This avoids an unused and misleading assignment that might make
someone think the incremented variable will be used again.

Whenever softwrap was toggled on or line numbers were toggled on/off or
the window was resized, the extra rows per line needed to be recomputed
for ALL the lines. For large files with many long lines this was too
costly.
(This change causes the indicator to have an incorrect size when there
are many softwrapped chunks onscreen, but that will be addressed later.)
This fixes https://savannah.gnu.org/bugs/?60429.
Problem existed since version 5.0, since the indicator was introduced.
Those casts are redundant, and sometimes ugly. And as the types of
variables are extremely unlikely to change any more at this point,
the protection they offer against miscompilations is moot.

The make_new_node() function initializes 'extrarows' to a bad value
on purpose, to catch cases like this one where it doesn't get updated
properly.

Bug existed since version 5.0, since the indicator was introduced.
When compiling with GCC 10.1.0 and -O2 -Wall, the strncpy() call
in measured_copy() produced two stringop-truncation warnings.

This means that in most cases mark_is_before_cursor() is called twice:
once before get_region() is called, and once by get_region() itself.
This small duplication of effort is acceptable: the affected functions
are not time critical, and it makes the code shorter.
After the previous change, all remaining calls of parse_mbchar() have
NULL as their third parameter. So, drop that parameter and remove the
chunk of code that handles it. Also rename the function, as there are
already too many functions that start with "parse".
If the rest of nano is correct, then these checks are superfluous and
only slow the loops down. But if there is some incorrect code, then
let nano crash on dereferencing NULL so we can find and fix the bug.
No one ever reported seeing the message that was removed in commit
c039aaad one month ago, so most likely the code is correct and nano
never calls line_from_number() with a non-existent line number.
In this way, for single-width characters, one can see what character is
ahead of the cursor before actually moving the cursor to that position,
and, for double-width characters, the cursor never sits on a placeholder
but always shows the character that is actually there.
This addresses https://savannah.gnu.org/bugs/?55716.
