3c09381cef utils: defer getting the classes until we actualy need them
This function has a lot of early returns. Give them soem more benefit.

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.

c6f2a94777 utils: fix proxy_getcaps
Make it return the padtemplate caps on errors and no parent.
Only intersect pads of the oposite direction of the source pad.

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

These work on plain integers instead of GValues to
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.

f63ecd04a8 pad: rename new api from _refed to _reffed.
Due to popular demand rename the new api as we still can.

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.
API: gst_pad_get_caps_refed(), gst_pad_peer_get_caps_refed()

82526701f0 pad: don't intersect with any in proxy_pad_get_caps
We initialize the caps with any and if a pad has NULL caps, just skip it instead
of intersecting with any. Also add branch prediction here.

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.

d8911f269f utils: optimize for x86_64 with some inline asm
64bit x86 has native 64x64->128 bit multiply that we can use with some inline
assembler to speed up large multiplications.
Use bsr to find the number of leading zeros more efficiently.

gst_util_uint64_scale_int_round()

gst_util_uint64_scale_round()

db6f445620 Revert "element: Set the originating pad as message source in gst_element_found_tags_for_pad ()"
This reverts commit bebfde7502.

This change shouldn't be done in a stable release series as
applications are actually expecting the sender to be an
GstElement. One example is totem.

8af9d58ea7 gstpad: fix gst_pad_can_link()
Move the gst_pad_can_link() implementation from gstutils to gstpad and use
gst_pad_link_prepare() to make it work correctly and also check the caps.

Make the broken implementation in gstutils static.

Small cleanups in the _get_fixed_caps() function.

3c6448c64e API: Add gst_util_array_binary_search() for binary searchs on a sorted array
This will be mostly useful in all elements that have some kind of internal
seek/index table. Currently almost all of them (or even all of them)
are using a linear search although the used array is already sorted,
wasting some CPU time without good reason.

Fixes bug #573623.

Original commit message from CVS:
* gst/gstutils.c: (gst_element_get_compatible_pad):
Check if the caps of the pads are compatible before returning
a pad and claiming it is compatible. This, among other things,
fixes a bug with gst-launch where an incompatible pad is chosen
and linking fails. Fixes bug #544003.
