* Common duration type for ctap library independent of TockOS
* Implement Env-specific ctap-hid channels for I/O
Common I/O Status, Error and Result types
* Move common user presence checking code to ctap library
* Move CtapHidChannel and UserPresence traits, with their accompanying
types to separate API mods. Remove Default implementations of methods
in these traits, to keep all implementation details inside of concrete
Env types.
Rename methods in UserPresence trait, for better readability.
Remove duplicate code for finding appropriate HID channel for given
transport.
Rework check_user_presence() function so that there's no more need for
quick_check() method in UserPresence trait. To short-circuit user
presence check, Env implementation may use wait_with_timeout() method.
* Fix button press wait with zero timeout for TockEnv
* Fix formatting
* Remove type for duration, use embedded_time::duration::Milliseconds
directly, for better readability.
Treat any unconfirmed result of user presence check as an error, which
maps more naturally to CTAP spec status codes.
Remove unneeded underscores in trait definition.
Store usb endpoint directly, in TockEnv channels, to avoid unneeded
conversions.
* No need for separate error type for send_keepalive_up_needed()
* Document UserPresence trait and types.
Remove unused parameters in UserPresence trait's methods.
Add conversion function from UserPresence errors to Ctap2 status codes.
Do not check button status when tock user presence wait is called with
zero timeout.
* Make test environment always report success sending data
* Rename CtapHidChannel to HidConnection, rename *_hid_channel ->
*_hid_connection, for clarity. Use "Channel" to refer to the logical
connection from authenticator to one client, and use "Connection" to
refer to physical connection of authenticator to platform, on which
clients run.
Remove channel parameter from user presence API, it's not needed.
* Remove duplicate comments.

* Introduce Customization trait
* Introduce Customization trait including the customization accessors
that control various behaviors.
* Expose Customization through a getter API in Env, and make the code
that directly access the constants currently switch to accessing the
customizations via Env.
* TockEnv's customization getter implementation directly returns the
reference of the global DEFAULT_CUSTOMIZATION constant, so the
constant values are still inlined and dead code won't be compiled.
* We'll add the customizations from global constants to the struct
one-by-one, only MAX_MSG_SIZE in this commit.
* Small fixes
* Fix deploy script
* put is_valid under std gate
