util.format: Handle Lua 5.5 change in precision tostring(big number)

sed -i '/73786976294838206464/s/equal("\[7\.3786976294838e+19]"/matches("%[7%.3786976294838%d*e%+19%]"/'
sed -i '/73786976294838206464/s/equal("7\.3786976294838e+19"/matches("7%.3786976294838%d*e%+19"/'

Don't think this change in Lua affects anything else, we shouldn't be
depending on the exact number format tostring() uses.

Part of #1600

util.format: Skip control code escaping when doing full serialization

util.format: Skip control code escaping when doing full serialization

Fixes that a multi-line string ended up "like\
\9this" instead of "like\nthis" as can be demonstrated by somehow
initiating a connection to a HTTP server.

util.format: Fix some formats expecting positive numbers in Lua 5.2

Amazing how string.format behaves differently under each Lua version

util.format: ALL THE TESTS!!!

util.format: ALL THE TESTS!!!

The more tests I made, the more Lua 5.1 quirks I discovered.

Tests generated using a tool plus some touch-up.

util.format: Also handle the %p format added in Lua 5.4

util.format: Ensure sanitation of strings passed to wrong format

util.format: Ensure sanitation of strings passed to wrong format

Ie. log("debug", "%d", "\1\2\3") should not result in garbage.

Also optimizing for the common case of ASCII string passed to %s and
early returns everywhere.

Returning nil from a gsub callback keeps the original substring.

util.format: Escape invalid UTF-8 by passing trough serialization

util.format: Escape invalid UTF-8 by passing trough serialization

Should prevent invalid UTF-8 from making it into the logs, which can
cause trouble with terminals or log viewers or other tools, such as when
grep determines that log files are binary.

util.format: Change formatting of nil values to avoid looking like XML

util.format: Escape ASCII control characters in output

util.format: Escape ASCII control characters in output

This should offer some protection against doing evil things to
terminals. Doesn't protect against pure broken UTF-8 garbage however.

See #734

Improves eg debug logs

Because [] seems exsessive
