The list now includes all the Lua 5.3 functions listed on
https://www.lua.org/manual/5.3/#index.
Also, remove the coloring of just the library name, so that
only known library functions get highlighted.

Since a "0x" by itself is invalid. Also add word boundaries, so that
e.g. "00x1" (which is invalid) does not get partial highlighting.
Also remove some redundant backslashes from the strings regex.

Functions such as "io.close" should only be highlighted when the
package name ("io") is a word by itself, otherwise code such as
"fooio.close" gets unexpected partial highlighting.

Since file-5.10 (end of 2011), libmagic identifies a C file in most
cases as "C source" instead of as "C program". Nano's magic strings
for some other files didn't match any more what file-5.32 currently
produces, either. So, they have been adjusted, new ones added, and
old ones deleted.
This fixes https://savannah.gnu.org/bugs/?52445.
