If __x is signed and its value is the minimum allowed for the type,
(__x - 1) causes a signed overflow, which has an undefined
behavior. Compiling with -fsanitize=undefined produces the warnings:
test-general.c:4499:619: runtime error: signed integer overflow: -2147483648 - 1 cannot be represented in type 'int'
test-general.c:4506:681: runtime error: signed integer overflow: -2147483648 - 1 cannot be represented in type 'TEST_IS_POWER_OF_TWP_ENUM_SIGNED'
test-general.c:4501:619: runtime error: signed integer overflow: -9223372036854775808 - 1 cannot be represented in type 'long int'
test-general.c:4509:691: runtime error: signed integer overflow: -9223372036854775808 - 1 cannot be represented in type 'TEST_IS_POWER_OF_TWP_ENUM_UNSIGNED_64'
Change the order of expressions to avoid this.

It is valid to call nm_clear_g_signal_handler() with missing
@self argument if (and only if) the @id is unspecified as well.
Remove the check for @self to get an assertion in case @id
is missing *and* @self is invalid. In this case,
g_signal_handler_disconnect() will raise a g_critical() for us.

It does not make sense to issue an error. This should be a helper function.
"NetworkManager[18341]: nm_clear_g_signal_handler: assertion 'G_IS_OBJECT (self)' failed"
error started since commit e6d7fee5a6 due to that.

All current users of NM_IN_SET() would rather use short-circuit evalation
(or don't care). It seems that doing it by default seems favorable.
The only downside is, that this might have somewhat unexpected behavior
to a user who expects a regular function (which would evaluate always
all arguments).

Let the preprocessor do more work, but generate a simple expression that
the compiler can optimize (presumably) better.

We already have "nm-utils*.h" and "NetworkManagerUtils.h" headers. Rename
"include/nm-utils-internal.h" to "nm-macros-internal.h". I think that
name is better, because this file is header-only, internal, and
repository-wide.
Also, it will never contain non-header-only declarations because
there is no backing object file under "include/".
It will only contain macros and inline functions.
