(Linux only for now) With fastboot reading serial numbers from sysfs, it had
become possible for a fastboot command issued immediately after rebooting
the bootloader to fail, because sysfs still thought the device was online.
To prevent this, after reboot-bootloader we wait for the device to disconnect.
Also made usb_read and usb_write fail immediately if the descriptor has been
closed; this prevents an incorrect error message ("Bad file descriptor")
when errors from fb_getvar are ignored (e.g., by fb_format_supported).
Also removed unused fd param from filter_usb_device, and simplified logic
in usb_write by using do/while instead of a special case for len == 0.

Instead of sending control requests to all devices to read their serial
numbers, read the cached strings from sysfs. This fixes two problems:
1) The control requests sometimes timed out, causing devices to show up
as "????????????????", and 2) a control request could mess up devices
which were in the middle of being flashed.
Also enumerate by walking sysfs rather than devs so that we can avoid
opening host controller devices, which can be slow. On a system with 10
EHCI controllers, fastboot devices now takes 7 msec instead of 700 msec.

Without the partition name, the bootloader would have to store all
of the data until the next flash command, which potentially wastes
time.
To help the bootloader deal with the data more efficiently, we now
issue a flashing hint ("preflash:%s", partname).
"preflash:" is used to indicate that the following download
should ignore any previous "preflash:%s".

Some devices use mkbootimg with weird args for which fastboot
only a hardcoded value.
Now fastboot recognizes those args.

fastboot_protocol.txt used to live in bootable/bootloader/legacy
which was old, obsolete code. However, fastboot_protocol.txt is
a useful file and belongs with the fastboot code.

libext4_utils on host is now called libext4_utils_host so there is no name conflict

Change the default sparse limit to disabled to prevent resparsing files
unless the bootloader or user specifies a sparse limit. Some
bootloaders issue an erase before every flash command, which causes
earlier parts of the downloaded image to get erased.

Add support to fastboot for automatically using libsparse to break large
files, whether they are in sparse or normal format, into multiple sparse
files that can each fit into the target's memory. Allows flashing
images that are larger than the size of the available memory on the
target.
By default, any file over 512MB will be sparsed into 512MB chunks. The
limit can be modified with the -m argument, or sparsing can be forced
with -S or avoided with -N. If -m is not specified, the target can
override the default by implementing getvar:max-download-size

Modify the fastboot argument parsing to use getopt_long. This
simplifies argument parsing, and permutes all the commands to the end of
argv to allow parsing them later.
Also moves usb initailization between argument and command processing,
to allow commands to query parameters over usb.

For manufacturing and testing, there is a need to talk to
whatever device is connected to a given port on the host. This
change modifies fastboot's "-s" option to take either a serial
number or a device path. The device paths of the connected
devices can be listed using "fastboot -l devices" whose output
will resemble:
016B75D60A00600D usb:2-5 fastboot
AD3C12020173 usb:1-4.3 fastboot
The second column lists the device paths. If the -l option is
not given, the output from "fastboot devices" will be the same as
it used to be (i.e. the paths will not be printed).
Finally, note that the format of the device paths are platform
dependent. The example above is from Linux. On OS-X, the paths
will be "usb:" followed by hex digits. For Windows, the device
paths will be printed as "????????????" and the -s option will
not be able to select a device until someone implements the
underlying functionality in usb_windows.c.

Some devices will fail to return the requested data if the final
URB len of the request to > 255.
So shrink the current data buffer from 128 to 127 in the acse of getting
the serial number seems to work just fine.
