uncrustify nl_split_if_one_liner setting

... using uncrustify mod_paren_on_return config

White-space changes only, exception being the rare insertion of NL before
closing brace (couldn't find the option to disable that behavior).

I excluded some header files (e.g. sbbs.h) since uncrustify seemed to be doing
more harm than good there. I might just end up applying different set of rules
to .h files.

Should calm the clang warnings reported by Deuce:

e.g.
passing 'char *[18]' to parameter of type 'const char **' discards qualifiers in nested pointer types

Mainly capitalization, but some typos and added details. 

This macro has expanded to nothing for a while now and even before, the usage was misguided and unnecessary as explained in this video: https://www.youtube.com/watch?v=cjotPqQxxAY

Also, fix things that incorrectly reach into the protected_*_t to
incorrectly access values.

I'm fed-up with MSVC assertions in ctype functions (e.g. isdigit, isprint, isspace, etc.) when called with out-of-range (e.g. negative) values.

This problem only affects MSVC debug builds, but if you run them (like I do), these things are like little time bombs that can drive you crazy (knocking your board out of service).

The new macros names are bit more descriptive as well.

HANDLE_PENDING() contains a return, so it's theoretically possible that the
memory allocated by the previous JSVALUE/STRING_TO_... allocation could
be leaked. So now we pass an optional pointer to HANDLE_PENDING() which will
call free() on it if it's not NULL, and then sets it to NULL for good measure.

obsolete.  If there is no IPv4 address, return "255.255.255.255".

Rename the array to interface_ip_addr_list.

Some work still needs to be done on js_msgbase.c,  js_user.c, and mailsrvr.c

Only js_ValueToStringBytes() still leaks.
