Handle UPDATE_EXTRA_CMD_PAIR_CHALLENGE command, where the
lid sends a random x25519 public key, and nonce, and the base
replies with its own (stable) x25519 public key, and computes
a shared secret using its private key to verify its identity.

TEST=Flash hammer, ./usb_updater2 -c always reports the same
device public key, and authenticator is correct.

Previously the GPIO driver used quite redundant encodings for its WUI
and DEVALT mapping tables. This refactor compresses those tables
significantly, while adding the ability to represent an inverted DEVALT
bit. The resulting RO firmware image for Wheatley is 384 bytes smaller.
This commit also corrects the interpretation of the func parameter to
gpio_set_alternate_function. Any non-negative func should be
interpreted as a request to switch a pin to an alternate mode.

This patch introduces HOST_CPPFLAGS to be used for all
objects being compiled with HOSTCC rather then the target
compiler.
Since glibc is not linked into the EC, no glibc include files
should be included in the EC code base. Hence, create local
definitions for clock_t and wchar_t that match what the glibc
include would have done, and remove some unneeded includes.
Due to very eager optimization, we have to give gcc a little
notch to not kick out memset.

This unifies all the EC header files to use __CROS_EC_FILENAME_H
as the include guard. Well, except for test/ util/ and extra/
which use __TEST_ __UTIL_ and __EXTRA_ prefixes respectively.

This will let us check the size of static array initializers.
Also moved this macro definition and ARRAY_SIZE into a new "tricks.h"
header, so that userspace utils can use it too.
