6bbc5b3730 Enhance fuzzcheck so that it understand the sqlite3_db_config() and 
optimization settings from unused bits in the database header, which
dbsqlfuzz is now using.

7520116441 Simplify a memcpy() in defragmentPage(). It now might copy more content than 
is strictly necessary, but runs faster and uses less code space.  Possible
reasons for the improved performance:
(1) the copy is now always 8-byte aligned,
(2) fewer intermediate results are required which means less register
pressure which helps the compiler to optimize the subroutine.

39a7a1a9be If the filename argument to sqlite3_load_extension() is an empty string, then 
raise an error.  It turns out that if dlopen() is called with an empty
filename, it tries to load the current executable.  And then if the caller
requests some other function from the current executable, mischief can result.
