[PATCH v13 0/1] MR8467: conhost: Implement F1 and F3 support for history retrieval.

[Joe Souza (＠JoeS209)]

F1 and F3 allow partial retrieval of previous entry from console history.  They are used as shortcuts such that if the following were entered at the command line:

```
md tmptmp
cd <F3>
```

F3 will retrieve the previous line from history past the cursor position, and be auto-completed to "cd tmptmp".  F1 works in a similar fashion, but with one character at a time.
