Sergio Carlavilla Delgado 989d921f5d Migrate doc to Hugo/AsciiDoctor 
I'm very pleased to announce the release of
our new website and documentation using
the new toolchain with Hugo and AsciiDoctor.

To get more information about the new toolchain
please read the FreeBSD Documentation Project Primer[1],
Hugo docs[2] and AsciiDoctor docs[3].

+******************************************************************************
+**
+** This file contains an implementation of two eponymous virtual tables,
+** "sqlite_dbdata" and "sqlite_dbptr". Both modules require that the
+** "sqlite_dbpage" eponymous virtual table be available.
+**
+** SQLITE_DBDATA:
+** sqlite_dbdata is used to extract data directly from a database b-tree
+** page and its associated overflow pages, bypassing the b-tree layer.
+** The table schema is equivalent to:
+**
+** CREATE TABLE sqlite_dbdata(
+** pgno INTEGER,
+** cell INTEGER,
+** field INTEGER,
+** value ANY,
+** schema TEXT HIDDEN
+** );
+**
+** IMPORTANT: THE VIRTUAL TABLE SCHEMA ABOVE IS SUBJECT TO CHANGE. IN THE
+** FUTURE NEW NON-HIDDEN COLUMNS MAY BE ADDED BETWEEN "value" AND
+** "schema".
+**
+** Each page of the database is inspected. If it cannot be interpreted as
+** a b-tree page, or if it is a b-tree page containing 0 entries, the
+** sqlite_dbdata table contains no rows for that page. Otherwise, the
+** table contains one row for each field in the record associated with
+** each cell on the page. For intkey b-trees, the key value is stored in
+** field -1.
+**
+** For example, for the database:
+**
+** CREATE TABLE t1(a, b); -- root page is page 2
+** INSERT INTO t1(rowid, a, b) VALUES(5, 'v', 'five');
+** INSERT INTO t1(rowid, a, b) VALUES(10, 'x', 'ten');
+**
+** the sqlite_dbdata table contains, as well as from entries related to
+** page 1, content equivalent to:
+**
+** INSERT INTO sqlite_dbdata(pgno, cell, field, value) VALUES
+** (2, 0, -1, 5 ),
+** (2, 0, 0, 'v' ),
+** (2, 0, 1, 'five'),
+** (2, 1, -1, 10 ),
+** (2, 1, 0, 'x' ),
+** (2, 1, 1, 'ten' );
+**
+** If database corruption is encountered, this module does not report an
+** error. Instead, it attempts to extract as much data as possible and
+** ignores the corruption.
+**
+** SQLITE_DBPTR:
+** The sqlite_dbptr table has the following schema:
+**
+** CREATE TABLE sqlite_dbptr(
+** pgno INTEGER,
+** child INTEGER,
+** schema TEXT HIDDEN
+** );
+**
+** It contains one entry for each b-tree pointer between a parent and
+** child page in the database.

** is shared by multiple database connections. Therefore, while parsing
** schema information, the Lookaside.bEnabled flag is cleared so that
** lookaside allocations are not used to construct the schema objects.
+**
+** New lookaside allocations are only allowed if bDisable==0. When
+** bDisable is greater than zero, sz is set to zero which effectively
+** disables lookaside without adding a new test for the bDisable flag
+** in a performance-critical path. sz should be set by to szTrue whenever
+** bDisable changes back to zero.
+**
+** Lookaside buffers are initially held on the pInit list. As they are
+** used and freed, they are added back to the pFree list. New allocations
+** come off of pFree first, then pInit as a fallback. This dual-list
+** allows use to compute a high-water mark - the maximum number of allocations
+** outstanding at any point in the past - by subtracting the number of
+** allocations on the pInit list from the total number of allocations.
+**
+** Enhancement on 2019-12-12: Two-size-lookaside
+** The default lookaside configuration is 100 slots of 1200 bytes each.
+** The larger slot sizes are important for performance, but they waste
+** a lot of space, as most lookaside allocations are less than 128 bytes.
+** The two-size-lookaside enhancement breaks up the lookaside allocation
+** into two pools: One of 128-byte slots and the other of the default size
+** (1200-byte) slots. Allocations are filled from the small-pool first,
+** failing over to the full-size pool if that does not work. Thus more
+** lookaside slots are available while also using less memory.
+** This enhancement can be omitted by compiling with
+** SQLITE_OMIT_TWOSIZE_LOOKASIDE.
