473af4fe03 First draft of the complete dbdump.c library.

688633cb9e Infrastructure for an extension C-library to implement sqlite3_db_dump() and 
a corresponding "dbdump" command-line utility - both of which do the same
work as the ".dump" command of the CLI.

d3bb79bd0f In the output of the ".dump" command in the CLI, quote newline and 
carriage-return characters using the char() function, so that they do not
get eaten by end-of-line processing logic in the OS or in other command-line
utilities and/or libraries.

bbc0177460 In the OSSFuzz test module, invoke the progress handler much more frequently 
so that timeouts are detected punctually even if the test script is running
opcodes that individually take a long time (for example, an OP_Function opcode
that invokes "randomblob(1.5e6)").

f157d10f9f Improvements to ".selftest --init". Tests are number in increments of 10

in that it uses SHA3 hashing instead of SHA1, so the new is subtly 
incompatible with the old.
