/*
    Synopsis:   Searches for a pattern within a string or block of memory
                using a variant of the Boyer-Moore algorithm (improved by
                Horspool and Sunday). As fast or faster than the normal
                Boyer-Moore algorithm for most search strings, and much
                simpler.  Includes a basic function for searching blocks of
                memory with known sizes, plus an envelope that searches
                null-delimited strings.  Provides the option of repeatedly
                searching for the same pattern without re-parsing the pattern
                each time.  Original algorithm published by BOYER, R., and S.

                Fast Searching in Strings." Software - Practice and Experience,

                Technical Report No. 156.  Implemented in C by P. Hintjens.

                strfind_r() and memfind_r(), are reentrant versions of
                strfind() and memfind() for single searches, and
                strfind_rb() and memfind_rb() are reentrant versions of
                strfind() and memfind() supporting repeat searches against
                the same pattern.
