[zircon][usb-request] Move usb request struct to usb protocol header

usb-request.c is being moved out of the ddk folder and its fucntionality
is either moved into the usb protocol or the usb library. As part of
this effort, this changeset moves the usb_request_t and friends to usb
protocol header.

Test: Build. Tested usb mass storage on vim2

[zircon][ulib] Move usb out of driver ulib

This changeset moves usb.c out of the driver ulib and adds a separate
library for itself. In a later changeset some of the usb-request.c
functionality will move in into this library.

Test: Build. Sanity test of usb on vim2

[zircon][usb] Use usb protocol ops instead of usb-request functions

In a previous changeset, I added protocol ops for the usb request functionality.
The motivation behind the changeset is to move usb-request.c out of ddk
and support the operations in usb protocol instead. This changeset, uses those
protocol ops instead of calling the functions in usb-request.c. In a
later changeset, I will move the usb-request.c out of the ddk folder.

Test: Build. Sanity test on vim2

[zircon][xhci][usb-cdc]Add a delay between requests when TRB Error occurs

When downloading files from the target using some of the usb-c ethernet adapters that use
usb-cdc-ecm driver, the scp loses connection intermittently and will not work until a reboot.
The underlying reason is that the device is not able to match the pace of the requests from
client driver. When this happens, the xhc controller converts the NRDY packets on the bus to
TRB Error. There is no way we can further know what the reason for TRB Error and it can be
other things too. So we do the normal reset deque ptr when we see a TRB Error, but we also
introduce a delay between the requests to slow down the I/O. There is a likely chance that
we might need to increase the delays as the situation arises.

[ethernet] Add support for asynchronous eth tx

queue_tx replaces send as the interface for both synchronous and
asynchronous transmissions. Tx data is now passed using ethmac_netbuf_t
structures. If the driver chooses to hold on to the netbuf until
buffer space is available, it can return ZX_ERR_SHOULD_WAIT from queue_tx
and call the ethmac complete_tx() callback when the netbuf is no longer
needed.

[ddk][usb] Remove USB driver support code from the DDK library

Most of the functionality in ddk/common/usb.c has been moved to the USB protocol.
The remainder (usb_iotxn_alloc() and the USB descriptor iterator support) is now
in libdriver.

Function names remain the same, but now take a usb_protocol_t* instead of a
mx_device_t* as its primary argument.

[udev][usb] Clean up error code usage

Previously most USB errors were being reported as MX_ERR_PEER_CLOSED.
We now return MX_ERR_IO_NOT_PRESENT to indicate that the USB device is no longer attached.
Other possibly recoverable errors are now reported as MX_ERR_IO.
Attempting to use a disabled endpoint now returns MX_ERR_BAD_STATE.
We continue to use MX_ERR_IO_REFUSED to report stalled endpoints.

[ddk] new protocol support (1 of n)

This is the start of migration of device protocols from an vtable
structure to a structure with the vtable (ops) and context pointer
(ctx). These will look like:

typedef struct {
protocol_xyz_ops_t* ops;
void* ctx;
} protocol_xyz_t;

The new device_get_protocol(...) fills out a structure of that
style. The legacy device_op_get_protocol() works as before.
Once we've migrated all protocols, providers or protocols, and
consumers of protocols to the new style, we'll remove the legacy
interface.

The device hook get_protocol() is not used by any devices, so we
will convert it to the new style API now.

It's no longer possible to get the DEVICE protocol because that's
private between the devhost and the device and should not be
accessible to arbitrary clients. Nothing depends on this.

This also converts MX_PROTOCOL_ETHERMAC and WLANMAC to the new
style and updates the DDKTL's wrappers of device, ethermac, etc.
