Changes since 1.10: +5 -31 lines 

Untimely spring cleaning:
* Garbage collect useless hand-rolled lookup tables.
* Merge one-line helper functions into callers.
* Garbage collect obfuscating macros.
* Fix one format string error (%d used for u_int).
* Garbage collect setlocale(3) and <locale.h>.
* Garbage collect several unused constants.
* Minus 45 LOC, no functional change.

As noticed by tedu@, the lookup table "table" was used uninitialized.
But since it was only used as a pre-matching optimization and the real
string comparison is done further down the line, that bug probably did
not cause wrong results but merely ruined -i performance.

Code review triggered by a naive question from Jan Stary.
