closes#8274
The parent commit tries a different approach, but that fails on Apple
Clang version:
Apple LLVM version 10.0.0 (clang-1000.11.45.5)
Target: x86_64-apple-darwin17.7.0
which somehow compiles the check_c_source_compiles() check, but then
complains during later compilation that __fpclassify is not defined
(regardless of "#include <math.h>").
Problem: When making a character lower case with tolower() changes the byte
cound, it is not made lower case.
Solution: Add strlow_save(). (Dominique Pelle, closesvim/vim#1406)
cc5b22b3bf
Join almost identical strup_save and strlow_save functions to one
Function.
Removes dead code (enc_utf8, enc_dbcs and has_mbyte now have hardcoded values),
relies on libc implementation being more optimized. Also where previously
negative character just would never be found it is an assertion error now.

Problem: printf() test fails on Windows. "-inf" is not used.
Solution: Check for Windows-specific values for "nan". Add sign to "inf"
when appropriate.

This looks mostly like a case where the compiler that ships with Ubuntu
12.04 has gone a little too far: `fmt_spec` is actually a char, as are
the literals, so there's really no issue.
Problem: printf() gives an error when the argument for %s is not a string.
(Ozaki Kiichi)
Solution: Behave like invoking string() on the argument. (Ken Takata)

Note: This does not remove some intentional legacy usages of strncpy.
- memcpy isn't equivalent because it doesn't check the string
length of `src`, and doesn't zero-out the remainder of `dst`.
- xstrlcpy isn't equivalent because it doesn't zero-out the
remainder of `dst`. Some Vim logic depends on that (e.g.
ex_append which calls vim_strnsave).

Problem: Searching for a character matches an illegal byte and causes
invalid memory access. (Dominique Pelle)
Solution: Do not match an invalid byte when search for a character in a
string. Fix equivalence classes using negative numbers, which
result in illegal bytes.
