3a8768804c Fix handle_opendir() in the sdcard daemon
The fuse_open_out structure returned to the kernel by handle_opendir()
was not properly initializing all the fields.  The symptom was recursive
ls (ls -R) failing on the emulated sdcard filesystem, because rewinddir(3)
was failing with ESPIPE.

977a9f3b1a Add legacy layout support to FUSE, enforce write.
The legacy internal layout places users at the top-level of the
filesystem, so handle with new PERM_LEGACY_PRE_ROOT when requested.

Mirror single OBB directory between all users without requiring fancy
bind mounts by letting a nodes graft in another part of the
underlying tree.

Move to everything having "sdcard_r" GID by default, and verify that
calling apps hold "sdcard_rw" when performing mutations. Determines
app group membership from new packages.list column.

Flag to optionally enable sdcard_pics/sdcard_av permissions
splitting. Flag to supply a default GID for all files. Ignore
attempts to access security sensitive files. Fix run-as to check for
new "package_info" GID.

a4b4e9ad8e Parse IP address changes in NetlinkEvent.
This adds support for parsing RTM_NEWADDR and RTM_DELADDR
netlink messages received on netd's netlink socket and
formatting them them so NetlinkHandler can process them.

Address changes are notified in subsystem "address". Interface
changes, which used to be notified in subsystem "net", are now
notified in subsystem "interface" to avoid confusion.

dfe0cbab3f Richer SD card permissions through FUSE.
Changes the FUSE daemon to synthesize an Android-specific set of
filesystem permissions, even when the underlying media storage is
permissionless.  This is designed to support several features:

First, apps can access their own files in /Android/data/com.example/
without requiring any external storage permissions.  This is enabled
by allowing o+x on parent directories, and assigning the UID owner
based on the directory name (package name).  The mapping from package
to appId is parsed from packages.list, which is updated when apps are
added/removed.  Changes are observed through inotify.  It creates
missing package name directories when requested and valid.

Second, support for separate permissions for photos and audio/video
content on the device through new GIDs which are assigned based on
top-level directory names.

Finally, support for multi-user separation on the same physical media
through new /Android/user/ directory, which will be bind-mounted
into place.  It recursively applies the above rules to each secondary
user.

rwxrwx--x root:sdcard_rw     /
rwxrwx--- root:sdcard_pics   /Pictures
rwxrwx--- root:sdcard_av     /Music

rwxrwx--x root:sdcard_rw     /Android
rwxrwx--x root:sdcard_rw     /Android/data
rwxrwx--- u0_a12:sdcard_rw   /Android/data/com.example
rwxrwx--x root:sdcard_rw     /Android/obb/
rwxrwx--- u0_a12:sdcard_rw   /Android/obb/com.example

rwxrwx--- root:sdcard_all    /Android/user
rwxrwx--x root:sdcard_rw     /Android/user/10
rwxrwx--- u10_a12:sdcard_rw  /Android/user/10/Android/data/com.example

These derived permissions are disabled by default.  Switched option
parsing to getopt().

3ad3d1c4b5 Add basic verity support to fs_mgr.
This change adds a "verify" fs_mgr flag specifying that
the device in question should be verified.

Devices marked with this flag are expected to have a
footer immediately after their data containing all
the information needed to set up a verity instance.

6d611a891d Make Flattenable not virtual (libutils)
Making an object Flattenable doesn't force it to
become virtual anymore. For instance, Fence and GraphicBuffer
are now non-virtual classes.

Also change Flatennable protocol a bit so that it updates
its parameters (pointers, sizes) to make it easier
to implement a flattenable in terms of other flattenables.

4485d0d966 new String8, String16 ctors to initialize empty static strings with static linkage
when libutils is statically linked, the ordering of the static
initializer is not guaranteed and therefore it's unsafe to use
empty static strings: e.g.:

static String8 sThisStaticStringIsNotSafe;

instead, this new constructor can be used:

static String8 sThisStaticStringIsSafe(kEmptyString);

6cd548c715 Fix a crasher with RefBase debugging and vectors of wp<>
background:
we have some code to fix-up the IDs of references when
using RefBase's DEBUG_REFS when those refs are managed by
arrays wp<> or sp<> (this is because wp<> / sp<> don't have
a trivial ctor when DEBUG_REFS is enabled, and Vector
treats them as trivial for obvious performance reasons)

this is complicated by the fact that we don't want to have
to recompile everything when enabling DEBUG_REFs (i.e.: the
Vector code cannot know wheter it's enabled or not for its
template stuff).

problem:
there was a bug in the fix-up code for wp<> which was trying
to access the weakref_impl from the RefBase* however, this was
moronic since RefBase could have been destroyed if there wasn't
any more strong refs -- and this happned. Instead we need to get
the weakref_impl directly from the wp<>

6d4419d9b1 A few tweaks to RefBase debugging
- stacks are now saved in /data/debug which must be
  created and writable by the user.

- removed "always fatal" DEBUG_REFS option, it wasn't
  really needed.

- DEBUG_REFS_ENABLED_BY_DEFAULT is not the default anymore
  (usually people want to target which refs they're tracking)
