Neil Horman 0981c20f8e Fix NULL pointer deref when parsing the stable section
When parsing the stable section of a config such as this:
openssl_conf = openssl_init
[openssl_init]
stbl_section = mstbl
[mstbl]
id-tc26 = min

Can lead to a SIGSEGV, as the parsing code doesnt recognize min as a
proper section name without a trailing colon to associate it with a
value.  As a result the stack of configuration values has an entry with
a null value in it, which leads to the SIGSEGV in do_tcreate when we
attempt to pass NULL to strtoul.

Fix it by skipping any entry in the config name/value list that has a
null value, prior to passing it to stroul
