We can't use InterruptWaitKey() as it hangs recovery
when called from the minadbd listener thread, so provide
our own 'CancelWaitKey' implementation.
[forkbomb: rework for Q]
Squashed:
recovery: Move sideload (non)cancellation to its own key
* We use KEY_REFRESH for actually refreshing menus, which is
useful when handling hotpluggable storage.
We don't want that to interact with the sideload menu.

After a reboot function call, we should always wait for it to finish
without executing other instructions.

Then we can override this function in the device specific recovery ui;
and allow customizing the help message.

The following variables in recovery ui were protected by
key_queue_mutex. But the purpose of key_queue_mutex is to protect the
key_queue, which will be changed after we already have a key code. So
getting the key pressed should be orthogonal to the key queue. And
adding a mutex will help to avoid deadlocks in b/135078366.
Variables include:
char key_pressed[KEY_MAX + 1];
int key_last_down;
bool key_long_press;
int key_down_count;
bool enable_reboot;

Waitkey() is designed to obtain lock "key_queue_mutex" in
the very beginning of function.
int RecoveryUI::WaitKey() {
std::unique_lock<std::mutex> lk(key_queue_mutex);
...
}
However, there's case "key_queue_mutex" being applied again in
waitkey(), thus cause deadlock. There are two reproduce
scenario:
1.Executing "fastboot reboot recovery" in userspace
fastboot
2.Executing "adb reboot fastboot" in recovery os
When entering userspace fastboot/recovery, waitkey()
will wait there for user action. fastboot/adb commands
will trigger ui->interruptkey() to notify the thread
waitkey() in. In the next, waitkey() will move on and call
SetScreenSaveState(), which do LOG(ERROR) in fail case of
brightness set. LOG(ERROR) is designed to print log on
UI. Unfortunately, UI->print() applies lock "key_queue_mutex"
too, so deadlock happen.
Note:
Here is details how lock "key_queue_mutex" applied in
UI->print():
Function Print() call
Function PrintV() call
Function update_screen_locked() call
Function draw_screen_locked() call
Function draw_menu_and_test_buffer_locked() call
Function IsLongPress()
bool RecoveryUI::IsLongPress() {
std::lock_guard<std::mutex> lg(key_queue_mutex);
bool result = key_long_press;
return result;
}

"reboot,userrequested,recovery"
"reboot,userrequested,recovery,ui"
"shutdown,userrequested,fastboot"

This reverts commit 6f4e4db4f9.
Reason for revert: Booting out of recovery (choose `Reboot system now`)
on taimen is broken. Device keeps booting back into recovery.
Bug: 133326470
Test: Choose `Reboot system now` from recovery menu. Deivce attempts
normal boot.

Test: Choose `Reboot system now`, `Power off`, `Reboot to bootloader`
from recovery UI respectively.
Test: `adb reboot recovery` while under sideload mode.
