drh 23a885956e Add the SQLITE_CONFIG_MEMDB_MAXSIZE configuration option for configuring
the default maximum size of an in-memory database created using
sqlite3_deserialize().  This is necessary to make the interface reasonably
testable.

drh 6ca644818b Enhancements to deserialize: (1) Add the SQLITE_FCNTL_SIZE_LIMIT file control
to set a maximum size for an in-memory database, defaulting to 
SQLITE_MEMDB_DEFAULT_MAXSIZE or 1GiB.  (2) Honor the SQLITE_DESERIALIZE_READONLY
flag. (3) Enhance the TCL interface to support -maxsize N and -readonly BOOLEAN.
(4) Add the --maxsize option to the ".open" command and on the command-line for
the CLI.

dan 1ea0443c2d Add new sqlite3_prepare_v3() flag SQLITE_PREPARE_NO_VTAB, for preparing
statements that are not allowed to use any virtual tables. Use this to prevent
circular references in triggers on virtual table shadow tables from causing
resource leaks.

to identify potential shadow tables.  The SQLITE_PREPARE_SHADOW argument
to sqlite3_prepare_v3() is defined.  It is designed to permit writing to
shadow tables, but is currently an unused placeholder.
