"f + 0.5" does not round correctly for values very close to
".5" for every integer multiple, e.g. "0.499999975".
Found by clang-tidy's "bugprone-incorrect-roundings" check.

Currently, we are mixing: #if HAVE_BLAH with #if WITH_BLAH.
Things got way better with Pavel's work on meson, but apparently,
mixing these two lead to confusing and easy to miss bugs (see
31fb929eca for instance). While we were forced to use HAVE_
prefix with autotools, we are free to chose our own prefix with
meson and since WITH_ prefix appears to be more popular let's use
it everywhere.

The idea is to offer callers an init function that they can call
independently to ensure that the global variables get
initialized.

The virHostGetBootTimeProcfs() function is defined only for Linux
and therefore it's only call should also be done if we're on
Linux.

When we want to know the boot timestamp of the host, we can call
virHostGetBootTime(). Under the hood, it uses getutxid() which is
defined by POSIX and properly check for in configure. However,
musl took a path where it declares the function but instead of
providing any useful implementation it returns NULL meaning "no
record found". If that's the case, use our second best option -
/proc/uptime and a bit of maths.
