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.

Until ext4_utils switches to using libsparse, libext4_utils defines some
of the same symbols as libsparse. Fastboot links statically against
both of them, and there is no easy way to make the symbols hidden, so
just rename them in libsparse.

Add sparse_file_len, which will compute the size of data that would
be produced if sparse_file_write was called. Useful combined with
sparse_file_callback.
Change-Id: I1a156d1071760f5559483954a5c62ffc20298703
Add sparse_file_repsarse, which splits chunks in an existing sparse
file such that the maximum size of a chunk, plus a header and footer,
is smaller than the given size. This will allow multiple smaller
sparse files to result in the same data as a large sparse file.
Change-Id: I177abdb958a23d5afd394ff265c5b0c6a3ff22fa
Add a new output file subclass that will call a callback for
each block as it is written. Will be used to measure the space
used by each sparse block to allow resparsing files.
Also add sparse_file_callback, which will write out a sparse
file by calling the provided write function.

Create two subclasses of output_file that can handle normal
and gzipped files, and refactor open_output_fd. Will allow
adding support for an output_file type that is not file
backed.

Abstract the logic from simg2img into libsparse, and add logic
for reading a regular image into libsparse. simg2img then
becomes a simple wrapper around libsparse.
img2simg was not actually making the file sparse, it was using
sparse files to create multiple files that could be pieced back
together. Replace it with a simple wrapper around libsparse.
Its functionality will be replaced by an simg2simg that can
resparse a file into smaller chunks.

When a block is added that is adjacent to another block and of the same
type, merge it. This will be useful for converting regular images to
sparse images, allowing the reader to add a single block at a time and
letting libsparse optimize into larger blocks as it goes.
Does not support merge two blocks that are backed by a data pointer,
only blocks that are backed by a file for now.

Add sparse_file_add_fd to include all or part of the contents
of an fd in the output file. Will be useful for re-sparsing files
where fd will point to the input sparse file.

Move block loops into sparse.c with iterator helpers in backed_block.c.
Simplify chunk writing by moving skip chunk calls from output_file.c to
sparse.c.
Rename variables to be consistent with new naming.
Remove use of u8, u32, u64.
Change-Id: Ic138ad58bef9f96239266ccee12ee83ea285e7eb
Removes static variables in backed_block.c to allow multiple
sparse files to be open at the same time.

This moves an exact copy of libsparse from
system/extras/ext4_utils/libsparse to system/core/libsparse in
preparation for linking tools in system/core against it.

The code is from NetBSD, with the -n and -h options removed to make
porting easy. Also, removed support for the BLOCKSIZE environment
variable for the same reason.

Declare audio_devices_t as uint32_t to permit bit operations,
and a separate anonymous enum for the constants. This is similar to
audio_channel_mask_t.
Also remove spurious "typedef" on declaration of anonymous enum for
channel mask constants.

Also add ion_alloc_fd helper for when you only want a filedescriptor
and know you won't need to access this handle again by its ion_handle

When creating a new file using open(..., O_CREAT), it is an error
to fail to specify a creation mode. If a mode is not specified, a
random stack provided value is used as the "mode".
This will become a runtime error in a future version of Android.

Code using ifc_reset_connections api needs to have access to
predefined masks for reset_mask parameter

This change deprecates the existing queueBuffer, dequeueBuffer, lockBuffer, and
cancelBuffer functions, and replaces them with a queueBuffer, dequeueBuffer,
and cancelBuffer function that accepts or returns a libsync fence file
descriptor. It also adds the native_window_dequeue_buffer_and_wait convenience
function.

This change removes the #includes of "linux/*.h" headers from the libsync
header. It currently does this by copying the needed structs that are in the
linux headers. This is intended to be a temporary solution.

"/sbin/watchdogd <interval> <margin>" will open /dev/watchdog, try

Wait for the early suspend transition to finish to the point where
surfaceflinger would previously have synchronized. This is important
during screen on, to ensure the display early suspend handlers have
completed before surfaceflinger unblanks.

This format describes buffers that are not structured like normal
image data, and can only be meaningfully understood by the endpoints.
As an example, this format is used for transporting JPEG-compressed
image buffers from the Camera HAL to the framework/apps.
Buffers of this format must have a height of 1 and a width equal to
their size in bytes. Otherwise their interpretation is up to the two
endpoints.
