ce11e1f195 Add section for laces in lowerrune and upperrune and more ranges
This is a special third kind of structure found in Unicode, besides
singletons and ranges.
This dramatically reduces the number of explicit singletons in the
lookup tables.
Also, I changed the awk-script so that it can sort trivial
translations as well, breaking down the LOC even more.

The binary size of tr dropped from 67K to 51K.

9565eef895 Refactor uppercase-inclusion in libutf
Previously, the to*rune function would have to jiggle with two
arrays, and it somehow evaded me that it is actually way simpler
to just add another entry to the arrays if needed.
Binary size goes slightly down, e.g. tr statically linked against
musl: 68072 -> 67688

Behind the scenes though the conversion should be a bit faster and,
more importantly, the scary case-conversion function is simplified
and easier to understand.

It also drops nearly half the LOC in upperrune.c and lowerrune.c.

73577f10a0 Scrap chartorunearr(), introducing utftorunestr()
Interface and function as proposed by cls.

The reasoning behind this function is that cls expressed his
interest to keep memory allocation out of libutf, which is a
very good motive.
This simplifies the function a lot and should also increase the
speed a bit, but the most important factor here is that there's
no malloc anywhere in libutf, making it a lot smaller and more
robust with a smaller attack-surface.

Look at the paste(1) and tr(1) changes for an idiomatic way to
allocate the right amount of space for the Rune-array.

a5ae899a48 Scrap readrune(), introducing fgetrune()
Interface as proposed by cls, but internally rewritten after a few
considerations.
The code is much shorter and to the point, aligning itself with other
standard functions. It should also be much faster, which is not bad.

f9846a9a6b Split up is*rune() and to*rune() functions into individual source files
This optimizes the binary size for each tool that uses these functions.
Previously, if a program just used one single function, maybe even a
one-liner, it would statically compile in all lookup-tables, bloating
the binary by up to 20K.
All these changes are derived from a local libutf where I do the
primary changes. So I hope that I can merge these things into libutf
sooner or later, as discussed on the ml.

02ec321419 Add missing is*rune() functions and tolowerrune() and toupperrune()
This basically means that we now have an autogenerating typecheck
and case-conversion tool.
Don't freak out when you see the added LOC. Given we now have
an additional mapping to the uppercase-characters, some ranges got
"lost" and have to be written literally by the generating awk-script.

The runetypebody.h was generated by myself using my modified version
of mkrunetype.awk and I'll push the changed version as soon as this
has been discussed on the ml.
If you worry about speed, consider, that bsearch is just the right
tool for this job and can even handle a long array like this.

66a5ea722d getlines: last line of file should always have a newline
This is a useful behavior if you want to reorder the lines,
because otherwise you might end up with originally two lines
on one, e.g.

	$ echo -ne "foo\nbar" | sort
	barfoo
