When init found "/force_debuggable" in the first-stage ramdisk, it will
do the following if the device is unlocked:
1. load /system/etc/adb_debug.prop (with ro.debuggable=1)
2 .load userdebug_plat_sepolicy.cil instead of original plat_sepolicy.cil from
/system/etc/selinux/.
This make it possible to run VTS on a USER build GSI, by using a special
ramdisk containing "/force_debuggable".

Test: unlock a USER build device, check 'adb root' can work
Change-Id: I9b4317bac1ce92f2c0baa67c83d4b12deba62c92
As there is no security guarantee when the device is unlocked,
allowing adb root gives us more rooms to debug a USER build images.
Also, this makes it possible to run VTS on a USER build GSI, with
setting ro.debuggable=1 and unlocking the device.
This basically re-lands a reverted change:
https://android-review.googlesource.com/c/platform/system/core/+/437815
Which isn't needed after we moved /sbin/adbd to /system/bin/adbd in
USERDEBUG GSI. But it's still needed for USER build GSI.

The existing location of logic for creating symlinks to files that have
moved into APEX does not get executed for -user builds, only
-userdebug and -eng. The new location is equally arbitrary but appears
to be invoked for -user, -userdebug and -eng targets.
Tested with:
make cleaninstall && lunch taimen-[user|userdebug|eng] && make droid
Inspected:
ls -l out/target/product/taimen/system/usr/icu

(cherry picked from commit 0ed52b789d)
FIBMAP blocks are returned in FIGETBSZ units, which means the number of
blocks also needs to be determined by FIGETBSZ. Using the stat blocksize
is incorrect. On VFAT, FIGETBSZ returns 512 whereas st_blksize is 32768.

Changes:
- Change GetSoname to always returns a std::string.
- Added new unit tests for the soname printing.
- Modify the GetElf() function to save the same elf when we see rosegment
linkers that split the read-only and read-write across a map. This
avoids creating multiple elf objects for each map.
- Fixed a few offline unwind tests.

Bind-mounting of the bionic files on /bionic/* paths no longer required
as there are direct symlinks from bionic files in /system partition to
the corresponding bionic files in the runtime APEX. e.g.,
/system/lib/libc.so -> /apex/com.android.runtime/lib/bionic/libc.so

The path no longer exists, and thus the path doesn't need to be
unmounted upon remounting.

We allocate VFAT file space by seeking and writing a single byte. It
turns out this is not fast enough to avoid invoking the progress
callback, so instead, we should seek in increments.

Fix wp and sp comparison bugs
Make clear() actually clear wp m_refs, so that nulls compare equal.
Make equality consistent with < and >, ensuring that a weak pointer
cannot be both equal to and greater than another.
Don't rely on the built-in < and > operators to correctly order
different objects. The standard does not guarantee that, and there is
a risk of compiler relying on that lack of guarantee.
Remove unnecessary comparison overloads, especially those
comparing a wp<> to an sp<>.
Change the remaining wp<> to sp<> comparisons to check for equivalence
of the mRefs pointer instead of the object address, thus eliminating
the dubious equal comparison result for a dead wp<> and an sp<> that
happen to point to the same object address.
Add comparison tests.
This reverts commit a2a2ad8057.
The original code, and my original CL, both failed to initialize m_refs
in various wp<> constructors. This now became more important, since
comparisons now rely more on m_refs. However I believe it was always
a bug, since some comparisons always relied on m_refs.
