Allow to negotiate the packet command and responses to
whatever values the EC can support.
Set the buffer size including the necessary V3 header.
If the EC run v3 protocol with large packet support, but the kernel
does not have v3 support (3.10), we can not support sending or
receiving large commands.
Be aware that on 3.10, commands like ectool console will fail if
the EC wants to send command larger than the kernel can handle.
Copied kernel_version_ge from libusb-1.0.19/libusb/os/linux_usbfs.c.

TEST=Build a special firmware to exchange 300 bytes.
Check ectool console works with the righ size.
Check that ectool is calling uname.
Check on Nyan_big: without change, "ectool version" crashes kernel. With
changes, "ectool version" works.
In conseuqence, it reverts commit be0bd9b83538427cc350ad38d64b821dfcad82a0,
"ectool: Do not increase buffer size after probe max size from ec"

The ioctl return status for CROS_EC_DEV_IOCXCMD is inconsistent across
kernel versions:
- In 3.8 kernel, on INVALID_VERSION EC result, -EBADMSG is returned
- In 3.14 kernel, on INVALID_VERSION EC result, success status is
returned
In both cases, the INVALID_VERSION result is written to the
cros_ec_command.result parameter.
The inconsistency here should be fixed with kernel patches. In any case,
there is little harm with trying v0 of GET_VERSIONS on any failure of the v1
command.

We've extended host command range from 8-bit to 16-bit. Extend
EC_CMD_GET_CMD_VERSIONS so that the host may query supported command
versions of the new host commands.

Version 1 of EC_CMD_FLASH_WRITE will use as big a write as possible given
the available command parameter space. Falls back to 64 byte writes on old
platforms.
BUG=chrome-os-partner:20571
BRANCH=none
TEST=Copy burn_my_ec onto a link and run it. Write size should be 64 bytes
for the first half of the update (since the old EC doesn't support ver.1
of the write command) and 240 bytes for the second half of the update.
