Fix test_stat.c so that it does not cause compilation errors if SQLITE_OMIT_VIRTUALTABLE is defined. check-in: bf4fc088 user: dan tags: trunk

Fix makefiles so that they build sqlite3_analyzer again. Tweaks to comments in test_stat.c. Fix tclsqlite.c to build the sqlite3_analyzer again. check-in: e6cd1545 user: drh tags: trunk

In the async-IO module, do not increment the open file-counter until after an "open file" event has been added to the event queue. Otherwise, an OOM may cause the system to increment the counter even though no file was successfully opened. check-in: 15a190dc user: dan tags: trunk

/*
** Page paths:
** 
**   The value of the 'path' column describes the path taken from the 
**   root-node of the b-tree structure to each page. The value of the 
**   root-node path is '/'.
**
**   The value of the path for the left-most child page of the root of


**   a b-tree is '/000/'. The next to left-most child of the root page is
**   '/001', and so on, each sibling page identified by a 3-digit hex 
**   value. The children of the 450th left-most sibling have paths such
**   as '/1c2/000/, '/1c2/001/' etc.
**
**   Overflow pages are specified by appending a '+' character and a 
**   six-digit hexadecimal value to the path to the cell they are linked
**   from. For example, the three overflow pages in a chain linked from 
**   the left-most cell of the 450th child of the root page are identified
**   by the paths:
................................................................................
**      '/1c2/000+000001'         // Second page in overflow chain
**      '/1c2/000+000002'         // Third page in overflow chain
**
**   If the paths are sorted using the BINARY collation sequence, then
**   the overflow pages associated with a cell will appear earlier in the
**   sort-order than its child page:
**
**      '/1c2/000/'               // Left-most child of 450th child of root

/*
** Page paths:
** 
**   The value of the 'path' column describes the path taken from the 
**   root-node of the b-tree structure to each page. The value of the 
**   root-node path is '/'.
**
**   The value of the path for the left-most child page of the root of
**   a b-tree is '/000/'. (Btrees store content ordered from left to right
**   so the pages to the left have smaller keys than the pages to the right.)
**   The next to left-most child of the root page is
**   '/001', and so on, each sibling page identified by a 3-digit hex 
**   value. The children of the 451st left-most sibling have paths such
**   as '/1c2/000/, '/1c2/001/' etc.
**
**   Overflow pages are specified by appending a '+' character and a 
**   six-digit hexadecimal value to the path to the cell they are linked
**   from. For example, the three overflow pages in a chain linked from 
**   the left-most cell of the 450th child of the root page are identified
**   by the paths:
................................................................................
**      '/1c2/000+000001'         // Second page in overflow chain
**      '/1c2/000+000002'         // Third page in overflow chain
**
**   If the paths are sorted using the BINARY collation sequence, then
**   the overflow pages associated with a cell will appear earlier in the
**   sort-order than its child page:
**
**      '/1c2/000/'               // Left-most child of 451st child of root
