c595419910 Minor changes to make some newer test cases work under more compile-time 
options.

dfcfff646a During fuzz testing with the fuzzcheck utility program, impose a record 
length limit of 100MB and a limit on the length of LIKE strings of 50 bytes.

9cc5b4eeb5 Remove an incorrect ALWAYS() macro from balance_nonroot(), which could result 
in corrupt databases if it were optimized out.  This ALWAYS was added 
only two weeks ago (check-in [f9f2e23bbd68a]) and has never appeared in an
official release.

6a5a4208fc Combine the implementations of the ".tables" and ".indexes" commands in the 
command-line shell.  The ".indexes" command now puts the indexes in multiple
columns, just like ".tables" and shows all indexes in all attached databases.
