Tweak ALSA nperiod setting, fallback to nearest
This is mainly for RME RayDAT that has a fixed buffersize of 16k:

  dev_name : hw:HDSPMxc2f6c5,0
  channels : 36
  min_rate : 32000
  max_rate : 192000
  min_bufz : 16384
  max_bufz : 16384
  min_nper : 4
  max_nper : 512

However nperiod configuration determines the effective latency
regardless.

This is similar to https://github.com/jackaudio/jack1/blob/master/drivers/alsa/alsa_driver.c#L476-L486

Prepare to allow using ALSA backend with nperiods > 3
This will still need an update for Alsa_pcmi::set_hwpar() capture
channel (which is fixed at 2, unless FRAG_NEAR is used).

Fix ALSA available buffersize detection:
buffer-size = periods * period-size

Previously, buffersize was used for period-size.

This fixes an issue with a dedicated .asoundrc configuring a specific
period-size or buffer-size that has to be exact.
Ardour's device configuration failed in this case.

This has not been an issues since most hardware devices offer a wide
range: 8 < period-size < 262144 ; 16 < buffer-size < 524288.
Only a subset of which (32 .8192) is allowed by Ardour.

Skip name-suffix for first ALSA sub-device
This fixes an issue when a device has more than one
playback sub-device, but only a single capture sub-device (or vice
versa).

List available ALSA sub-devices
Previously Ardour only listed the first audio sub-device in the
for ALSA and JACK backend device selection dialog.

Fix ALSA MIDI device naming
The backend will replace the information in the last bracket (IO)
of the name with (In/Out) when creating pretty port-names from the
device-name. -- see replace_name_io().

This fixes an issue with device-name number suffixes in brackets.

Prepare for Ardour/ALSA multiple identical MIDI devices
The engine setup identifies devices by name (device list is a map<>
with the device-name as key). To support multiple devices with the
same name, the name needs to be unique.

So far this is achieved by simply adding a number suffix starting with
the 2nd device (this allows to re-use configurations).

Ideally we'd use UUIDs or unique device IDs to handle this, and also
somehow clarify which device is which...

0de5722fb1 Use PBD::to_string() from pbd/string_convert.h in ardour ALSA utils
Use pbd/string_convert.h API instead of std::ostream for numeric formatting to
remain locale independent and not have to use a LocaleGuard. The formatting is
equivalent

ba78359129 prepare for update to waf 1.8
uselib is no longer implicit (inherited by .use). This is still incomplete,
some uselibs for non-linux variants may be missing.

bld.is_defined("HAVE_XXX") also no longer works and will have to be
changed (I think to bld.env["HAVE_XXX"]) in countless places.
