In the performance-log viewer, defer updates to the various UI
elements when the selection changes until they're actually shown.
This improves responsiveness when changing the selection.

Use the less-ambiguous, if just as clumsy,
"format-indent-more/less" icons, to stand for the
caller -> callee, and callee -> caller, directions, respectively.
(cherry picked from commit c7a4eb4602)
Fix searching for samples by thread name, in particular, when there
are unnamed threads.
Use GtkMenuButton, instead of GtkButton, for the find-samples
header button.
Add mnemonics to the find-samples popover.

performance-log-viewer.py is a viewer for GIMP performance logs.
The viewer is made up of two parts: a sample-selection area at the
top, and an information area at the bottom.
The sample-selection area visualizes the sampled variables and
markers using a simultaneous set of plots, and displays the
currently selected samples. Samples can be selected directly
through the sample-selection area, or by other means, such as
searching for all samples satisfying a certain condition, or
containing a certain function.
The information area shows global information stored in the log, as
well as information specific to the currently selected samples,
including variable listing and statistics, full backtrace, and
profile/call-graph information.
Note that performance-log-viewer.py takes its input from STDIN,
like the rest of the performance-log tools, and is therefore
suitable for use as part of a pipeline. For standalone use, the
performance-log-viewer driver is also included, which takes the log
file as a command-line argument, and processes it through an
appropriate pipeline before feeding it to the viewer.
