672f07c642 Fix the sqlite3_hard_heap_limit() so that it works with sqlite3_realloc64() 
in addition to sqlite3_malloc64().  Improvements to OOM processing and
debugging aids in the fuzzcheck utility.

d924e7bc78 Use the sqlite3Realloc() interface internally, rather than the public 
sqlite3_realloc64() equivalent, to avoid unnecessary calls to
sqlite3_initialize().

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

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.
