30b087ab3d globally change all use of "frame" to refer to audio into "sample".
Generated by tools/f2s. Some hand-editing will be required in a few places to fix up comments related to timecode
and video in order to keep the legible

7258c6334d Namespace PBD::RingBuffer
class RingBuffer<> is a very generic name and should not pollute the
global namespace.

4985f0d7ae Include last sample in reverse test for nonsilence in end trim during export 2016-12-06 20:55:17 +10:00
bd52d4e328 Fix issues in export with trim enabled
A complete reimplementation of AudioGrapher::SilentTrimmer::process to support
trimming the beginning and end in the same processing block

Fix export with trim end enabled to actually trim silent frames

Only add silence to beginning or end of export data if data was written

Should resolve: #6412

568cf861f9 Rename AudioGrapher::SilentTrimmer method to reflect behaviour
Unlike many of the other uses of the term "frame" this is actually returning
the index to the first sample in the interleaved frame that contains
non-silence.

2c67e71e98 Always signal writing to file is complete at end of the export process
With end trim enabled, the only case that would successfully export was if
there was at least some samples above the silence threshold in the last export
processing block.

The issue was that the EndOfInput flag was not being passed to
AudioGrapher::SndFileWriter::process which would then call sf_write_sync and
emit the FileWritten signal to start post processing. Fix that by always
passing the EndOfInput flag in the last export process cycle.

21bb604fc1 fix build of test suite
Fix build of audiographer tests after changes to TmpFile in 77687519.

77687519b6 Refactor TmpFile into an abstract base class
This allows a TmpFile pointer to be either a Sync or Async (Threaded)
writer. As result we must be able to handle both RT and non RT processing.

Still, post-processing (normalization and encoding) should always
happen faster than realtime (freewheeling).

Since jack does not allow a client to change to freewheeling from within
the process-callback, the async-writer disk-thread FileFlushed is used
to initiate post-processing.

e55ef88ee9 refactoring to prepare for real-time export
* add a threaded TmpFile Writer
* update API calls to that process_export_fw() can be used as
  process_function

The idea is to re-use export infrastructure from normalization:
export to a tmp-file and then encode target formats after that.

f00342b2d8 Some AudioGrapher classes need to be exportable now, to support newly introduced 'AnalysisGraph' class
(not entirely sure why - but it might be because 'ProcessContext<Sample>' is now used in multiple sources within libardour).

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.

lib/libfftw3f.a(apiplan.o):apiplan.c:(.text+0x430): multiple definition of `fftwf_destroy_plan'

This is because static symbols in a .dll have no fixed address and
are mapped when loading the dll. Static functions in .exe do have a fixed
address.
With a header-only implementation the functions are provided
libardour.dll and ardour.exe
