* WT-2661: Coverity failures: 1356050-1356053
CID 1356050: (NULL_RETURNS)
Dereferencing a pointer that might be null "opts->home" when calling "snprintf".
CID 1356050: (NULL_RETURNS)
Dereferencing a pointer that might be null "opts->uri" when calling "snprintf".
* Assigning address of auto variable '_opts' to static (it's an auto
variable in main(), so it's safe, but make lint happy).
* Coverity appears to be confused by argv handling and eventually passing
NULL to snprintf.
2. var_assign_alias: Assigning: opts->progname = argv[0]. Both
are now tainted.
47. vararg_transitive: Call to snprintf with tainted argument
opts->progname taints NULL.
48. tainted_data_sink_lv_call: Passing tainted variable 0UL to
tainted data sink snprintf.
NULL is tainted? I'm hoping that using a strlen() call to figure out the
string length instead of snprintf() will make this one go away.
* test_wt2246_col_append wasn't actually doing any work, set nrecords to
a 20 million default.
* KNF
* Don't use "inline" in example programs, it requires Windows #ifdef's.
