No need for extra call to some demuxer function for nothing but setting a
simple bool variable. Setting the sync flag really is nothing more than just
writing some value into a variable, so it's trivial to just to do that, instead
of having an unncessarily complex "universal setter" for that.

Since we're not indirectly writing via FILE anymore, this option has
become meaningless: it meant flushing out our in-process buffer to
the kernel, but we're now doing direct write() calls anyways.
xf86 still accepts the "flush" config file flag for backwards compatibility,
but it hasn't any practical meaning anymore.

Only key difference that calloc(), in contrast to rellocarray(),
is zero-initializing. The overhead is hard to measure on today's
machines, and it's safer programming practise to always allocate
zero-initialized, so one can't forget to do it explicitly.

No need to explicitly hard-code strings lengths when we can use
standard strlen(). Those code pathes are so cold that trying to
spare a few cycled for an (usually inlined) strlen() doesn't seem

The code is easier to understand, but also more robust (eg. against struct

Using calloc() instead of malloc() as preventive measure, so there
never can be any hidden bugs or leaks due uninitialized memory.
The extra cost of using this compiler intrinsic should be practically
impossible to measure - in many cases a good compiler can even deduce
if certain areas really don't need to be zero'd (because they're written
to right after allocation) and create more efficient machine code.
The code pathes in question are pretty cold anyways, so it's probably
not worth even thinking about potential extra runtime costs.

1. We've got some ancient code here that's trying to open stderr (fd 2) itself,
in case it cannot write there for strange reason. POSIX defines the three
standard streams (and associated fd's) to be available on program startup
(when main() is reached). One needs a sledgehammer for breaking a system
so much that this doesn't work anymore - even calling a program directly
from /etc/inittab does provide them.
2. The current implementation is not POSIX conformant - it should use freopen(),
and it leaks FILE structure.
3. stderr is set to buffered mode, quite the opposite of POSIX - it states
stderr shall NOT be buffered. Simple and obvious reason: not risking vital
error information getting lost.
4. Placing The logfile in /usr/adm - an ancient, pre-FHS, directory that rarely
exists on modern systems. That's even hardcoded, instead of derived from
build-time given installation pathes.
Conculusio: obsolete and broken, thus removing it.

Several pieces of the code, as well as drivers are using %X, which

In the longer run, we'll have to decide whether we actually want to
implement the upper-case directive or change all callers to lower-case.
But for now it's better to just accept %X and interpret it as lower-case,
in order to fix those error messages. Whether it's printed as upper or
lower case is more or less an aesthetic matter.
