When host fastboot sends sparse blocks to the device, it tries to only
send blocks in multiples of 1024 bytes. If a block is not aligned to this
size, the excess bytes are prepended to the next write operation. This
is implemented by doing the write in two steps: first the previous
excess from the last write (plus new data up to alignment), then a
second write for the aligned remainder of the new data.
This logic has a bug if the final block plus the previous excess data
contains >= 1024 but < 2048 bytes. In this case the first write will
drain 1024 bytes from the data, and the second write will not have 1024
bytes to write. Instead of retaining this data for the next write, it
tries to write 0 chunks (and thus 0 bytes), which hangs the ioctl() call.

For testing there needs to be a way to simulate unplugging and
replugging a device. This change adds support for a USB reset
method that does this.
Also add timeouts, so USB reads/writes don't block forever
on an unresponsive device.
Test: glinux, fastboot tool still works
Test: Reset confirmed working via wireshark Linux URB captures

This change creates a nice and clean API for issuing
fastboot commands without using the fastboot tool itself.

Test: flash radio radio.img

Builtin command "type" in zsh doesn't support -t option and this
is resolved by checking the shell type prior to sourcing them.
Instead of using "type -t" explicitly, check_type() knows the the
type of the current shell and behaves accordingly.

MinGW uses gnu_printf to force C99 printf analysis with GCC, but clang
does not support gnu_printf. So just use the default that's used for
other platforms. This also mirrors upstream commit
015e637b4b/.
Test: m native-host-cross with Clang.

Check that the value fits in uint32_t that's supported by the current
protocol.
Also fix and sanity check the max_size before passing it to
sparse_file_resparse(), which accepts `unsigned int`. This shouldn't
happen in practice because of RESPARSE_LIMIT (1 GiB).
Test: `fastboot flash` with small and large images.

The header version argument is meant for creation of boot images
using boot and flash:raw commands. It is unnecessary to specify the same

We've got an internal target 'static_sdk_tools' that attempts to ensure
that both adb and fastboot are distributed as artifacts. It's
essentially a loop calling dist-for-goals on
$(HOST_OUT_EXECUTABLES)/{adb,fastboot}.
The dist-for-goals macro has de-duplication checks, but both the src and
dest needs to be identical. Currently adb is using the installed
executable, fastboot is using the built executable, and static_sdk_tools
is trying to use the installed versions of both.
This causes an overriding commands for target warning, which I recently
turned into a warning.
Maybe everything should be converted over to using the built
executables, but that requires a bunch more checks everywhere, and most
places are already using the installed version.
