(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.

The version of MINGW we compile with has more advanced POSIX support.
Removing legacy MINGW workarounds as those are not needed anymore.

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".

The removal of extra headers from ext4_utils.h removed an indirect

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

If the bootloader doesn't support formatting of those partitions
(either because it doesn't support the getvar commands needed or
the partition type is not supported), the errors are printed but
doesn't halt processing of subsequent commands.

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.

There were some changes to make_ext4fs to add SELinux context. Also, we
changed the "android" argument to an fs_config_func that allows you to
customize the permissions put into a ext4 filesystem.

Some filesystems (e.g. ext4) require flushing an initial
fs image, right after erasing it the partition is unusable.
Doing erase,flush emptyfs is a little bit scaring so we have a
separate command that performs it as atomic step:
- get size of partition
- create an empty filesystem image
- erase the partition
- flush empty fs to the partition
This command applicable only for ext4 filesystem and checks the
partition type before formatting it.

This is needed for products like xoom-cdma and xoom-cdma-lte.
The xoom-cdma-lte product requires an lte baseband binary but
it's not needed for xoom-cdma.
This is implemented by allowing an optional product parameter
to "required" statements. The parameter is separated from
"required" by a colon so the version-baseband-2 requirment in
board-info.txt for stingray becomes:
require-for-product:xoom-cdma-lte version-baseband-2=ltedc_u_03.25.00|ltedc_u_03.19.00
In the above statement, only xoom-cdma-lte requires version-baseband-2
and the baseband can be lte_u_03.25.00 or lte_u_03.19.00. For other
products version-baseband-2 will be ignored.

When using fastboot in scripts, it currently is necessary to parse the
output for FAILED messages and possible other indications of
error. This happens relatively often, for example when there are radio
update issues. Fortunately, fb_execute_queue already has a notion that
an error has occured which is used to abort the queue execution.
This change makes the status value be returned from fb_execute_queue
to main which can then return it as an exit status. usage cases were
also changed to return 1.
Note the code already returned 1 for error in one other case when
there was a problem with boot, so there is a precedent for return 1 on
error in this program.
