Current implementation executes key notify function in TimerHandler
at TPL_NOTIFY. The code change is to make key notify function
executed at TPL_CALLBACK to reduce the time occupied at TPL_NOTIFY.
The code will signal KeyNotify process event if the key pressed
matches any key registered and insert the KeyData to the EFI Key
queue for notify, then the KeyNotify process handler will invoke
key notify functions at TPL_CALLBACK.

For TtyTerm terminals, output a shorter escape sequence when possible
to move the cursor within the current line, and don't print any escape
sequence if the cursor is already at the correct position. This
removes extra cursor motion activity at the EFI shell prompt,
improving performance. It also makes it possible in many cases to
successfully use a terminal window which is taller than the driver's
mode setting (eg. 80x25.)

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.

This patch a adds new terminal type, TtyTerm, to TerminalDxe. This terminal
type provides a place to add support for various *nix terminals that don't
behave like standard VT terminals. The goal is to 'just work' with as many
terminals as possible, rather than properly emulating any one specific
terminal.
