Add NULL checks on all sqlite3_vfs_find(0) calls. This is not strictly

necessary. There are no vulnerabilities here. However, adding these
checks avoids unnecessary static analyzer complaints.

Add an optional function to the chsumvfs extension. When activated by
...
the SQLITE_CKSUMVFS_INIT_FUNCNAME macro, this function will invoke the
file-control that sets the number of reserved bytes to 8. This can be
used to initialize a cksumvfs database file by programming languages
that do not have access to the sqlite3_file_control() interface.
