This speeds up memcpy by copying a word at a time if source and destination are
aligned in mod 4. That is, if n and m are a positive integer:
4n -> 4m: aligned, 4x speed.
4n -> 4m+1: misaligned.
4n+1 -> 4m+1: aligned in mod 4, 4x speed.
Ran the unit test on Peppy:
> runtest

Running test_memcpy... (speed gain: 120300 -> 38103 us) OK

Ran make buildall -j:

Running test_memcpy... (speed gain: 2084 -> 549 us) OK

Note misaligned case is also optimized. Unit test runs in 298 us on Peppy while
it takes about 475 with the original memcpy.

This make minor syntactic changes and renames some camel-cased symbols

We often need to watch for transitions between one state and another, so
that we can issue warnings or take action ONCE. This abstracts that "have I
already reacted to this" stuff into a single set of functions.
For example, this code reads a GPIO every time through the loop, but it only
generates an event when the GPIO value changes from 0 to 1:
cond_t c;
cond_init_false(&c);
while(1) {
int val = read_some_gpio();
cond_set(&c, val);
if (cond_went_true(&c))
host_event(SOMETHING_HAPPENED);
sleep(1);
}

Keys I keep hitting should work like I expect them to.
Home or Ctrl+A = move to beginning of line
End or Ctrl+E = move to end of line
Del = delete-right
Ctrl+K = delete to end of line
Ctrl+L = clear screen and reprint current line
Ctrl+N = next command
Ctrl+P = previous command
Also, improve filtering of escape sequences and non-printable
characters, so hitting unsupported keys or control codes doesn't mess
up the current line of input.

The EC console input handling code is being enhanced to accept
abbreviated command names.
If the abbreviation is unique, the appropriate command is used, if the
abbreviation is ambiguous, the command is handled as nonexistent. The
error message is being modified to mention that the command either
does not exist or is ambiguous.
This change also makes it impossible to have command names matching
the beginning of other command names. Two such cases are being fixed
(`ch' renamed to `chan' and `thermal' renamed to 'thermalconf').
