3 more fixes (#75)
* LC_NUMERIC radix issue.

According to https://pubs.opengroup.org/onlinepubs/7990989775/xcu/awk.html
The period character is the character recognized in processing awk
programs.  Make it so that during output we also print the period
character, since this is what other awk implementations do, and it
makes sense from an interoperability point of view.

* print "T.builtin" in the error message

* Fix backslash continuation line handling.

* Keep track of RS processing so we apply the regex properly only once
per record.

argument parsing cleanups, dynamic program file allocation, fpe error enhancement. (#72)
* - enhance fpe handler to print the error type
- cleanup argument parsing
- dynamically allocate program filename array

* bison uses enums now, not #define's, make it work with that.

* We need to use either the enums or the defines but not both. This
is because bison -y will create both enums and #defines, while bison
without -y produces only the enums, and byacc produces just #defines.

* fix indentation

* Set the tokentype when we have a match in the scan, and reset it later
when we decide that the match was bad. Fixes nbyacc.

* - don't use pattern rules for portability
- try to move both flavors of generated names for portability

* Amend tests for the new error messages

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.

0d8778bbbb more cleanups (#55)
* 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.
