To install GSIs on external storage (such as sdcards), gsid needs some
additional privileges:
- proc_cmdline and device-tree access to call ReadDefaultFstab().
This is ultimately used to check whether system's dm-verity has
check_at_most_once enabled, which is disallowed with sdcards.
- vfat read/write access to write files to the sdcard. Note that
adopted sdcards are not supported here.
- read access to the sdcard block device. To enable this without
providing access to vold_block_device, a new sdcard_block_device
label was added. Devices must apply this label appropriately to
enable gsid access.
- FIBMAP access for VFAT filesystems, as they do not support FIEMAP.
This only appears to work by granting SYS_RAWIO.

Each tracing event is listed twice in this file, once in
debugfs and once in tracefs:
genfscon debugfs /tracing/events/sched/sched_switch/
genfscon tracefs /events/sched/sched_switch/
Some of the debugfs entries are missing the required leading
/tracing/ prefix, probably a copy paste error from when they were
added.

fsverity_init is a new shell script that uses mini-keyctl for the actual
key loading. Given the plan to implement keyctl in toybox, we label
mini-keyctl as u:object_r:toolbox_exec:s0.
This gives us two benefits:
- Better compatibility to keyctl(1), which doesn't have "dadd"
- Pave the way to specify key's security labels, since keyctl(1)
doesn't support, and we want to avoid adding incompatible option.
Test: Boot without SELinux denial

This is the type used on super partition block devices.
- On devices launch with DAP, super is already marked
as super_block_device_type.
- On retrofit devices, appropriate block devices must
be marked as super_block_device_type, for example:
typeattribute system_block_device super_block_device_type;

These denials occur on boot when android_get_control_file also
changes from readlink() to realpath(), because realpath() will
lstat() the given path.
Some other domains (fastbootd, update_engine, etc.) also uses
libcutils to write to kernel log, where android_get_control_file()
is invoked, hence getattr is added to them as well.

Previously we dumped the data into dropbox. This improves a couple
things:
- We write into dropbox via the fd, so dropbox doesn't pull from the
incidentd directory anymore.
- There is a new API to for priv apps to explicitly read incident
reports. That gives incidentd finer grained control over who can
read it (specifically, it only allows apps to access the incident
reports they requested, or were requested for them via statsd,
instead of getting DUMP and reading whatever they want from
dropbox).

root cause: DocumentsUI provides ArchiveProvider to browse the entries
in archive files by using StorageManager.openProxyFileDescriptor.
i.e. the file descriptor comes from the archive entries is belong to
the void fd. The file descriptor is used by mediaserver but
mediaserver doesn't have the permission to use the file descriptor.

No semantic changes. Just trying to make this easier to understand:
- Separate out common bundles of services from individual services
(the naming doesn't make this obvious).
- Comment the common ones.
- Put related binder_call and service_manager:find rules together.
