c007c43335 fs_mgr.cpp: fix the problem that the casefold feature not enabled for the data partition 
The value of entry.mount_point for data partition is "/data"

Fixes: 5ba5b90cd6 ("fs_mgr: try tune2fs for casefolding on /data only")

Test: got "Can't mount with encoding and encryption" problem reported
      by the db845c build with the default 5.4.38 prebuilt kernel

fe7585a8b0 snapuserd: Refactor client to allow persistent connections. 
This refactors SnapuserdClient so it retains a connection for its
lifetime. This allows SnapshotManager to ensure the daemon is running
and hold a connection open across all of its operations.

The main impetus of this change is to remove the ambiguity between first
and second-stage sockets. SnapshotManager should only ever connect to
the first-stage socket during first-stage init, or, to initiate the
"transition" step during second-stage init.

The transition steps are roughly:
 (1) Start second-stage daemon.
 (2) Load new device-mapper tables.
 (3) Connect second-stage daemon to new dm-user devices.
 (4) Activate the new tables, flushing IO to the first-stage daemon.
 (5) Send a signal to the first-stage daemon to exit.

This patch makes it easier to hold these two separate connections.

cff35f67ad snapuserd: Refactor daemon/server. 
This is in preparation for moving to a traditional client/server model
where clients stay connected and the server multiplexes multiple
connections.

Client has been renamed to DmUserClient to differentiate it from local
socket clients.

poll() responsibilities have been moved into SnapuserdServer. In
addition, the server now tracks all open clients and polls them
together with the listen socket.

SnapuserDaemon is now only responsible for signal masking. These two
classes can probably be merged together - I didn't do that here because
the patch was already large.

3d17cb9a57 Add GetLastLabel and InitializeAppend 
GetLastLabel returns the last Label that a reader is confident about.
InitializeAppend starts a writer up to append data after the last given
label, assuming all later labels are not relevant data.

2d2fd72502 Switch up Cow Format to be resumable 
This switches up the format to alternate ops with data, followed by a
footer containing additional meta information. This allows the file to
be resumed at arbitrary points if writing gets interrupted by power
loss.
Also adds a label op, which allows labeling future ops as connected.
If the footer is missing, Append will treat the last label as possibly
corrupt, and ignore it.

253289fe07 Introduce security.lower_kptr_restrict property 
This is to allow the tracing service to temporarily
lower kptr_restrict for the time it takes to build
its internal symbolization map (~200ms), only on
userdebug/eng builds.
kptr_restrict unfortunately cannot be lowered by
the tracing service itself. The main reason for that
is the fact that the kernel enforces a CAP_SYS_ADMIN
capability check at write() time, so the usual pattern
of opening the file in init and passing the FD to the
service won't work.

For more details see the design doc go/perfetto-kallsyms.

b4a81ccd5a reland: Rename Flush to Finalize 
As we change to a more resumable format, flush mostly writes the final
parts of the file that are needed, which would write extra data that is
not needed to continue writing, and would immediately be overwritten.

Additionally, in the next patch we will fsync the file after adding an
op, making the flush built in, and the Finalize name more appropriate.
