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
error code in the case of an RPMB socket.

We were doing "return -1" in an error case from a function that
returns bool. Since it's non-zero, this gets implicitly cast to
'true', which almost certainly isn't what we wanted here.

This is needed for adb remount, to find the scratch device if it is
already mapped. Note that on devices without metadata encryption, this
cannot be done by querying device-mapper, since scratch will be a loop
device.

ImageManager can map images in recovery, but not delete them, because
/data is not mounted. libsnapshot handles this by storing extra state
files, but this is complex to manage and inconvenient for
fs_mgr_overlayfs.
Instead, this patch introduces two new calls:
- DisableImage(), which indicates the image should not be used. This is
implemented by adding a new DISABLED attribute to
LpPartitionMetadata. CreateLogicalPartitions ignores this flag, and
thus recovery/fastbootd can disable the scratch partition and
communicate that it can be deleted. This cannot be called from binder
since it is intended for recovery/first-stage init only.
- RemoveDisabledImages(), which walks the images for a given folder on
/metadata and deletes any that are disabled. This can be called from
binder.
Note that there is no metadata version bump for this flag. It's
considered to be included in the flag list for minor version 1, and
currently is not used for the actual super partition.

This eliminates libfiemap as a standalone library and instead bundles it
into libfs_mgr. All consumers of libfiemap need libfs_mgr, and having
them tightly coupled reduces linkage complexity.
When to use libfs_mgr: In recovery, first-stage-init, or when libfiemap
or overlayfs is not used.
When to use libfs_mgr_binder: When not in recovery/first-stage init, and
overlayfs or libfiemap is needed. In this case, IImageManager will proxy
over binder to gsid.

Rather than use a std::vector for backing memory, allocate the memory
using a new with nothrow, and in MemoryBuffer use realloc. Since
the size field is coming from the elf, it could be corrupted or
intentionally crafted to cause problems.
In addition, add some other protections to make sure that overflows
don't occur.

There are two namespaces from init - bootstrap and default - and those
will have different set of APEX modules. To support difference between
two namespaces, linker config should be generated per namespace and each
namespace should use its own linker configuration. As a first step of
the work, this change will create different mount point for each
namespace, and re-generate linker config after APEX mount from each
namespaces.

depended on ordering of entries. Instead fs_mgr now tries to unmount
everything with the same block device as /data until timeout is reached.
This is very similar to what is done in UmountPartitions in reboot.cpp,
but I'm a little bit reluctant to merge them together, since the later
unmount all read-write partitions, while here we are only interested in
/data.
