ubb-la/gui.c: move sample retrieval to new function get_sample
...
Better than open-coding this non-trivial formula over and over again.

ubb-la/gui.c (si_text): used fixed %7.3f format if we have 7 characters
...
The variable number of digits was more confusing than useful. A drawback
is we may no longer see single-sample time changes when near the end of
the buffer.

ubb-la/gui.c (gui): the upper bound for "pos" is nibbles-skip-1, not "nibbles"

ubb-la/gui.c (show_map): fix calculation of middle point
...
Also here, we need to take into account that "pos" is zero-based.

ubb-la/gui.c (show_buffer): fix calculation of the position offset (dp)
...
"pos" counts from zero so the middle point is (nibbles-skip)/2 while
the code assumed "pos" was an index into the actual buffer and the
middle point would therefore have been (nibbles+skip)/2

ubb-la/gui.c (show_map): keep view rectangle size constant
...
Before, we had rounding effects that could make the rectangle width vary by
one pixel, depending on position.

ubb-la/gui.c (textf): use vsnprintf+valloca instead of vasprintf
...
This way, we don't malloc/free all the time, which could lead to more
memory fragmentation than alloca at roughly the same stack location.
