equalizer: Optimize calculations of alpha, beta, and gamma constants
It is easy to see that the computation of the alpha constant is slightly
inefficient, as the root value can be close to 1 for the lower frequencies,
which would result in significant roundoff error if this value is subtracted
from 1. In this patch, the computation of the alpha, beta, and gamma constants
has been simplified and refactored.

skins2: provide more info to help skin developpers debug their skins
Many skins are buggy because the bitmap sizes or the resize policy
are inconsistent with button or checkbox constraints (fixed size)
This patch will help skin developers pinpoint which button or
checkbox is at fault. In addition, the resize policy will be
corrected (guessed from the lefttop parameter). This will enable
buggy and often unmaintained skins to work fine nevertheless.
Be more stringent on what it means to be tightly-coupled for two layouts.
Note that directly resizing a playout should not be allowed. Only the skins2
windows manager should be authorized to do it, since other issues are at stake
(anchors, min/max constraints, ....). Yet, this new isTightlyCoupledWith() now
ensures that two layouts are truly identical from the windows manager's
perspective, and thus avoids possible and undesirable side effects.

contrib: gmp: Patch away the ansi2knr mentionings
The latest automake versions (as built by extras/tools) have
removed support for ansi2knr altogether, so this is required for
reconfiguration to work. We still need to do the reconf since the
host system ANSI check in the tarball is broken.

contrib: Set _CMAKE_TOOLCHAIN_PREFIX
This is required for detecting ar and ranlib properly, required
e.g. when cross compiling for android from OS X.
One can't set CMAKE_AR or CMAKE_RANLIB directly. Normally they
should be set properly automatically within cmake, but those
codepaths seem to be skipped when we set the C/CXX compilers
manually.
skins2: fix video not properly tied to the right video control
Certain skins like wmp12 may fail to deal with video controls in some
corner cases. For this skin, no window was set visible and the skin
engine eventually fell back to force the first window to become visible.
This patch is expected to fix trac #8368 (need to be tested on windows)

contrib: Fix a bug in the old gmp configure script
The brackets in the config test aren't properly escaped, and thus
don't end up in the final configure script as intended.
When building on a system where the system default compiler is clang,
clang can fail due to the main signature
"int main(int argc, char *argv)" being invalid,
which makes configure believe that the system compiler isn't
ANSI compliant, and it tries to invoke (broken) ANSI2KNR code.

opengl: Allow using the RGBA shader for the main picture
So far, the RGBA shader has only been used for the subpictures.
On ES2, the fixed function pipeline is not available, so we need to
use the shader for drawing the main picture even if it is RGBA.

avcodec: cleanup encodeAudio
Handle better cases when we don't have input frame size
same as encoder input frame size. Also gather input samples
untill we get full frame fillet and not just next block.
Set length based on used samples and not frame_size
Also try to make memory calculations cleaner so they don't
overshoot and write stuff all over.
Forcefully resizing only makes sense when layouts were designed to be similar
in size in the first place. Furthermore, it cuts off a larger layout if a
smaller one is first defined when loading a skin.
Ideally, the skins2 dtd should be extended for skins developers to explicitly
express whether two layouts are tightly-coupled or not, i.e should always be
kept the same size whatever the subsequent resizing performed by the user.

skins2: add a function that differentiates dependent and independent layouts.
In skins2, a window can have multiple layouts with two different goals.
First goal, layouts have the same original size and only differ in the
presentation (different color, ...). If the active layout gets resized,
the user expects the related inactive layouts with the same size to
automatically resize, should they become active.
Second goal, layouts are different in size, e.g a reduced layout and an
expanded layout. In this case, resizing the active layout doesn't mean
resizing the other inactive layouts, since they were not meant to be
similar in size in the first place.
This patch creates a function that will be used to differentiate these
two different use of layouts.

skins2: improve $N text variable
Instead of hardcoding what we think the name of the current item is, make it
configurable via the --input-title-format parameter.
This change makes skins2 more consistent with qt4 that already uses this
means to set the title of the main window.
Default display will now be "artist + title" instead of just "title".
Users who would still prefer the previous behaviour can get it with
--input-title-format '$t'

Add hotkeys to cycle through previous/next program SIDs.
Change "cycle through program SIDs" to support cycle both ways (prev/next).
With this commit, it is possible e.g. to quickly change between neighbor

Default size was wrong.
Text was really hard to real in that tiny box: lots of line breaks and
