rillig | lint: tab-align message numbers in err.c
By replacing block comments with end-of-line comments, the comments take
up less space and thus no longer require to be indented by 6 spaces.
The messages and their comments are used in 3 places: the manual page
lint.7, the err-msgs.h header for debug mode, and check-msgs.lua to
verify that the comments above the message IDs correspond to the actual
messages.
No functional change.

rillig | lint: ensure that untyped grammar rules are listed
Untyped grammar rules are suspicious because they subtly affect the
order in which the grammar actions are performed. This leads to the
various bugs mentioned in msg_347.c.

rillig | lint: add initial support for C23
Required by xsrc/external/mit/MesaLib.old, brw_eu_validate.c, which
initializes a struct using empty braces: 'return (struct string){};'.

rillig | lint: add additional queries that are not enabled by default
In the last 18 months, several lint warnings have been made adjusted to
allow common usage patterns. For example, lint no longer warns about a
constant condition in the statement 'do { ... } while (false)' (message
161), as this pattern is well-known in statement-like macros, making it
unlikely that the 'false' is a mistake. Another example is casts
between unequal pointer types (message 247) for a few well-known
patterns that are unlikely to be bugs.
Occasionally, it is useful to query the code for patterns or events that
would not justify a warning. These patterns are modeled as predefined
queries that can be selected individually, in addition to and
independently of the existing warnings and errors.
New queries can be added as needed, in the same way as new warnings.
Queries that are deemed no longer used can be deactivated in the same
way as warnings that are no longer used.
As long as none of the queries is enabled, they produce a minimal
overhead of querying a single global variable. Computations that are
more expensive than a few machine instructions should be guarded by
any_query_enabled.

rillig | tests/lint: keep messages in test files in sync with actual messages
Each of the tests named msg_*.c repeats the template of the message, to
make the test somewhat self-contained when viewed in isolation.
This creates a redundancy, and keeping track of this manually is next to
impossible. I tried it and failed in 9 cases, even though it has just
been 2 months since I myself created the initial files and I knew all
the time that this redundancy exists.
Be fool-proof for the future by checking this automatically.

rillig | lint: align comments in code with actual messages
Redundancy is bad. Especially in this case, separating the format
strings from the actual arguments prevents the compiler from
cross-checking them.
