1ea584377e A significant number of our tests in C accidentally use functions
without prototypes. This patch converts the function signatures to have
a prototype for the situations where the test is not specific to K&R C
declarations. e.g.,

  void func();

becomes

  void func(void);

This is the ninth batch of tests being updated (there are a
significant number of other tests left to be updated).

9e02f58780 [analyzer] Highlight arrows for currently selected event
In some cases, when the execution path of the diagnostic
goes back and forth, arrows can overlap and create a mess.
Dimming arrows that are not relevant at the moment, solves this issue.
They are still visible, but don't draw too much attention.

97bcafa28d [analyzer] Add control flow arrows to the analyzer's HTML reports
This commit adds a very first version of this feature.
It is off by default and has to be turned on by checking the
corresponding box.  For this reason, HTML reports still keep
control notes (aka grey bubbles).

Further on, we plan on attaching arrows to events and having all arrows
not related to a currently selected event barely visible.  This will
help with reports where control flow goes back and forth (eg in loops).
Right now, it can get pretty crammed with all the arrows.

80e4ba24b9 [analyzer] Consider switch- and goto- labels when constructing the set of executed lines
When viewing the report in the collapsed mode the label signifying where
did the execution go is often necessary for properly understanding the
context.

a5ddd3cacb [analyzer] support a mode to only show relevant lines in HTML diagnostics
HTML diagnostics can be an overwhelming blob of pages of code.
This patch adds a checkbox which filters this list down to only the
lines *relevant* to the counterexample by e.g. skipping branches which
analyzer has assumed to be infeasible at a time.

The resulting amount of output is much smaller, and often fits on one
screen, and also provides a much more readable diagnostics.
