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

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.

Also remove a redundant semicolon.

Also had to rebase on upstream pull.

cc165f4be9 maketab: support build systems with read-only source.
If your generated files are considered outputs that live elsewhere, you
need a way to tell maketab where ytab.h actually is.

Specifically, I'm trying to avoid checking in generated files in
Android's AOSP tree's copy of one-true-awk.
