** FTS maintains a separate indexes for each language-id (a 32-bit integer).
** Within each language id, a separate index is maintained to store the
** document terms, and each configured prefix size (configured the FTS 
** "prefix=" option). And each index consists of multiple levels ("relative
** levels").
**
** All three of these values (the language id, the specific index and the
** level within the index) are encoded in 64-bit integer values stored
** in the %_segdir table on disk. This function is used to convert three
** separate component values into the single 64-bit integer value that
** can be used to query the %_segdir table.
**
** Specifically, each language-id/index combination is allocated 1024 
** 64-bit integer level values ("absolute levels"). The main terms index
** for language-id 0 is allocate values 0-1023. The first prefix index
** (if any) for language-id 0 is allocated values 1024-2047. And so on.
** Language 1 indexes are allocated immediately following language 0.
**
** So, for a system with nPrefix prefix indexes configured, the block of
** absolute levels that corresponds to language-id iLangid and index 
** iIndex starts at absolute level ((iLangid * (nPrefix+1) + iIndex) * 1024).
