When using a third party screen capture program called androidscreencast
(http://code.google.com/p/androidscreencast/) to get the framebuffer of
the device, there are tons of screencap zombie processes got left behind.
The issue is also mentioned here: http://code.google.com/p/android/issues/detail?id=22836.
The cause of the issue is that adbd spawns off screencap processes,
and these child processes were not waited to be finished.
This change fixes the issue.

* changes:
fastboot: add support for auto-resparsing large files
fastboot: add fb_getvar
fastboot: use getopt_long
libsparse: rename symbols that conflict with libext4_utils
libsparse: add sparse_file_len
libsparse: add function to resparse a file and a utility to use it
libsparse: add callback output file type
libsparse: pseudo-subclass output_file for normal and gz files
libsparse: add sparse_file read and convert tools to use it
libsparse: fix windows image writing
libsparse: merge adjacent blocks of the same type
libsparse: add error reporting functions
libsparse: add support for including fds
libsparse: cleanups
libsparse: remove static variables
system/core: move libsparse into system/core
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.
Change-Id: Idc2cfe20efe3c3a7fb8233f453a89bbbeb0dcc8b
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.
Change-Id: I18707bd9c357b68da319cc07982e93d1c2b2bee2
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.
Change-Id: I26744c74d13f205cf17df1ea9caac1eea9c57357
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.
Change-Id: I95aa231714cbe01ac194e868c21385806c0bdb97
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.
Change-Id: I5d4ab07fb37231e8e9c1912f62a2968c8b0a00ef
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.

When running "adb tcpip 5555", adb create a service socket named
"tcpip:5555". Only compare the 6 first chars "tcpip:" to decide if
we enable exit_on_close.

This change adds init.rc steps to:
* allow kernel tracing to be enabled via adb
* allow a limited set of kernel trace events to be enabled via adb
* allow the kernel trace to be read via adb
* allow all users to write to the kernel trace from userland

Provides a new mechanism for dumpstate (while running as root)
to request that debuggerd dump the stacks of native processes that
we care about in bug reports. In this mode, the backtrace
is formatted to look similar to a Dalvik backtrace.
Moved the tombstone generating code into a separate file to
make it easier to maintain.
Fixed a bug where sometimes the stack traces would be incomplete
because we were not waiting for each thread to stop after issuing
PTRACE_ATTACH, only the main thread. So sometimes we were missing
traces for some threads.
Refactored the logging code to prevent accidentally writing data
to logcat when explicitly dumping a tombstone or backtrace from the
console.
Only root or system server can request to dump backtraces but
only root can dump tombstones.

With this change, the audio rr/fifo threads will just run in
the fg cgroup.
Also, the RR budget for the apps fg/bg threads has been bumped
to 80%. Ideally, the bg budget would be much smaller but there
are legacy libraries that seem to be very sensitive to this so
for now keep it at this value.

Adds an apps cgroup which will contain fg tasks. Move the bg group
nested underneath it.
