DefaultNode.

Accept the VT220 escape code [3~ as backspace for TtyTerm terminals. This is
sent by many Linux terminals by default. Also accept VT220 function keys
F1-F12, and VT100 F1-F4 keys as these are commonly sent by Linux terminals.
The VT220 escape codes are longer, and variable length so a new state is added
to the state machine along with a variable to construct the multibyte escape
sequence.
There are currently no ambiguous escape sequence prefixes accepted, so the TTY
terminal accepts escape sequences for a variety of terminals. The goal is to
'just work' with as many terminals as possible, rather than properly emulating
any specific terminal. Backspace, Del, and F10 have been tested on xterm,
rxvt, tmux, and screen.
Note: The existing vt100 function key handling does not match the vt100
documentation that I found, so I added the TTY terminal handling
of VT100 F1-F4 (really PF1-PF4 on vt100) separately. The vt100
has no F5-F10 keys, so I don't know what the current vt100 code
is based on.
