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.

This change is intended to reduce the chance of a missed ABI break
involving vendor hooks.
The following types are now fully defined in ABI XML.
* `struct binder_transaction`
* `struct binder_thread`
* `struct binder_proc`
* `struct printk_ringbuffer`
* `struct printk_record`
symbol '__alloc_pages' changed
CRC changed from 0x6497cbd to 0x230fd8e5
symbol '__find_vma' changed
CRC changed from 0xf11b619f to 0xb0069a61
symbol '__free_pages' changed
CRC changed from 0xba5eeb68 to 0xdc394265
... 195 omitted; 198 symbols have only CRC changes

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.

Add hooks to gather data of kernel fault and summarize it with
other information.
