Integer overflow sanitized builds are throwing an error on the while
loop decrement in the rfind function. This refactors the loop to prevent
decrementing the value on the final iteration.
Test: Compiled and device boots without runtime error.

Partners (entities other than AOSP) can expose their own system
libraries which are in /system/lib[64] to Android apps. This can be done
by adding the name of the libs into the files
/system/etc/public.libraries-<companyname>.txt.
There can be multiple of the txt files on a device, which is for the
case that multiple partners contributing to the same system image
have their own set of public libraries.
The public libraries MUST be named as lib<name>.<companyname>.so. This
is to prevent accidental exposure of AOSP-defined system private libs.
Note 1:
<companyname> doesn't need to be the same as the value of the sysprop
ro.product.manufacturer or anything that can be part of a file path.
Note 2:
This feature is not for exposing SoC-specific libs to Android apps. That
is already done by /vendor/etc/public.libraries.txt and is only for
libs in /vendor/lib[64].

Reduce the amount of time that a process remains paused by pausing its
threads, fetching their registers, and then performing unwinding on a
copy of its address space. This also works around a kernel change
that's in 4.9 that prevents ptrace from reading memory of processes
that we don't have immediate permissions to ptrace (even if we
previously ptraced them).

- Add a load_bias field in MapInfo so that it can be loaded offline,
and also so it can be cached.
- Add an Add function to the Maps class so that it's possible to manually
create a map.
- Remove the OfflineMaps class since I haven't found a reason for this to
exist.
- Add a pointer to the gnu debugdata compressed section in the interface
itself and modify the step path to try eh_frame, then debug_frame, then
gnu_debugdata. This way arm can add exidx as the last step behind
gnu_debugdata. Add an offline test to verify the order of unwind.
- Fix x86_64_ucontext_t since it was a different size on 32 bit and 64 bit
systems.
Test: Pass new unit tests.

Paths for extended VNDK libs don't need version suffix, because there
always is the single version that the vendor(odm) modules are built
against.
Bug: 70601582
Test: walleye boots to the UI.
Test: No further test is possible since we don't have extended VNDK yet
in our source tree.

Re-format the files by splitting lines using +=.
Also add /odm/${LIB} where needed.
A few directories that are no longer required are removed from the
search paths and permitted paths.
Test: walleye and sailfish boots to the UI, renderscript, camera,
camcodder, sound, etc. are working.

Current syntax of the fstab in device tree (fstab_dt) assumes the
node name is the mount point, which doesn't allow subdir:
vendor { <== using "vendor/abc" leads to syntax error in device tree
compatible = "android,vendor";
dev = "/dev/block/platform/soc.0/f9824900.sdhci/by-name/vendor";
type = "ext4";
mnt_flags = "ro,barrier=1,inode_readahead_blks=8";
fsmgr_flags = "wait";
};
This CL adds a new field "mnt_point" in the fstab_dt configuration:
vendor_abc {
compatible = "android,vendor_abc";
dev = "/dev/block/platform/soc.0/f9824900.sdhci/by-name/abc";
type = "ext4";
mnt_flags = "ro,barrier=1,inode_readahead_blks=8";
mnt_point = "/vendor/abc"; <== new field
fsmgr_flags = "wait";
};
The new field is optional and will fallback to using node name as mount
point if it is absent.
Note that this CL also sorts fstab_dt by mount point, because
/vendor needs to be mounted first, which contains a directory
/vendor/abc, before /vendor/abc can be mounted.

Test: first stage mount /vendor/abc on a device

Currently, we only check if the name of a given node in the trie is a
prefix match and the prefix matches array of the final node. This is
incorrect however, as the prefix matches array of intermediate nodes
may contain the prefix for a given property. This change adds that
check and test cases for this case.

The interface lib has been in VNDK-SP because
android.hardware.graphics.mapper@1.0 was using it. However, since the
dependency has gone [1], there is no need keep it in VNDK-SP. The
VNDK-SP set should be kept as small as possible because libs in VNDK-SP
are subject to double-loading.
