The functions dump of parameters only if they differ from the
defaults. The check for equality is rather coarse but it should work as
long as all core objects use C++ types correctly e.g. integer are not used
to store boolean values (I'm looking at you, enable_root and
localhost_match_wildcard_host). The boolean type has a specialization to
convert the value to the string format used for all defaults in the core.
This also adds the missing return value checks to the dprintf calls and
reports errors if any are encountered.
The ssl parameters were defined as strings even thought they were actually
enums. The events parameter was also a string even though it was an enum.
Also added the missing "all" value to the events enum. This fixes the
regression of scripts not being launched on all events by default.
Moved the definition of the default version string where it should be and
removed the empty value check.
The get_suffixed_size function is now exposed in the internal config
header and it also checks for the validity of the size types.
Took the new function into use and added the appropriate error messages.
Enabling it with a value of 1 should remove the vast majority of
connection related problems that appear in MaxScale. This should filter
out most of the errors caused by transient network problems.
Comparing two fixed std::strings would have equal C strings but comparing
with operator== they would be different. This was a result of the string
modification done by fix_object_name.
Converted the internal header into a C++ header, added std::string
overload and fixed use of the function.
