We return the minor version number 15 to FUSE_INIT since we don't handle
BATCH_FORGET. Thus the kernel does not accept the latest size of
fuse_init_out. Instead we need to use FUSE_COMPAT_22_INIT_OUT_SIZE.
Previously the code unintentionally used FUSE_COMPAT_22_INIT_OUT_SIZE always
because we override the minor version out->minor to 15. Because sdcard.c shares
the buffer for |in| and |out|, it overrides the version number of in->minnor as
well.
The if closure in the previous code "if (in->minor <= 22)" was always true. The
CL removes the if closure to explicitly use FUSE_COMPAT_22_INIT_OUT_SIZE always.

Test: Manually boot Android and check if the storage shows up in Settings app.

- Add TEMP_FAILURE_RETRY around all relevant system calls.
- Cleanup some of the read calls.
- Add error log messages when read/write calls do not actually read/write the
expected number of bytes.
- Add error messages for write failures in fuse_status/fuse_replay.
Test: Attached to the sdcard process and stepped through most of the modified
Test: code. Also, create/read/write/delete files in /storage/emulated/0
Test: directory.

Instead default-initialize to 0. The third field, which is by
default padding, may be renamed and used in some implementations.

"PRI{u,x}64" was not compiling on C++ because of macro expansions.
Implement DLOG the same way DCHECK is implemented in
<android-base/logging.h>, and mechanically replace the problematic
lines with C++ logging. Remaining TRACE() lines will be replaced in a
follow-up CL.

Having CaseInsensitiveCompare use strcasecomp is not ideal, but other
solutions are not prettier.
Also, add a TODO to fix FUSE_TRACE, broken by the switch to C++.

Fix string literals and cast void* appropriately. Alternatively, we
could switch some of the allocations to new/delete, but we would need
to make sure that none of those end up passed to other code that will
call free(3) on them.
