We ask the developer to obtain his own api credentials, because
the bundled 'api_id' / 'api_hash' are strictly limited by the server.
The old credentials still could be used for test purposes,
but the developer will need to explicitly opt-in to use them.
To be able to run on the same distributions as before we need to have
the same GLIBC version dependency as in Ubuntu 12.04, which is 2.15.
For that we need to remove all usages of GLIBC features from 2.16 and above.
Currently there are three methods used, so they're wrapped in a separate
static library, linux_glibc_wraps.
It is a separate library because it must be compiled without '-flto' flag,
otherwise the inline __asm__ is not working and we get unresolved symbols.
* Added installation command for libtool and automake: #3437

Also add some more decoders in ffmpeg configuration (wav).
Also stop audio device restart on PKEY_AudioEndpoint changes.
Also deduce channel layout from channel count in ffmpeg loaders.
Something has changed in Qt libraries remote layout so now the perl
init-repository script from the old Qt version doesn't work anymore.
We init the submodules using script from the latest Qt version and
after that we checkout the desired version by tag in all submodules.
