This reverts commit cabca1b98e.
The hook android_rvh_binder_transaction is 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.

To avoid changing the visibiliy of data types when including
hook definition headers remove header file inclusions from
the hook definition header files.
Instead, the hook definition headers should just have forward
declarations that don't require full definition.
To provide full definitions of the types for the KMI, the
headers that define the types should be included by the
source file that instantiates the hooks - normally
vendor_hooks.c.
Since the KMI is frozen, some of the inclusions are still
required to preserve the CRC associated with symbols. Keep
these inclusions under #ifdef __GENKSYMS__.

When servicemanager process added service proxy from other process
register the service, we want to know the matching relation between
handle in the process and service name. When binder transaction
happened, We want to know what process calls what method on what service.

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,
7、android_vh_binder_preset: mark target proc's binder threads.
binder_has_work_ilocked may return true, so we try to wake up low-level thread immediately.

When vendor hooks are added to a file that previously didn't have any
vendor hooks, we end up indirectly including linux/tracepoint.h. This
causes some data types that used to be opaque (forward declared) to the
code to become visible to the code.
Modversions correctly catches this change in visibility, but we don't
really care about the data types made visible when linux/tracepoint.h is
included. So, hide this from modversions in the central vendor_hooks.h file
instead of having to fix this on a case by case basis.
This change itself will cause a one time CRC breakage/churn because it's
fixing the existing vendor hook headers, but should reduce unnecessary CRC
churns in the future.
To avoid future pointless CRC churn, vendor hook header files that include
vendor_hooks.h should not include linux/tracepoint.h directly.
