Boris reported that 'perf top' is unusable on his default 'black on
white' terminal, which uses (eye friendly) light-grey as a background
color.
The reason is that the TUI cursor for the current selection line uses
HE_COLORSET_SELECTED, and that has a default background color of
'lightgrey' - which is a common terminal background choice and thus
the colors conflict.
Use yellow as the background color instead: that should be an uncommon
terminal background, yet it's still ergonomic on both black and
white/grey terminals.
[ It would be a better solution to straight out detect color
collisions and resolve them reasonably by converting them to RGB and
calculating color space distances, but I was unable to find
proper documentation for SLtt_get_color_object() to recover the
current color scheme so I gave up ... Yellow works well enough. ]

This shows map_groups__clone get the map twice and put it when
map_groups__exit.

Since hists__init doesn't set the destructor of hists_evsel (which is an
extended evsel structure), when hists_evsel is released, the extended
part of the hists_evsel is not deleted (note that the hists_evsel object
itself is freed).
This fixes it to add a destructor for hists__evsel and to set it up.

Since the __map_groups__insert got the given map, we don't need to keep
it. So put the maps.
Refcnt debugger shows that map_groups__fixup_overlappings() got a map
twice but the group released it just once. This pattern usually
indicates the leak happens in caller site.

The term functions are needed by help.c which is going to be moved into
a separate library. Move them out of util.c and into their own file.

perf_env__set_cmdline() only saves the arguments the first time it's
called. It doesn't need to be called every time the options and
suboptions are parsed. Instead it can just be called once.
This also has the advantage of making the option parsing code less
perf-specific so it can be moved out to a library.
