a6f82ba590 utils: improve gst_util_ceil_log2
According to the following comparison of algorithms, the value
for 0 and 1 was giving an incorrect result.

https://gist.github.com/ceyusa/6061b33ac109a68bcd222f6919968c9a

More information here:
https://github.com/rofrol/codeforces/blob/master/ceil_log2.c

Use a different algorithm which offers better result and keep the
performance.

8b0ae3ba87 clock: Fix calculation for number of bits needed to store a 64 bit value
It was using log2(n) but what actually is needed is log2(n) + 1. Also add a
fast-path that uses __builtin_clzll() on gcc/clang.

41f3fab3d4 clock: Fix unchecked overflows in linear regression code
The initial calculation for the precision shift was wrong and would allow for
overflows during the calculations which were not detected and lead to wrong
results.

Also add a test for a case where overflows where previously not detected and
caused a completely wrong result.

it could log the pad name more usefully.

c52212604e gst: clock: Clean up code to get the monotonic / realtime clock a bit
On Windows and macOS always use the proper monotonic clock, including
for gst_util_get_timestamp(), and initialize its state only once.

Also on macOS use clock_gettime() for the realtime clock, if available
instead of always falling back to GLib.

3963396716 gstutils: Add a utility to create a stream-id without a pad
We already have functions to generate a stream-id from pads but in the
end those pads are not even used in most cases. This adds functions to
generate a stream-id even before creating the source pads for the
element that is going to use it. For example a demuxer that is properly
implements the GstStream/GstStreamCollection API will not have a Pad but
already needs to generate a stream-id.

b99ecc78ca Replace gst-i18n-*.h with gi18n-lib.h
GLib guarantees libintl is always present, using proxy-libintl as
last resort. There is no need to mock gettex API any more.

This fix static build on Windows because G_INTL_STATIC_COMPILATION must
be defined before including libintl.h, and glib does it for us as part
as including glib.h.
