When BT coexistence is enabled (eg oper mode 13, which is the default)
the initialisation on startup sometimes silently fails.

In a normal initialisation we see
	usb 1-1.3: Product: Wireless USB Network Module
	usb 1-1.3: Manufacturer: Redpine Signals, Inc.
	usb 1-1.3: SerialNumber: 000000000001
	rsi_91x: rsi_probe: Initialized os intf ops
	rsi_91x: rsi_load_9116_firmware: Loading chunk 0
	rsi_91x: rsi_load_9116_firmware: Loading chunk 1
	rsi_91x: rsi_load_9116_firmware: Loading chunk 2
	rsi_91x: Max Stations Allowed = 1

But sometimes the last log is missing and the wlan net device is
not created.

Running a userspace loop that resets the hardware via a GPIO shows the
problem occurring ~5/100 resets.

The problem does not occur in oper mode 1 (wifi only).

Adding logs shows that the initialisation state machine requests a MAC
reset via rsi_send_reset_mac() but the firmware does not reply, leading
to the initialisation sequence being incomplete.

Fix this by delaying attaching the BT adapter until the wifi
initialisation has completed.

With this applied I have done > 300 reset loops with no errors.

 - Fix hybrid config terms list corruption.

 - Update kernel header copies, some resulted in new kernel features
   being automagically added to 'perf trace' syscall/tracepoint argument
   id->string translators.

 - Add a file generated during the documentation build to .gitignore.

 - Add an option to build without libbfd, as some distros, like Debian
   consider its ABI unstable.

 - Add support to print a textual representation of IBS raw sample data
   in 'perf report'.

 - Fix bpf 'perf test' sample mismatch reporting

 - Fix passing arguments to stackcollapse report in a 'perf script'
   python script.

 - Allow build-id with trailing zeros.

 - Look for ImageBase in PE file to compute .text offset.

Currently perf saves a build-id with size but old versions assumes the
size of 20.  In case the build-id is less than 20 (like for MD5), it'd
fill the rest with 0s.

I saw a problem when old version of perf record saved a binary in the
build-id cache and new version of perf reads the data.  The symbols
should be read from the build-id cache (as the path no longer has the
same binary) but it failed due to mismatch in the build-id.

  symsrc__init: build id mismatch for /home/namhyung/.debug/.build-id/53/e4c2f42a4c61a2d632d92a72afa08f00000000/elf.

The build-id event in the data has 20 byte build-ids, but it saw a
different size (16) when it reads the build-id of the elf file in the
build-id cache.

A config terms list was spliced twice, resulting in a never-ending loop
when the list was traversed. Fix by using list_splice_init() and copying
and freeing the lists as necessary.

Currently, nothing is output on the serial console, unless
"console=ttyS0,115200n8" or "earlycon" are appended to the kernel
command line.  Enable automatic console selection using
chosen/stdout-path by adding a proper alias, and configure the expected
serial rate.

While at it, add aliases for the other three serial ports, which are
provided on the same micro-USB connector as the first one.
