This change preserves any additional flags mount flags (e.g. MS_NODEV)
that any of the mounts would have. This avoids unnecessarily opening up
permissions, and also allows kernels that have additional restrictions
about what mount flags can be used to be happy with the remounts.

Fastboot protocol doesn't include zero packets,
so make it possible to configure that.
Allow fastbootd to see how many bytes the handle
can read/write at once.

Previously, read and write would return 0
on success. Now it will return the number
of bytes read/write. This is more consistent
with other usb handles and is needed in order
to handle partial packets (for fastbootd).
Update usb_write in other usb handles
to return amount written.
Change transport_usb accordingly.

Fastbootd will reuses adb's functionfs transport

Move it to daemon/include as well so it can be accessed
with "adbd/usb.h". Otherwise usb.h will conflict with
other imports.

When pushing to a path, we first try to ensure the directory path
exists and has the permissions expected by fs_config. Due to a change
that changed the fs_config check from a blacklist to a whitelist, we
started doing this for /data (which doesn't begin with /data/), and the
UID/GID for that path was accidentally being reused for following path
segments that didn't exist, leading to a failed attempt to chown
/data/local/tmp/foo to be owned by system.

adbd has been built as a static executable since the same binary was
copied to the recovery partition where shared library is not supported.
However, since we now support shared library in the recovery partition,
adbd is built as a dynamic executable.
In addition, the dependency from adbd to libdebuggerd_handler is removed
as debuggerd is handled by the dynamic linker.
A few more modules in /system/core are marked as recovery_available:
true as they are transitive dependencies of the dynamic linker.
This change also includes ld.config.recovery.txt which is the linker
config file for the recovery mode. It is installed to /etc/ld.config.txt
and contains linker namespace config for the dynamic binaries under
/sbin.

When using "adb remount" on a deduplicated filesystem, the current
response is a warning that the remount will not work. This patch
allows the user to specify an -R option. This option will reboot to recovery,
run e2fsck to undo deduplication, and then reboot the device where "adb
remount" will then succeed.
In addition, if verity needs to be disabled to remount, it will be disabled in
the same reboot cycle to minimize reboots.

Remove fdevent_install and fdevent_remove in favor of using
fdevent_create and fdevent_destroy, so that we can put RAII types (i.e.
unique_fd) into fdevent without worrying about -Wexit-time-destructors
or structs that are freed instead of deleted.

io_submit sleeps waiting for the gadget
to be enabled. Currently if that sleep
is interrupted it will shut down adb,
causing it to have to start back up again.
Rather than return EINTR if interrupted,
io_submit actually completes and the EINTR
is found later when looking through events.
Since an io that is interrupted will be
small anyway, add a loop to retry small ios.
Also upgrade aio logs in accordance with
their importance.

Test: adb works, logs show successful interrupt handling

A deduplicated filesystem might not have enough free space to undo its

Profiling of adb_benchmark revealed that something like half of the CPU
time was being spent in malloc and free, which was odd because the
benchmark repeatedly mallocs and frees allocations of the same size. It
turns out that our default configuration of jemalloc will purge after
every free. Configure jemalloc to not do this, for gains of over 100%
on adb_benchmark, and up to 25% (on walleye USB3) in real-life.

Previously, processes started via `adb shell` have an oom_score_adj of
-1000, making them invisible to the oom killer. This makes running a
process that consumes all memory (e.g. by leaking in a loop) lead to
the entire rest of the system (including adbd, because of bad
heuristics in the kernel) being oom killed before getting to it.
