226352afcb build: Fix -Wconversion warnings for fpclassify et al 
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>").

c6a039d087 build: Fix -Wconversion warnings for fpclassify et al 
closes #8274

- Instead of #undef and re-#define, define "xfoo" wrappers to avoid
  include-order sensitivity.
- The warnings are bogus, caused by bad interaction between glibc and
  clang 6+.

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, closes vim/vim#1406)

Join almost identical strup_save and strlow_save functions to one
Function.

19044a15f9 strings: Replace vim_strchr implementation with a saner one 
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.

c6b3975774 vim_vsnprintf: fix conversion error #6311 
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.

59fd0c4132 refactor: Remove strncpy/STRNCPY. (#6008) 
Closes #731
References #851

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).
