util/log: Always send errors to logfile when daemonized

When QEMU is started with `-daemonize`, all stdio descriptors get
redirected to `/dev/null`. This basically means that anything
printed with error_report() and friends is lost.

Current logging code allows to redirect to a file with `-D` but
this requires to enable some logging item with `-d` as well to
be functional.

Relax the check on the log flags when QEMU is daemonized, so that
other users of stderr can benefit from the redirection, without the
need to enable unwanted debug logs. Previous behaviour is retained
for the non-daemonized case. The logic is unrolled as an `if` for
better readability. The qemu_log_level and log_per_thread globals
reflect the state we want to transition to at this point : use
them instead of the intermediary locals for correctness.

qemu_set_log_internal() is adapted to open a per-thread log file
when '-d tid' is passed. This is done by hijacking qemu_try_lock()
which seems simpler that refactoring the code.

util/log: do not close and reopen log files when flags are turned off

log_append makes sure that if you turn off the logging (which clears
log_flags and makes need_to_open_file false) the old log is not
overwritten. The usecase is that if you remove or move the file
QEMU will not keep writing to the old file. However, this is
not always the desited behavior, in particular having log_append==1
after changing the file name makes little sense.

When qemu_set_log_internal is called from the logfile monitor
command, filename must be non-NULL and therefore changed_name must
be true. Therefore, the only case where the file is closed and
need_to_open_file == false is indeed when log_flags becomes
zero. In this case, just flush the file and do not bother
closing it, thus faking the same append behavior as previously.

The behavioral change is that changing the logfile twice, for
example log1 -> log2 -> log1, will cause log1 to be overwritten.
This can simply be documented, since it is not a particularly
surprising behavior.

util/log: Ignore per-thread flag if global file already there

If QEMU is started with `-D qemu.log.%d` without any `-d` option,
doing `log all` in the monitor fails with:

Filename template with '%d' required for 'tid'

It is confusing since '%d' was actually passed.

This happens because QEMU caches the log file name with %d converted
to getpid() since `tid` wasn't required. This name isn't suitable
for a subsequent enablement of per-thread logs. There's little cause
to change the behavior as `-d tid` is mostly used at user-only startup.

Drop the per-thread from the requested flags in this case : `log all`
will thus enable everything except `tid` instead of failing. This is
preferable over forcing the user to enable each log item individually.

With this patch, `tid` is now truely immutable : it can only be set
or unset from the command line and never changed afterwards.

util/log: Make the per-thread flag immutable

Per-thread logging was implemented under the assumption that once
enabled, it is not possible to switch back to single file logging.
This isn't enforced though and it is possible to go through the
global file opening sequence in per-thread mode. The code isn't
ready for this and produces unexpected results as detailed below.

Start QEMU in system emulation mode with `-D ./qemu.log.%d -d tid`
and then change the log level from the monitor to something that
doesn't have tid, e.g. `log cpu_reset`. The value of log_flags
is zero and per_thread is set to false : the rest of the code
then assumes it is running in the global log case and opens a
file named `qemu.log.%d`, which is obviously not an expected
behavior.

Enforce the immutability of the flag early in qemu_set_log_internal()
so that its value is correct for all subsequent users.

util/log: Close per-thread log file on thread termination

When `-D ${logfile} -d tid` is passed, qemu_log_trylock() creates
a dedicated log file for the current thread and opens it. The
corresponding file descriptor is cached in a __thread variable.
Nothing is done to close the corresponding file descriptor when the
thread terminates though and the file descriptor is leaked.

The issue was found during code inspection and reproduced manually.

Fix that with an atexit notifier.
