The first_stage_mount code for DSUs predates both the DSU name and the
ImageManager abstraction. Move this code to ImageManager, so it can be
shared with overlayfs/scratch handling. And while we're here, rename GSI
to DSU for clarity.

Simplifications/changes:
(1) We remove the bufPos field and track the end of the buffer using
only the size field.
(2) We rename put_<type>() functions to append_<type>() to signify that the
value will be placed at the end of the buffer. We also move the
increment of event->size to within the append_<type>() functions;
this improves readability of the write_<type>() functions.
(3) We immediately write the timestamp and atom id to the buffer in
order to simplify stats_event_build().
(4) We never check for null pointers; checking for null pointers
delays errors and obfuscates the root problem.
(5) We change the the annotationId and numPairs parameters to be
uint8_t's. This helps signify to clients that these values must fit
in 1 byte.
(6) Clients no longer have to pass in the length of strings. Instead, we
expect them to pass in null-terminated strings, and we will
calculate the length outselves using strnlen.

Encoding of key-value pairs follows strategy described in
go/statsd-socket-doc.
Fixed bug where timestamp and atom id were not contributing to the
number of fields in the buffer.
Note: Similar to ag/9603344, which was abandoned because of git rebasing
issues.
Test: m -j libstatssocket compiles

This allows the parsing code within statsd to access the type ids.
Also, we move stats_event.h to the include directory for consistency.

We use /data/incremental to keep all the directories that are mounted on
the Incremental File System.
Since system_server does not have permission to dynamically create dirs
directly under /data, we create /data/incremental in init.rc.

These weak symbols are no longer necessary because we no longer
need to statically link libvndksupport.
Furthermore, these symbols are not really optional when libvndksupport is
dynamically linked. When the library is linked with --as-needed the linker
may drop the reference to libdl_android.so, which leads to a failure to boot.

This fixes two bugs in how we use fallocate(). First, using ZERO_RANGE
is a mechanism to allocate holes, not blocks. Instead we should be
passing no flags.
The reason this code worked is because of our explicit writes to the
file, which is intended to defeat lazy block allocation. This is not
necessary for F2FS with proper file pinning support, so we now skip this
when possible.
Together, these fixes improve the speed of "adb remount" when backed
by libfiemap.

d77c99ebc3 changed MappedFile to return a
bogus zero-length mapping on failure rather than nullptr. None of the
calling code was changed, though, and it seems like doing so would be a
bad idea. Revert that part of the change.
Add missing tests, and tidy up some of the logging. Also remove
single-use or obfuscatory constants from the tests.
The new "empty.zip" was created by using zip(1) to create a zip file
with one entry, then using `zip -d` to remove it.
The new "zero-size-cd.zip" was created by using zip(1) to create a zip
file containing a single empty file, and then hex editing the two byte
"size of the central directory" field in the "end of central directory
record" structure at the end of the file. (This is equivalent to, but
much smaller than, the example zip file provided by the bug reporter.)

This reverts commit 5d53bfce2d.
Reason for revert: for consistency, we've decided that for now, all code will have the same view of /storage: FUSE. Will address the TODO here later.

In recovery the user has the option to mount /system, but when a device
is updating with Virtual A/B, the _b partition may be a snapshot.
This patch introduces a helper function that satisfies the dependency of
setting up the snapshot devices required to mount /system.
