For unclear reasons, it seems that for some people, devices are
becoming accessible, inaccessible, and then inaccessible again.
Switch to a sleep for now.

If a device is unplugged while it's being processed, we can be inside
register_usb_transport still when we call unregister_usb_transport,
leading to bad things happening. Move the call of
register_usb_transport into the scope guarded by usb_handles_mutex.

Previously, we would attempt to delete a usb_handle in both
device_disconnected and usb_close. If the one in device_disconnected
happened to happen first, usb_close would abort when it failed to find
the handle it was supposed to own.

fork() subprocesses to handle uevents in parallel.
This reduces coldboot time on bullhead from ~446ms to ~230ms.
This reduces coldboot time on sailfish from ~690ms to ~360ms.
This reduces coldboot time on ryu from ~187ms to ~122ms.

* changes:
debuggerd_client: increase pipe buffer size to max.
crash_dump: don't notify ActivityManager if it crashed.
crash_dump: clear the signal mask.
If a process tries to dump itself (e.g. system_server during ANRs),
crash_dump will block trying to write to its pipe if it's not
sufficiently large. Increase the pipe size to the max, and add a test
to make sure that it's always at least 1MB (the default value).

crash_dump inherits its signal mask from the thread that forked it,
which always has all of its signals blocked, now that sigchain respects
sa_mask.
Manually clear the signal mask, and reduce the timeout to a
still-generous 2 seconds.

Test: manually inserted sleep in crash_dump

Because the zram_size type is unsigned int.so if ZRAM size great
than 2^31 -1, zram_fp will receive a negtive integer, while the
ZRAM driver only accept natural number.We need to use printf
formatting %u instand of %d.
Test: 1. Config the zramdisk size 2348810240 and build a ramdisk
2. Reflash device and check below command:
$adb shell dumpsys meminfo
$ adb shell cat /sys/block/zram0/disksize
ZRAM info display will be abnormal
3. Config the zramdisk size 2348810240 and apply with this
patch.
4. Retest to step 2 and the ZRAM info will be ok.

init uses /acct and optionally /dev/memcg for tracking services and
therefore these must be started before any services start.
Test: check that cgroups are mounted appropriately.

mke2fs tool takes a filename and has its own open function to handle

Move the invocation of adb_notify_device_scan_complete to
the end of device_connected, where we decrement connecting_devices.
Also, create a dedicated thread for handling hotplug events, instead of
reusing the main thread for this, since the main thread blocks until
device scan is complete.
Test: `adb kill-server; adb devices`
