This commits allows multiple lines in a fstab have the same mount
point for first-stage mount, where the first successful mount will be
used.
This allows us to specify a common/shared fstab, with different
settings (e.g., ext4, squashfs) per line, to mount different types
of images on the same mount point. e.g., allows the device to mount
GSI (ext4) while support mounting the original squashfs system.img.
Sample fstab:
fstab in dt:
android {
fstab {
odm_ext4 {
dev = "/dev/block/by-name/odm";
mnt_point = "/odm";
type = ext4;
mnt_flags = "ro";
fs_mgr_flags = "slotselect";
};
odm_f2fs {
dev = "/dev/block/by-name/odm";
mnt_point = "/odm";
type = f2fs;
mnt_flags = "ro";
fs_mgr_flags = "slotselect";
};
};
}
fstab in file:
/dev/block/by-name/odm /odm ext4 ro slotselect
/dev/block/by-name/odm /odm f2fs ro slotselect
Test: make & boot & check /proc/mounts

This commit has the following changes:
1. Builds libfs_avb via "fs_mgr/libfs_avb/Android.bp" instead of
"fs_mgr/Android.bp", and removes the libfs_avb source
dependencies on "fs_mgr/fs_mgr_priv.h".
2. Moves static functions in fs_avb.cpp into util.cpp or
avb_util.cpp, depending on whether the function is related to
AVB or not.
3. Introduces two host unit tests: libfs_avb_test and
libfs_avb_internal_test, the former is to test public
<fs_avb/fs_avb.h> APIs, while the latter is to test libfs_avb
internal functions.
4. Splits fs_avb_unittest_util.* into:
- fs_avb_test_util.* (host static lib: libfs_avb_test_util),
- basic_test.cpp (host executable: libfs_avb_test)

Removing restorecon on root sepolicy files because:
1. Under normal boot the files are properly labeled when creating the

2. These restorecon's are not required for recovery to function.

When testing adb-remount with overlayfs, vendor overlay may fail the
test because there are unexpected overlayfs uses by vendor overlay.
By excluding mount entries for vendor overlay, the test runs
regardless of vendor overlay mount.

A class will only load if there is not a property named

As bionic libs are moved from /system to the runtime APEX, anything that
is outside of the runtime APEX cannot use private symbols from the
bionic libs.
init is not included in the runtime APEX but is using private bionic
APIs: __system_property_[add|area_init|update|...]. So, it was required
to publicize the private symbols for init.
However, since init is started before the runtime APEX is activated, it
actually cannot use the bionic libs from the runtime APEX, but will use
the bootstrap bionic libs left in /system/bootstrap/lib[64]. Because
init and the bootstrap libs are in the same partition, init doesn't need
to link against the stubs of bionic libs. In order to make this
possible, the new property 'bootstrap' is set to true allow init to use
the bootstrap bionic.

Needed by showmap and also android_s_Debug to classify each allocation
into multiple heaps.
The APIs added are:
ForEachVmaFromFile - Global API to parse a file expected to be in the
same format as /proc/<pid>/smaps and make a callback for each VMA found.
ProcMemInfo::ForEachVma - Same as 'ForEachVmaFromFile' but for a
ProcMemInfo object corresponding to a process(pid).
ProcMemInfo::Smaps - Wrapper to ProcMemInfo::ForEachVma, except the
function collects 'struct Vma' in a member vector and returns the
reference for the same.
Added showmap2 using the APIs and the corresponding tests the same time.

This change removes this denial:
avc: denied { write } for comm="init" name="sda6" dev="tmpfs" \
ino=25715 scontext=u:r:init:s0 tcontext=u:object_r:system_block_device:s0 \
tclass=blk_file permissive=0
The reason is that during any mount_all in init,
fs_mgr_overlayfs_mount_all() will mount a list of candidates for
scratch, which includes system_other. However, in order to probe
if /overlay directory exist in the partition, it only needs read
access to the block device, and mount the partition as readonly.
If the block device is a true candidate (i.e. it does have /overlay),
re-mount it as writable.
Test: flash, wipe, boot, denial goes away, cppreopt is successful
Test: boot the second time, no denials (no cppreopt this time)

Some commands like 'adb_sh grep " rw," /proc/mounts' do not preserve
the embedded spaces when transferred to the device and thus do not
entirely behave as expected. There are several commands issued this
way throughout the test that are similarly broken. To add
consistency, pass any arguments that are not explicitly (double)
quoted and contain embedded spaces as quoted to preserve.
Also devices that report the kernel internal device /dev/root in
/proc/mounts should be suppressed when investigating whether
overlayfs is needed. If /dev/root is reported, then we should assume
that the mount point / represents it for the following df command
when trying to determine if the partition is right-sized.
When there is only one device attached, and a serial number is not
specified, correctly determine this condition to progress to
the testing.
