Starting from Android R, platform code cannot access files in debugfs
since it does not guarantee ABI stability. This CL removes the code in
storaged that accesses the EMMC's ext_csd register from debugfs as a
backup if it is unable to obtain the information from Health HAL.
Test: build and boot.

The test suite is still quite buggy if interrupted. This fixes a number
of issues (such as bad ordering of setup calls), and refactors things to
add more ASSERTs.

* changes:
liblp: Don't halve super partition for virtual a/b devices
liblp: MetadataBuilder::GetBlockDevicePartitionName
liblp_test_static: GetMockedInstance->GetMockedPropertyFetcher
libsnapshot: UnmapSnapshot: don't delete device that doesn't exist.
liblp: change some functions to use string_view
this makes libsparse compile with MacOS clang++
Test: "libsparse" compiles and works fine under both Linux and MacOS

This change fixes a bug that neuralnetworks namespace is linked to the
default namespace in [vendor] section. Default namespace is for
/vendor/lib in [vendor] section. System libraries are available in the
'system' namespace.

For Virtual A/B devices, we snapshot the partitions. Hence
there is no need to prioritize using the second half of super
partition for _b partitions.

Allow to retrieve name of a block device partition at
a certain index. If the index is out of range, return
empty string.
This is needed for an hypothetical edge case when an
intersection of two LinearExtent needs to be computed,
and the two metadata have a different list of block
device names. In reality, Virtual A/B devices are always
launched with dynamic partitions, so it will always return
"super" for index 0 and "" otherwise.

Converting all of them to string_view requires some
non-trivial amount of refactoring (because there is not
an implicit conversion from string_view to string), and
hence may be done later if necessary.

adb uses its own implementation of Windows HANDLE->int mapping,
and it doesn't play well with _get_osfhandle() function used in
MappedFile::FromFd().
This CL adds another function that accepts raw handle, so adb
can pass it directly
+ make constant functions 'const'
+ make the MappedFile movable, as nothing prevents it from being
one

__BIONIC__ is defined in sys/cdefs.h, __GLIBC__ is defined in
features.h (which is included from sys/cdefs.h). If sys/cdefs.h
was not included before android-base/endian.h it was always falling
back to the Windows definitions.
mingw defines LITTLE_ENDIAN, BIG_ENDIAN and BYTE_ORDER in
sys/params.h, use those definitions to avoid conflicts.
glibc uses different names for letoh*, add compatibily #defines.

The purpose of this is twofold. First, we need a way to detect whether
the device has booted into the new slot after an update. Second, we need
a quick-and-dirty test for first-stage init so it can avoid searching
for snapshots if it doesn't need to.
We can solve both of these problems by storing the source slot in
/metadata/ota/snapshot-boot. The existence of the file implies a more
complex check is needed, and the file stores the source slot.

Turns out that although there's no <endian.h> or <sys/endian.h>, there
are <machine/endian.h> and <sys/_endian.h>, and they're included by
other system headers such as <dirent.h>.
Reuse the contents of <sys/_endian.h> here for better interop.

It helps to fix a compilation issue with host libc:

For devices that do not have verity, or start the test with
verity disabled, but are using overlayfs, use a 'secret' surgical
technique to revert the device back to original state.
adb enable-verity will carry risk in that if the device did not
arrive with verity enabled, we can not guarantee it will boot
if we turn on verity.

When we have a property match along with an event trigger, we
currently don't allow matching empty property values, in other words,
properties that are unset. For example, the below trigger would never
be run:
on zygote-start && property:persist.sys.fuse=""
That doesn't make sense though, it should be possible to match an
empty property value, so this change allows that trigger to match when
persist.sys.fuse is either empty or not set.
This continues to not match a '*' to an empty property, so
on zygote-start && property:persist.sys.fuse=*
will not run if persist.sys.fuse is empty or unset.
Test: the above triggers run appropriately
