build: raise an error if pkg is not found Changed FFmpeg, PCSC and PulseAudio cmake find to raise an error if an required package was not found.

# - Try to find FFmpeg
# Using Pkg-config if available for path
#
# FFMPEG_FOUND - all required ffmpeg components found on system
# FFMPEG_INCLUDE_DIRS - combined include directories
# FFMPEG_LIBRARIES - combined libraries to link
build: check libavcodec api version If pkg-config is available libavcodec api version is checked and cmake fails if the required version isn't available. In case pkg-config isn't available a notification message with the required version is printed. This fixes/prevents #740.

[cmake] Locate PkgConfig module with find_package() instead of include(FindPkgConfig) This is the contemporary way of including find modules and including the find module this way avoids cmake errors in conjunction with find_package_handle_standard_args().

Rewrite of sound and microphone channels The sound and microphone redirection channels (and in part TSMF) did not properly decouple encoding/decoding from the backends used to play/record sound.

pkg_check_modules(AVRESAMPLE libavresample)
Move from libavresample to libswresample - The libavresample as part of FFmpeg was declared as deprecated in favor of libswresample on Dec 25 2017 in commit "lavr: deprecate the entire library" (https://github.com/FFmpeg/FFmpeg/commit/c29038f3041a4080342b2e333c1967d136749c0f ; https://git.ffmpeg.org/gitweb/ffmpeg.git/commitdiff/c29038f3041a4080342b2e333c1967d136749c0f). As major Linux distributions (RPM, DEB and Archlinux) provide now FFmpeg and libswresample as its part use the libswresample instead of libavresample.
