This reverts commit acefa91e51.
The hooks trace_android_vh_binder_proc_transaction_entry and
trace_android_vh_binder_select_worklist_ilocked are not used by any
vendor, so remove it to help with merge issues with future LTS releases.
If this is needed by any real user, it can easily be reverted to add it
back and then the symbol should be added to the abi list at the same
time to prevent it from being removed again later.

ANDROID_VENDOR_HOOKS has implicit dependencies on the subsystems which
it hooks into whenever it directly uses an "internal" header for that
system. For instance, drivers/scsi/ufs/ufshcd.h doesn't compile unless
CONFIG_SCSI_UFSHCD is enabled:
In file included from drivers/android/vendor_hooks.c:41:
In file included from include/trace/hooks/ufshcd.h:21:
include/../drivers/scsi/ufs/ufshcd.h:675:38: error: field has incomplete type 'struct devfreq_simple_ondemand_data'
struct devfreq_simple_ondemand_data ondemand_data;
^
include/../drivers/scsi/ufs/ufshcd.h:675:9: note: forward declaration of 'struct devfreq_simple_ondemand_data'
struct devfreq_simple_ondemand_data ondemand_data;
To avoid these implicit dependencies, guard any "internal" header
includes with the respective CONFIG_ options when applicable. If the
CONFIG_ option is not enabled, then the forward-declared structs are
used. This is acceptable because those hooks would not have been called
anyway since the underlying subsytem wasn't enabled.

trace_android_vh_binder_proc_transaction_entry:
We need change binder thread so that this work can be added in
proc->todo, if we found the binder thread, skip native logic.
trace_android_vh_binder_select_worklist_ilocked:
we need this because we can't change list point in ”trace_android_vh_binder_thread_read“,
otherwise, If a work has beed added in our own defined list before,
current may goto retry and loop again and again.

We want to add some hooks in the binder module so that we can reduce
block time until binder thread is available
Here are what new hooks do for:
1、android_vh_binder_looper_state_registered: choose a binder thread(do proc work) as a low-level thread.Only this thread has power to excute background binder transaction.
2、android_vh_binder_thread_read: let binder thread do works which come from
our list.
3、android_vh_binder_free_proc: free some pointers and variable.
4、android_vh_binder_thread_release: free the list that we create before.
5、android_vh_binder_has_work_ilocked: to check if our list has work.
6、android_vh_binder_read_done: because of we add hook in binder_has_work_ilocked,
binder_has_work_ilocked may return true, so we try to wake up low-level thread immediately.

We want to get binder free space information in the binder
transaction, but this needs to hold the mutex lock. So we add
this restrict hook to do this.

Vendor hook is add in the commit:
https://android-review.googlesource.com/c/kernel/common/+/1687592
When we register the vendor hook and build, there is build error:
too long symbol "__tracepoint_android_vh_binder_transaction_priority_skip"
So, I shorten the function name
android_vh_binder_transaction_priority_skip -->
android_vh_binder_priority_skip

There are few vendor hooks available for binder wakeup related
functionality. As they both essentially do the same thing, we can
consolidate them into one.
