We only need a single binder thread to receive notifications, so we
should set the thread pool max to 0 rather than 1. startThreadPool()
starts one thread + the max count.

The Trusty storage proxy requires that the suspend service is started to
acquire a wakelock for UFS RPMB operations. Without the binder thread
pool running, starting this service results in at least a 1s polling
delay. This change ensures that we start the thread pool before handling
any RPMB operations, so acquiring the wakelock will complete as soon as
the service is ready without needing to poll once per second.

Adds a system vendor property (ro.vendor.trusty.storage.fs_ready) to
indicate when backing storage on the Android filesystem (e.g. /data) is
ready for use. Before this property is set, the Trusty storage proxy may
restart causing connections in Trusty to the storage service to be
disconnected. All Trusty operations that may require storage and can
wait until the device filesystems are ready should wait on this
property.

Previously we did not support STORAGE_MSG_FLAG_POST_COMMIT for anything
but RPMB operations (in which case it was a no-op). We need to support
this flag in order to store a superblock in non-secure storage, as we
need that write to commit atomically wrt all other writes.

Switches to syncing the parent directory immediately when creating a new
file rather than lazily waiting for a sync request. Because we only
create a new file when the userdata partition is cleared, this operation
doesn't need to be fast in the normal case. This avoids needing to track
the parent directory for each file for lazy syncing later, since storage
backing files may be in a subdirectory of the root.

Adds a check for a DSU mode boot in storageproxyd. Changes path handling
so that storageproxyd will not allow opening a file in the root data

store its backing file.

If a checkpointing operation is in progress, discard any write operations
that are flagged as STORAGE_MSG_FLAG_PRE_COMMIT_CHECKPOINT. In tandem
with trusty-side changes that set the flag appropriately, this avoids
the awkward case where the checkpoint is rolled back, which potentially
leads to inconsistency between the data and the superblock.
Based on Stephen's CL/1845477 "Add helper to check checkpoint state of
mounts".

Attempts a retry of the intial write or read when an RPMB command
triggers a UNIT ATTENTION condition. This causes the UA status to be
reset and hopefully result in a successful command. This runs the risk
of retrying a successful write, but we wouldn't have been able to get
the RPMB response after that write anyway due to the UA condition.

The UFS support got rebased on top of the RPMB socket support
improperly. As a result, RPMB socket support was broken due to an
unconditional rmpb_fd = rc which would set the rpmb_fd to be connect()'s

When developing, it may be preferable to operate on a device which does
not have a real RPMB storage, or which is unprovisioned. This CL allows
the rpmb_dev program to act as a daemon serving a fixed key, and for
storageproxyd to speak to rpmb_dev's socket rather than an actual rpmb
device or a virtual rpmb device.

In order to test Trusty gatekeeper automatically, the storage proxy
needs to be active inside the emulator. This patch allows storageproxyd
to speak a length-framed RPMB to an external RPMB daemon.
For a concrete example of a daemon speaking this protocol, see rpmb_dev
in the Trusty tree.
