misc fixes (#69)
* Add a test for german case folding.

* Add a function to copy a string with a string with a larger allocation
  (to be used by the case folding routines)
* Add printf attributes to the printf-like functions and fix one format
  warning
* Cleanup the tempfree macro
* make more functions static
* rename fp to frp (FRame Pointer) to avoid shadowing with fp (File Pointer).
* add more const
* fix indent in UPLUS case
* add locale-aware case folding
* make nfiles size_t
* fix bugs in file closing:
    - compare fclose to EOF and pclose to -1
    - use nfiles instead of FOPEN_MAX in closeall
    - don't close files we did not open (0,1,2) fpurge/fflush instead

* - use NUL instead of 0 for char comparisons
- add ISWS() macro
- use continue; instead of ;

* Check for existance of the german locale before using it.

* Add missing parentheses, thanks Arnold.

Use MB_LEN_MAX instead of MB_CUR_MAX to avoid VLA (#70)
MB_CUR_MAX is the maximum number of bytes in a multibyte character
for the current locale, and might not be a constant expression.
MB_LEN_MAX is the maximum number of bytes in a multibyte character
for any locale, and always expands to a constant-expression.

fed1a562c3 Make I/O errors fatal instead of mere warnings (#63)
An input/output error indicates a fatal condition, even if it
occurs when closing a file. Awk should not return success on I/O
error, but treat I/O errors as it already treats write errors.

Test case:

$ (trap '' PIPE; awk 'BEGIN { print "hi"; }'; echo "E $?" >&2) | :
awk: i/o error occurred while closing /dev/stdout
 source line number 1
E 2

The test case pipes a line into a dummy command that reads no
input, with SIGPIPE ignored so we rely on awk's own I/O checking.
No write error is detected, because the pipe is buffered; the
broken pipe is only detected as an I/O error on closing stdout.

Before this commit, "E 0" was printed (indicating status 0/success)
because an I/O error merely produced a warning. A shell script
was unable to detect the I/O error using the exit status.

2976507cc1 rename T.concat to T.csconcat to avoid case-insensitive conflict (#64)
On case-insensitive file systems (i.e.: macOS), T.concat and
t.concat are the same file, so these conflicted. This commit
renames T.concat to avoid the conflict.

a96aebbbd6 Fix printf format conversions. (#59)
Further simplify printf % parsing by eating the length specifiers
during the copy phase, and substitute 'j' when finalizing the format.
Add some more tests for this.

ff5d67610c Fix printf formats for integers (#57)
* More cleanups:
- sprinkle const
- add a macro (setptr) that cheats const to temporarily NUL terminate strings
  remove casts from allocations
- use strdup instead of strlen+strcpy
- use x = malloc(sizeof(*x)) instead of x = malloc(sizeof(type of *x)))
- add -Wcast-qual (and casts through unitptr_t in the two macros we
  cheat (xfree, setptr)).

* More cleanups:
- add const
- use bounded sscanf
- use snprintf instead of sprintf

* More cleanup:
- use snprintf/strlcat instead of sprintf/strcat
- use %j instead of %l since we are casting to intmax_t/uintmax_t

* Merge the 3 copies of the code that evaluated array strings with separators
and convert them to keep track of lengths and use memcpy instead of strcat.

* Fix formats for 32 bit machines broken by previous commit.
We use intmax_t to provide maximum range for both 32 and 64 bit machines.
