In some terminal, verified with gtkterm and teraterm, backspace key is
not properly processed. For instance, type 'abc', 3 times of backspace
key press then '123' shows the result of 'abc123' instead of '123'. To
fix this, add a routine to process '\b' character input when using
edit_simple.c instead of edit.c (i.e., without CONFIG_WPA_CLI_EDIT=y).

wpa_supplicant and wpa_cli had already moved to allowing up to 4096 byte
buffer size to be used for control interface commands. This was limited
by the line edit buffer in interactive mode. Increase that limit to
match the other buffers to avoid artificially truncating long commands.
