a3e455694901a887e0feef69bd63e3aa122ea44b build: Add format string linter (practicalswift)
Pull request description:
Add format string linter.
This linter checks that the number of arguments passed to each variadic format string function matches the number of format specifiers in the format string.
Example output:
```
$ test/lint/lint-format-strings.sh
src/init.cpp: Expected 2 argument(s) after format string but found 1 argument(s):
LogPrintf("We have a mismatch here: foo=%s bar=%d\n", foo)
src/init.cpp: Expected 1 argument(s) after format string but found 2 argument(s):
LogPrint(BCLog::RPC, "RPC stopped. This is a mismatch: %s\n", s1, s2)
$ echo $?
1
```
