/* Initialization of noise-words hashtable from noise.txt

File noise.txt should be in the server's working directory.
It consists of control lines and text lines.

Text line is just a string of one or more words to be declared as noise.
Please keep them shorter than 1000 characters.

Control lines are those started from "Language:" or "Encoding:" (case is important)
"Language: lang-id" tells to use rules for language "lang-id" for future text
lines, until either another "Language:" control line or end of file.
Similarly, "Encoding: enc-id" tells to use rules for encoding "enc-id".
Control lines are always in plain ASCII, no matter which encoding is active
for text lines.
By default, server default language and "UTF-8" encoding will be used.

Noise words seem to be case-insensitive, but it is not true. If you
enter a word in text line, up to four noise words will be registered:
the word exactly as it was entered;
an uppercased form of this word, if it is defined for active language;
an lowercased form of this word, if it is defined for active language;
a capitalized form, with one (or more) first chars in upper case and the rest in lower case.
*/

/* When we use language handlers to split text lines on (noise) words, they
may try to access to lh_noise_words. Bugs will occur if this table will be
filled during the scan: some word may be filtered out as noise before all
four forms will be stored. To avoid this, temporary table will be filled;
meanwhile dummy (= empty) hashtable will be used to provide valid non-NULL
pointer for language-specific callbacks. */
