a395b35d33 perf tools: Remove unneeded magic.h include from util.h 
Not used anymore, IIRC it was for useless PROC_FS_MAGIC procfs checks,
but those are long gone.

4ffde49246 perf test bpf: Use epoll_wait() instead of epoll_pwait() 
The prototype for epoll_wait() is available in older distros, so use it
instead of epoll_pwait() (removing the last NULL arg, the sigmask,
makes it the same thing anyway) to avoid breaking the build.

c4b6014e8b tools: Add copy of perf_event.h to tools/include/linux/ 
We shouldn't use headers from the kernel sources directly, instead we
should use the system's headers or in cases where that isn't possible,
like with perf_event.h, where the introduction of kernel features such
as perf_event_attr.{write_backwards,sample_max_stack} and
PERF_EVENT_IOC_PAUSE_OUTPUT take some time to become available in
/usr/include/linux/perf_event.h we need a copy.

Do it and check for source code drift, emitting a warning when changes
are detected.

c8b5f2c96d tools: Introduce str_error_r() 
The tools so far have been using the strerror_r() GNU variant, that
returns a string, be it the buffer passed or something else.

But that, besides being tricky in cases where we expect that the
function using strerror_r() returns the error formatted in a provided
buffer (we have to check if it returned something else and copy that
instead), breaks the build on systems not using glibc, like Alpine
Linux, where musl libc is used.

So, introduce yet another wrapper, str_error_r(), that has the GNU
interface, but uses the portable XSI variant of strerror_r(), so that
users rest asured that the provided buffer is used and it is what is
returned.

This script helps to create bonding network devices based on synthetic NIC
(the virtual network adapter usually provided by Hyper-V) and the matching
VF NIC (SRIOV virtual function). So the synthetic NIC and VF NIC can
function as one network device, and fail over to the synthetic NIC if VF is
down.

Mayjor distros (RHEL, Ubuntu, SLES) supported by Hyper-V are supported by
this script.

c09615f29c perf ui stdio: Add way to setup the color output mode selection 
In --stdio we turn off color output when the output is not a tty,
which is not always desirable, for instance, in:

  perf annotate | more

the 'more' tool is perfectly capable of processing the escape sequences
for colored output.

Allow using the existing logic for .perfconfig's "color.ui" to be used
from the command line by providing a stdio__config_color() helper, that
will be used by annotate and report in follow up patches.

0ea5ad869c objtool: Fix STACK_FRAME_NON_STANDARD macro checking for function symbols 
Mathieu Desnoyers reported that the STACK_FRAME_NON_STANDARD macro
wasn't working with the lttng_filter_interpret_bytecode() function in
the lttng-modules code.

Usually the relocation created by STACK_FRAME_NON_STANDARD creates a
reference to a section symbol like this:

  Offset              Type            Value               Addend Name
  000000000000000000  X86_64_64       000000000000000000   +3136 .text

But in this case it created a reference to a function symbol:

  Offset              Type            Value               Addend Name
  000000000000000000  X86_64_64       0x00000000000003a0      +0 lttng_filter_interpret_bytecode

To be honest I have no idea what causes gcc to decide to do one over the
other.  But both are valid ELF, so add support for the function symbol.

An important information for the napi_poll tracepoint is knowing
the work done (packets processed) by the napi_poll() call. Add
both the work done and budget, as they are related.

Handle trace_napi_poll() param change in dropwatch/drop_monitor
and in python perf script netdev-times.py in backward compat way,
as python fortunately supports optional parameter handling.
