79d5bc80c7 Enhance PRAGMA function_list so that it shows all instances of each FuncDef, 
the number of arguments, the encoding, the type, and the flags.  Use this
capability to locate and fix incorrect function flags in the standard build.

0cbec59c8b When generating the name of a view (or common table expression) because the 
SQL does not specify a name, avoid the names "true" and "false" which might
be confused for the boolean literals of the same name, leading to an
inconsistent abstract syntax tree.

cbb9da337e Work toward reducing the incremental size of an ExprList object to 24-byte 
per entry, from 32-bytes (on a 64-bit machine).  This helps the new
mini-lookaside allocator to run better by avoiding excessive reallocs.
The current change mostly works, but still has a few loose ends to tie up.
This check-in is merely a snapshot to save my work.
