This is mostly a simple lexical search+replace but the absence of operator< for
std::weak_ptr<T> leads to some complications, particularly with Evoral::Sequence
and ExportPortChannel.
Plugin analysis uses a GUI thread instance of a given plugin to
perform a IR analysis.
Some plugins can be rather CPU expensive to analyze.
e.g. a-hi/lo-filter when interpolating is recalculating biquad
coefficients every 64samples during the 8k IR analysis. This can take
a significant amount of time on older CPUs.
Furthermore live-signal collection happens in the rt-thread,
using cross-thread signals. Signal collection is periodically initiated
from the same timeout signal as analysis.
Analysis is was done using default thread priority, which is higher
than the GUI redraw priority (PRIORITY_HIGH_IDLE).
So it was possible to contiguously initiate analysis, loading the CPU
and preventing redraws.

git history begins in 2005. So (C) from 1998..2005 is lost. Also some
(C) assignment of commits where the committer didn't use --author.
Plugin-analysis uses a fixed number of samples, which may be larger
than the session's block-size. This caused problems for some VST
plugins that use audioMasterCallback to query the session's block-size.
Plugin FFT analysis now processes in chunks of the session's block-size
to avoid this issue. This also allows to increase accuracy for
all plugin standards (FFT size was increased to 8192).
set_block_size() implies plugin deactivate(), activate() calls
to re-initialize AU and VST plugins. So plugins will reset the
internal state and not immediately respond correctly.
Some plugins zero the output or ramp up internally, leading the analyzer
to show invalid or random/uncorrelated information.
This avoid periodic calls to de/activate()

When freq was changed to be an integer, the conversion to kHz became a
truncation. Divide by the float 1000.0 to pass the correct value to the
stringstream formatting routine.
Pass current (latency compensated) cycle times to plugin.
This fixes time-reporting to plugins and also fixes automation
and when bouncing (the session->transport* is not valid) etc.
