This works around a deadlock when a bridge that is about to be closed
is reused for a new call to openFile. The call to open() ends up holding
the vold lock, waiting for appfuse to respond. The appfuse event loop
calls onClosed(), which ends up calling vold.unmountAppFuse(), which
cannot get the lock.
Closing this file descriptor causes any current calls to open() on its
mount path to fail with either ECONNABORTED or ENOTCONN, allowing the
event loop to make progress, call onClosed() and unmount the path.
Note that the failed call to open() will result in a retry, which
will create a new appfuse bridge. This is not ideal but not a new
problem -- the common case here is that that each call to
openProxyFileDescriptor creates a new bridge. This should ideally
be improved.

When reading/writing proxy FD, if it returns EAGAIN,
BridgeEpollController updates epoll entries to observe specific FD
events. Before updating epoll entries, BridgeEpollController checks if
it really needs to update by comparing |state_| and |last_state_|.
|last_state_| has not been updated correctly so it resulted in wrong
epoll settings and keeps blocking the event loop.

Currently, if init encounters a fatal issues it reboots to fastboot
but this may be not desirable in all cases, especially the case of
critical services crashing. Therefore this change adds the ability
for vendors to customize the reboot target via the
androidboot.init_fatal_reboot_target= kernel command line.
This applies to all LOG(FATAL) messages as well as fatal signals in
userdebug/eng builds, except for signals before logging is enabled in
first stage init.

Dump init stacks when aborting either due to LOG(FATAL) or in
userdebug/eng builds due to signals, including signals from
sanitizers.
Doesn't work for static first stage init yet, b/133450393 tracks

Also, ensure that LOG(FATAL) in child processes calls abort() in all
stages of init, not just 2nd stage init.

non-aio USB read function was stuck in a loop waiting for more data
because data length parameter is always set 64 for fastbootd commands.
It should be a normal case to get less data than expected
since lengths of these commands are usually less than 64.
Add logic to check this and one more parameter to distinguish
fastbootd from general adbd case.

In device root directory, we have the following symlinks:
- /odm/app -> /vendor/odm/app
- /odm/bin -> /vendor/odm/bin
- /odm/etc -> /vendor/odm/etc
...
This allows the Generic System Image (GSI) to be used on both devices:
1) Has a physical odm partition, where those symlink will be hidden
when /odm is used as the mount point
2) Has no physical odm partition and fallback to /vendor/odm/.
We can't just have the symlink /odm -> /vendor/odm, because the former
devices won't have /vendor/odm directory, which leads to mount failure
when the mount point /odm is resolved to /vendor/odm.
The existing /vendor/odm/build.prop won't be loaded in the latter
devices, because there is no symlink
- /odm/build.prop -> /vendor/odm/build.prop.
Note that init blocks reading through direct symlinks (O_NOFOLLOW) so
the above symlink won't work either. This CL moves the odm build.prop
to /odm/etc/build.prop for init to load it (symlinks in earlier
components of the path will still be followed by O_NOFOLLOW).

Currently, during a 'fastboot flashall/fastboot update', the 'getvar
max-download-size' command is issued once to the device when it is in
bootloader mode and the same value is used even after the device boots
into fastbootd. If the max-download-size returned by bootloader is
greater than the max-download-size in fastbootd, this could break flash
as large images are broken down into chunks before downloading by using
the max-download-size variable. This will cause fastbootd to return
an error since it checks whether the buffer being downloaded has a size
greater than the max-download-size limit.

Controllers listed in cgroups.json file might fail to mount if kernel is
not configured to support them. We need a way to indicate whether a
controller was successfully mounted and is usable to avoid logging errors
and warnings when a controller that failed to mount is being used. Add
flags bitmask to cgrouprc controller descriptor and use a bit to indicate
that controller is successfully mounted. Modify cpusets_enabled() and
schedboost_enabled() functions to use this bit and report the actual
availability of the controller.

This keyword was introduced to support restarting services on devices
using APEX and FDE. The current implementation is not a restart, but
rather a 'reset' followed by a 'start', because the real /data must be
mounted in-between those two actions. But we effectively want this to be
a restart, which means that we also want to start 'disabled' services
that were running at the time we called 'class_reset_post_data'.
To implement this, keep track of whether a service was running when its
class was reset at post-data, and start all those services.

Regression from commit 77c28476f1
("Remove the mount points defined in skip_mount.cfg from
ReadDefaultFstab()") resulted in ReadFstabFromFile to report
errno ENOENT even upon success, preventing clear error propagation
for real failures (ReadFstabFromFile would _always_ report ENOENT).
The bad error propagation resulted in an adb remount failure.
Added immunization against future adjustments that may also
result in a similar regression in adb remount behaviors.
