gnutls: Revert license to LGPLv2Plus

Since version 3.1.10, gnutls has reverted to the lgpl v2. So
let's mention that.
libnice: Disable gtk-doc unconditionally, and disable static by default

gtk-doc support needs the .pc file, which isn't inside Cerbero and causes
a build failure.

Static plugin libraries should only be installed by the -static recipe.
libnice.a is still needed inside libnice.recipe, though.

recipes: Fix dependencies for librsvg

Conflicts:

Compile schemes for gsettings
Remove all references to GNonLin, it has been replaced by NLE

Currently directly in GES, and in the future should land in -base
commands:package: Do not build devel only package when --no-devel

Making sure static variants will not be built when packaging with
--no-devel
packages:pitivi: Do not build unnecessary dependencies
cerbero: Add support for Ubuntu Utopic (14.10)
bootstrap: On redhat it's fuse-devel, for real now

openssl: Fix libdir, install libtool file, etc

* libdir is /lib even on linux_x86-64, not /lib64 as the build system guesses.
* Install a libtool file, as needed by Cerbero.
* Remove useless RAND_bytes redefinition. This problem was fixed in libnice.

libsrtp: Install a libtool file as well

cerbero/utils/git: Use 'cerbero_build' as the branch for applying patches

'build' is too generic, it's a good idea to use a namespaced branch name

libsrtp: Fix build on Windows, and fix library name on OS X
