lint: warn about function definitions without header declaration

The existing warning was only issued for function declarations, not for
function definitions.

The interesting change in the tests is in msg_351.c.  Many other tests
use non-static functions due to their syntactic brevity.  In these
tests, the warning is disabled individually, to allow new functions to
be added without generating warning 351.

tests/lint: extend tests for sizeof and alignof

lint: make alignof(incomplete enum) an error

tests/lint: add more tests for sizeof, offsetof, alignof

lint: add quotes around placeholders for the remaining messages

Reword some of the messages slightly, exchanging brevity for clarity.

Message 138 is kept as-is, as it is not yet covered by any tests.

Message 240 is kep as-is, as it is unreachable.

lint: merge duplicate grammar rules for __alignof__ expr

This allows expressions like '__alignof__(ptr)->member', just as with
'sizeof'.

The upper rule in the grammar was preferred over the lower rule since it
shifted the T_LPAREN instead of reducing unary_expression.  Its
implementation invoked undefined behavior if the expression was NULL
since it didn't assign anything to $$.

tests/lint: add more tests for __alignof__

lint: add support for __alignof__ expr, a GCC extension

Seen in lib/libc/gmon/gmon.c:153.

lint: fix support for __alignof__, add support for __alignof

Broken since lex.c 1.129 from yesterday.

tests/lint: adjust tests to reflect missing support of __alignof__

The change in lex.c 1.129 attempted to add support for __alignof, in
addition to the existing support for __alignof__.  It failed by removing
support for __alignof__, while allowing the plain 'alignof' instead.

lint: add common header for all tests

For those tests that didn't use GCC-style line markers such as "# 2",
the line numbers of the diagnostics stay the same.  This is purely
conincidental.  Before, the 3 lines came from lint's built-in
definitions (see 'builtins' in main1.c), and line number counting
continued as if nothing had happened, making the first line of the
actual file line 4.  These 3 built-in lines are now replaced with 3
lines of file header.
