8ca48752fb utils: Add gst_util_fraction_compare() to compare fractions 
And use it for the fraction comparisons in gstvalue.c instead
of using comparisons by first converting the fractions to double.
Should fix bug #628174.

706f0f657b element: link_many should activate pads if needed 
gst_element_link_many does some magic and creates ghostpads
if needed, but it didn't set the newly created ghostpad to
active if needed. This patch fixes it.

18ecca6331 utils: speed up pad linking utility functions by not trying pads that will never work 
In gst_element_get_compatible_pad(), when trying to find a compatible pad on an
element for a given pad, there's no point in checking the element's sink pads
if the pad to link is a sink pad as well, or the element's source pads if the
given pad is a source pad already, since those would never be able to link
anyway. Should speed up linking using the convenience functions a little bit,
or at least reduce debug log output.

37e2fb1054 gstutils: Make gst_pad_proxy_getcaps() return empty caps if it's what the other side has 
gst_pad_proxy_getcaps() would return the pad template caps if the other side
returned empty caps or if the intersection of all the caps on the other side
was empty.

5fa9d942e3 utils: avoid extra hop in gst_element_link 
No need to call gst_element_link_pads_filtered with filter=NULL, which would
call gst_element_link_pads() in that way. Call it directly to save a call and
expensive gobject type checks.

0ed24bc50e utils: API: Add multiplication and addition functions for fractions 
gst_util_fraction_add()
gst_util_fraction_multiply()

keep the overhead as low as possible.

e4257e8d5f gstutils: API: Add fraction helper functions 
gst_util_greatest_common_divisor()
gst_util_double_to_fraction()
gst_util_fraction_to_double()

Using these instead of going over GValue has much lower overhead.

Also add float<->fraction transform functions for GValue.

fcc5d783df pad: add variants of gst_pad_get_caps() that don't copy caps. Fixes #590941 
In most places in core and baseclasses we just need the caps to do caps-
intersections. In that case ref'ed caps are enough (no need to copy).
This patch also switches the code to use the new functions.

8d1aeeb2af utils: Use gcc's __uint128_t for 64bit unsigned integer scaling 
This is available in newer gcc releases and it should only exist
on platforms that provide some native 128bit integer arithmetic
instructions.

The x86-64 assembly for this is still kept for non-gcc compilers
that don't provide __uint128_t magic.

378b1e30e7 utils: use shift instead of division 
We can use a shift for scaling the denominator instead of a divide since the
denom is always positive. This avoids having the compiler generate code for the
different rounding rules when scaling negative values.
