This delays label_init(), and drops the (duplicate) printing of version
information.

Also move the rest of event initialization next to the event loop (no functional change).

Rather than printing debug output to stderr and redirecting this to /dev/null when not wanted,
use the correct log_*() function in the first place.

Once upon a time logging during early boot was unreliable, so extra logging messages were
sent by udev to stderr. That is no longer a concern, so drop all fprintf() calls from udved.

It is redundant to store 'hash' and 'compare' function pointers in
struct Hashmap separately. The functions always comprise a pair.
Store a single pointer to struct hash_ops instead.
systemd keeps hundreds of hashmaps, so this saves a little bit of
memory.

Branch v2.X breaks from v1.X in that it removes the userland
firmware loading support.

This extends the udev parser to support OP_REMOVE (-=) and adds support
for TAG-= to remove previously set tags. We don't fail if the tag didn't
exist.
This is pretty handy if we ship default rules for seat-assignments and
users want to exclude specific devices from that. They can easily add
rules that drop any automatically added "seat" tags again.

This commit follows upstream's
4c83d994566718043e61e568cc214bdc4587f869
We adopt their removal of excessive logging, but we do not switch
to one rtnl per worker, rather than per event. This maintains
code separation between libsystemd and udev code. The disadvantage
is that we do not get the cost savings of having one rtnl per
worker rather than per event.

Some kernel modules still take more than one minute to insmod, we no longer rely on the timeout
killing insmod within a given period of time, so just bump this to a much higher value. Its only
purpose is to make sure that nothing stays aronud forever.

The only remaining user was 'starting version XXX', which is now logged using log_info().
Basile: There were also print_kmsg in udev-event.c which I switched to log_info().

If you stack container_of() macros, you will get warnings due to shadowing
variables of the parent context. To avoid this, use unique names for
variables.
Two new helpers are added:
UNIQ: This evaluates to a truly unique value never returned by any
evaluation of this macro. It's a shortcut for __COUNTER__.
UNIQ_T: Takes two arguments and concatenates them. It is a shortcut for
CONCATENATE, but meant to defined typed local variables.
As you usually want to use variables that you just defined, you need to
reference the same unique value at least two times. However, UNIQ returns
a new value on each evaluation, therefore, you have to pass the unique
values into the macro like this:
#define my_macro(a, b) __max_macro(UNIQ, UNIQ, (a), (b))
#define __my_macro(uniqa, uniqb, a, b) ({
typeof(a) UNIQ_T(A, uniqa) = (a);
typeof(b) UNIQ_T(B, uniqb) = (b);
MY_UNSAFE_MACRO(UNIQ_T(A, uniqa), UNIQ_T(B, uniqb));
})
This way, MY_UNSAFE_MACRO() can safely evaluate it's arguments multiple
times as they are local variables. But you can also stack invocations to
the macro my_macro() without clashing names.
This is the same as if you did:
#define my_macro(a, b) __max_macro(__COUNTER__, __COUNTER__, (a), (b))
#define __my_macro(prefixa, prefixb, a, b) ({
typeof(a) CONCATENATE(A, prefixa) = (a);
typeof(b) CONCATENATE(B, prefixb) = (b);
MY_UNSAFE_MACRO(CONCATENATE(A, prefixa), CONCATENATE(B, prefixb));
})
...but in my opinion, the first macro is easier to write and read.
This patch starts by converting container_of() to use this new helper.
Other macros may follow (like MIN, MAX, CLAMP, ...).

fprintf() does not add new-lines automatically like log_*() does. Add the
missing \n specified so "udevadm" invoked without arguments adds a newline
to:
udevadm: missing or unknown command

This way we can use it on non-const strings, and don't end up with a
const'ified result.
This is similar to libc's strstr() which also takes a const string but
returns a non-const one.
