737ef7d32c tools include: Copy linux/stringify.h from the kernel
There is code in tools/ that is directly including this file from the
kernel, and this is verboten for a while, copy it so that the next csets
can fix this situation.

1698872b5c tools: Copy hashtable.h into tools directory
Copy hashtable.h from include/linux/tools.h.  It's needed by objtool in
the next patch in the series.

Add some includes that it needs, and remove references to
kernel-specific features like RCU and __read_mostly.

Also change some if its dependency headers' includes to use quotes
instead of brackets so gcc can find them.

d1b39d41eb tools: Make list.h self-sufficient
Commit 7f5f873c6a ("rculist: Use WRITE_ONCE() when deleting from
reader-visible list") added the use of the WRITE_ONCE macro to the
kernel version of list.h, which broke the stacktool build because the
tools list.h includes the kernel list.h.

Avoid this type of situation in the future and make list.h
self-sufficient by copying the kernel list.h routines directly into
tools list.h.

This is a straight copy except for adjustments to the include statements
and copying of the tools-specific list routines (list_del_range and
list_for_each_from).

c95f343211 tools include: Fix strict-aliasing rules breakage
Vinson reported build breakage with gcc 4.4 due to strict-aliasing.

   CC       util/annotate.o
 cc1: warnings being treated as errors
 util/annotate.c: In function ‘disasm__purge’:
 linux-next/tools/include/linux/compiler.h:66: error: dereferencing
 pointer ‘res.41’ does break strict-aliasing rules

The reason is READ_ONCE/WRITE_ONCE code we took from kernel sources.  They
intentionaly break aliasing rules. While this is ok for kernel because it's
built with -fno-strict-aliasing, it breaks perf which is build with
-Wstrict-aliasing=3.

Using extra __may_alias__ type to allow aliasing in this case.

dabf626f7f perf tools: Copy linux/filter.h to tools/include
This patch copies filter.h from include/linux/kernel.h to
tools/include/linux/filter.h to enable other libraries to use macros in it,
like libbpf which will be introduced by further patches.

Currently, the filter.h copy only contains the useful macros needed by
libbpf for not introducing too much dependence.

tools/perf/MANIFEST is also updated for 'make perf-*-src-pkg'.

One change:
  The 'imm' field of BPF_EMIT_CALL becomes ((FUNC) - BPF_FUNC_unspec) to
  suit user space code generator.
