perf debug: Add debug_set_file function

Allow to set debug output file via new debug_set_file function.

It's called during perf startup in perf_debug_setup to set stderr file
as default and any perf command can set it later to different file.

It will be used in perf daemon command to get verbose output into log
file.

Pull irqchip fixes from Marc Zyngier:

- Revert the wholesale conversion to platform drivers of the pdc, sysirq
and cirq drivers, as it breaks a number of platforms even when the
driver is built-in (probe ordering bites you).

- Prevent interrupt from being lost with the STM32 exti driver

- Fix wake-up interrupts for the MIPS Ingenic driver

- Fix an embarassing typo in the new module helpers, leading to the probe
failing most of the time

- The promised TI firmware rework that couldn't make it into the merge
window due to a very badly managed set of dependencies

Merge tag 'perf-tools-2020-08-14' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

Pull more perf tools updates from Arnaldo Carvalho de Melo:
"Fixes:
- Fixes for 'perf bench numa'.

- Always memset source before memcpy in 'perf bench mem'.

- Quote CC and CXX for their arguments to fix build in environments
using those variables to pass more than just the compiler names.

- Fix module symbol processing, addressing regression detected via
"perf test".

- Allow multiple probes in record+script_probe_vfs_getname.sh 'perf
test' entry.

Improvements:
- Add script to autogenerate socket family name id->string table from
copy of kernel header, used so far in 'perf trace'.

- 'perf ftrace' improvements to provide similar options for this
utility so that one can go from 'perf record', 'perf trace', etc to
'perf ftrace' just by changing the name of the subcommand.

- Prefer new "sched:sched_waking" trace event when it exists in 'perf
sched' post processing.

- Update POWER9 metrics to utilize other metrics.

- Fall back to querying debuginfod if debuginfo not found locally.

Miscellaneous:
- Sync various kvm headers with kernel sources"
