This module is unbreakable (when called with correct module name
and function name). Every imaginable input from the caller and
from the imported module "loaddata-tbllingvoj" will output either
a useful result or at least the string "Grava eraro".

Cxi tiu modulo estas nerompebla (kiam vokita kun gxustaj nomo de modulo

The function of this module is governed by
the "Specification of the 2-dimensional table picking system".
* y-index markers are obligatory and
  lowercase (numbers and "-" not yet allowed)  !!!FIXME!!!
* x-index markers are disallowed

Note that the table T77 we use is NOT pluprocessed before, thus me must
strip RLLR ourselves, and both /cy/ and /c0/ are included (see below).

Status codes from submodule:
* #E00: OK
* #E01: internal
* #E02: template not found
* #E03 ... #E79: preprocessing error, range reserved by the specification

Column numbering in the source table:
* numbering starts from ZERO
* /cy/ does not count (it has theoretically index "-1")
* note that there is no comma between columns /cy/ and /c0/
* "loaddata-tbllingvoj" T77 returns the complete table line including
  the y-index marker /cy/, this means that unless the /cy/ part is
  trimmed off before, index ZERO fed into "lfhsplittotable" will
  return both /cy/ and /c0/, thus the indexes are NOT be OFF-by-ONE

Structure of a row in the source table with 1+11 columns:
- /cy/ : y-index marker (2 or 3 digits)  !!!FIXME!!! soon even more
- /c0/ : name of the language in the site language
         * EO: usually AJ lowercase, alternatively SB beginning
               with uppercase letter
         * ID: without "bahasa " and beginning with uppercase letter
- /c1/ : QID (for example "Q5432") "Q" + 2...8 digits, earliest digit
         only "1"..."9", further digits "0"..."9"
- /c2/ : name of the language in the language itself
         ("propralingve") (may be RLLR-enclosed)
- /c3/ : constructed and antique status (digit "0"..."3")
- /c4/ : ISO 639-1:2002 2-letter code (only lowercase)
- /c5/ : ISO 639-3:2007 3-letter code (only lowercase)
- /c6/ : wiki access code, itself usually same as /cy/, but may be different
         and longer up to 10 char:s, for example "zh-min-nan", leave it "-"
         here if code is same or unknown, use "??" if code belongs to
         other language ("als.pedia.org")
- /c7/ : wiki availability code (2 digits "0"..."2" ie "00"..."22"),
         "-" causes reddish background and no info about availability
- c8 : name of ipedia article, base principle usually
       followed (there are some exceptions):
       - EO: core word usually AJ name with uppercased begin
             followed by " lingvo", no "la" article
       - ID: prefixed by "Bahasa " and core word begins with uppercase letter
- c9 : category with our site language ("eo" or "id") in other tionary
       (with category NS prefix, but without language prefix, without "]]"
       or other nonsense (may be RLLR-enclosed), can be absurdly long
       "Rummad:Wikeriadur:Distagaduriou' a vank en indonezeg" has 52
       octet:s and even worse 2 colons and one apo)
- ca : number of pages in that category, apo:s ("16'384") are
       tolerable (this cannot be peeked automatically)
Note that /cy/ and /c0/ are ultimately obligatory, the remaining
ones are only highly desirable.

Overall structure of the generated page:
* top either big fatal block or tiny success block, both with purge link
* huge destination table (not if fatal error)
* technical summary block (no links inside) (may be omitted in some cases)
* bottom either big fatal block or tiny success block, both with purge link

Structure of a row in the destination table with 14 columns:
- /d00/ : * index (in brackets, not bold)
          * space
          * language access code (bold) (literally peeked from /cy/
            y-index marker in the source table)
          # adjust background for "eo" only
- /d01/ : * name of the language in the site language with link to the
            lemma page (name literally peeked from /c0/ in the source table,
            must be available and valid, link augmented by "lfiultpl5repl"
            according to control string "contabpages[0]")
- /d02/ : - QID (for example "Q5432")  !!!FIXME!!! not yet used
- /d03/ : - name of the language in the language itself
            (literally peeked from /c1/ in the source table)
- d04 : - constructed and antique status (expanded from digit "0"..."3"
          peeked from /c2/ in the source table)
        # adjust background to greenish or grey if applicable
- d05 : - "ISO 639-1:2002" 2-letter language code
          (literally peeked from "c3" in the source table)
- d06 : - "ISO 639-3:2007" 3-letter language code
          (literally peeked from /c4/ in the source table)
- d07 : - ? link to the "tln" top lng category in own tionary if
            desired, no page count here
        - ? EOL (only if both cat:s are desired)
        - ? link to the "kap" category in own tionary with all words in
            the language (constructed from constant string "strpikkatns"
            (category namespace prefix without ":") and /c0/ augmented by
            "lfiultpl5repl" according to control string "contabpages[6]")
          - ? EOL (if complaint below exists)
          - ? complaint about not existing if applicable
          - ? EOL (if the "parent" link to the "kap" category is present)
          - ? number of pages (queried) or "??" if querying does not work
        # adjust background to reddish if the category (one of two)
          does not exist
        ! depends on variables "bootlnsow" and "bootlnexp" and "bookapsow"
          and "bookapexp" and includes expensive querying (2), column
          can be completely hidden by "bood07"

          does not exist
        ! depends on variables "boovorsow" and "boovorexp" and "boomalsow"
          and "boomalexp" and includes expensive querying (2), column
          can be completely hidden by "bood08"
- d09 : - link to the appendix page (constructed from constant string
          "strpikapxns" (appendix namespace prefix without ":") and /c0/
          augmented by "lfiultpl5repl" according to control string
          "contabpages[1]") controlled by "booapxsow"
        - EOL (only if both pages are desired)
        - link to the index page in own tionary with
          the language (constructed from constant string "strpikindns"
          (index namespace prefix without ":") and /c0/ augmented by

        # adjust background to reddish if at least one of them does not exist
        ! depends on variables "booapxsow" and "booapxexp" and "booindsow"
          and "booindexp" and includes expensive querying (1), column
          can be completely hidden by "bood09"
- d10 : - quasi-external link to wikipedia in the language concerned
          (constructed from "c5" and "c6" and /cy/, irrespective availability)
        - EOL (if note below exists)
        - note about bad availability of the wiki if applicable
        # adjust background to grey according to bad availability
        ! no expensive querying here
- d11 : - quasi-external link to tionary in the language concerned
          (constructed from "c5" and "c6" and /cy/, irrespective availability)
        - EOL (if note below exists)
        - note about bad availability of the wiki if applicable
        # adjust background to grey according to bad availability
        ! no expensive querying here
        & special rule ie blocking for own site language
- d12 : - quasi-external link to the article in own ipedia about the language
          (article name constructed from /c8/, or alternatively if /c8/ is
          not available then it is guessed using "lfiultpl5repl" from /c0/
          and "contabpages[7]" and " (??)" is added)
        # adjust background to reddish if /c8/ is not available
        ! no expensive querying here
- d13 : - quasi-external link to EO or ID category in the tionary in the
          language concerned (peeked from "c8" in the source table)
        - EOL (if number of articles below exists)
        - number of articles (peeked from "c9" in the source table)
        # adjust background to reddish if "c8" or "c9" is not available
        ! no expensive querying here
        & special rule ie blocking for own site language

Expensive querying:
There are up to 6 expensive queries (2 cat:s plus appendix plus index, one
cat costs 2 bucks (separate "ifexist" and "pagesincategory") per page,
appendix and index cost one buck per page) per language and thus table row.
This is a big problem in "mkomtbllin" but in "msngtbllin" it is no problem
at all. The hard limit set by wiki software is 500. The totally fired number
of calls can be reduced via parameters "bootlnexp" "bookapexp" "boovorexp"
"boomalexp" "booapxexp" "booindexp" and "numproba". We even have a
fraud implemented.

Error handling:
- #E08 if argument supplied from the caller is bad, output is minimal with
  huge error, no huge table and no technical summary block, fatal warning
  YES, position_err is NOT valid
- if early syntax check fails (line ZERO is not site lang) output is minimal
  with huge error "#E01 Grava eraro" then, no huge table and no summary,
  fatal warning YES, position_err is valid (can be ZERO or equal "numtblend")
- "boosinerr" set to true in a table row, the row is completed (risk
  for "-"), loop exited and table closed, huge error
  "#E37 Sintaksa eraro" is outside the table, summary YES, fatal warning YES
- "numeertru" (no bool) incremented for every truncated line in source table
  having /cy/ and /c0/, minimal error "Nekompleta linio" is in the table
  element at column 0, do not exit the loop, fatal warning NO
- "numeertlo" (no bool) incremented for every too long line in source table,
  lagom error "Tro longa (ele) linio" is in the table
  element at column 0, do not exit the loop, fatal warning YES
- "numerokec" (no bool) incremented for every minor
  error (possible in line ZERO), do not exit the loop, fatal warning NO
- "numeerkap" (no bool) incremented
- "numeermal" (no bool) incremented
- "numeerind" (no bool) incremented for every missing index page
  error (possible in line ZERO), do not exit the loop, fatal warning NO
- if "mw.title.getCurrentTitle().prefixedText" does not reveal our
  pagename (needed for purge link) then we don't whine but use a bad
  default "Special:Recent changes" instead

Errors codes in "numerr":
* #E01 -- internal
* #E02
* #E03
* #E08 -- number of anon param
* #E11 -- obviously invalid langcode from anon param {{{1}}} (only msng)
* #E12 -- unknown langcode from anon param {{{1}}} (only msng,
          only error showed inside table)
* #E13 -- anon param {{{1}}} boolean is bad (only big)
* #E14 -- anon param {{{2}}} integer is bad (only big)
* #E15 -- fatal (only msng)
* #E16 -- named param "infsel=" missing
