The function strbuf_add_wrapped_text takes a NUL-terminated
string. This makes it annoying to wrap strings we have as a
pointer and a length.
Refactoring strbuf_add_wrapped_text and all of its
sub-functions to handle fixed-length strings turned out to
be really ugly. So this implementation is lame; it just
strdups the text and operates on the NUL-terminated version.
This should be fine as the strings we are wrapping are
generally pretty short. If it becomes a problem, we can
optimize later.

strbuf_add_wrapped_text() is called only from print_wrapped_text()
without a strbuf (in which case it writes its results to stdout).
At its only callsite, supply a strbuf, call strbuf_add_wrapped_text()
directly and remove the wrapper function.

The newly added function can rewrap text according to a given first-line
indent, other-indent and text width.

I'm about to use this pattern more than once, so make it a common function.

The original interface assumed that the input string is
always terminated with a NUL, but that wasn't too useful.

utf8_width() function was doing two different things. To pick a
valid character from UTF-8 stream, and compute the display width of
that character. This splits the former to a separate function
pick_one_utf8_char().

Now, it returns the current column, does not add a newline, and you can
pass a negative indent, to indicate that the indent was already printed.
With this, you can actually continue in the middle of a paragraph, not
having to print everything into a buffer first.

People can spell config.commitencoding differently from what we
internally have ("utf-8") to mean UTF-8. Try to accept them and
treat them equally.

Introduce is_utf() to check if a text looks like it is encoded
in UTF-8, utf8_width() to count display width, and implements
print_wrapped_text() using them.
git-commit-tree warns if the commit message does not minimally
conform to the UTF-8 encoding when i18n.commitencoding is either
unset, or set to "utf-8".
