Mike Brady 54d761ff7d Clean up some of the wording and layout of the configuration file
Clean up and improve the way lead-in sillence is used to give a more accurate sync time to the first packet of audio.
Allow very good sync to occur with 0.3 seconds of lead-in silence.
Improve the use of the buffer offset.
Format some other files.

Mike Brady 02224666da Squashed commit of the following:
Don't use strndup as old versions of OpenWrt don't seem to have it
    Update FREEBSD.md
    Fix comparison between old and new metadata strings by checking they have equal lengths as well.
    Remove a redundant definition to prevent use on an uninitialised copy, clean up some of the less-used backends
    Remove some unwanted and unused variable declarations from audio_dummy.c and audio_soundio.c
    Add the -fno-common flag to compilation.
    Treat the "mper" attribute as the 64-bit item that it is rather than a 32-bit item as hithereto. Output it as a hexadecimal number to correspond with the format of the track id obtained from AppleScript
    Make changes to that it compiles under gcc-10 with -fno-common
    Add a SIGCHLD handler to reap zombie processes generated after script invocations where wait_for_completion is set to "no".
    Update and rename CONTRIBUTING.md to REPORTING ISSUES.md
    Add a few more commands and clarify some text.
    Change from talking about a server to talking about a client. Technically, e.g. iTunes is a client of Shairport Sync.
    Store the UserAgent so as to recognise forked-daapd so as to always send a revision_number of 1 when asking for playerstatus of forked-daapd.
    Add or update some of the copyright notices
    Add the ability to set the volume directly to the D-Bus RemoteControl interface and to the MPRIS interface. Both use the recently-discovered ability to set the device_volume.
    Merge in Pieter De Gendt's work on resampling on the jack backend.
    Merge pull request #939 from pdgendt/feature/jack-soxr-resampling
    Add SetAirplayVolume to the D-Bus RemoteControl interface.
    Add SetVolume to the MPRIS interface.
    Hook up the Volume property in the MPRIS interface.
    Modify RemoteCommand in the D-Bus interface to return the HTTP status and response.
    Change the type of airplay_volume from int to double in the metadata hub.
    Add a few sample commands in the D-Bus document.

Update sample D-Bus commands
Add D-Bus convolution filter controls -- enable convolution filters to be turned on and off or changed; enable convolution gain to be checked and changed; fix loudness control.
Fix D-Bus loudness switch silencing output. Rename LoudnessFiulterActive to Loudness. Add Convolution, ConvolutionGain and ConvolutionImpulseResponseFile properties to the D-Bus interface.

Chris Boot b9cf91b2bb More typo fixes across the tree
Previously I have made spelling changes as caught by Debian's lintian
tool, which has a short list of common misspellings that it tests for.
This time I decided to run codespell against the source and fix all the
obvious problems it came up with. It also uses a list of misspellings
but it's much larger than lintian's, but also has some false positives
so I went over the list by hand.

The command I used to do check the source was:
git ls-tree -rz --name-only HEAD | xargs -0 codespell -L minimise,errorstring

Mike Brady a8faacd3fc Expose some of the settings used in the disable_standby_mode.
Specifically, firstly, the disable_standby_mode_silence_threshold, which is the
amount of audio in the output device's hardware buffer. It should normally
be close to the value givein in the audio_backend_buffer_desired_length_in_seconds
setting. If it drops to this value, silence is added to the buffer to prevent
the output device from becoming idle.

Secondly, the disable_standby_mode_silence_scan_interval is the time between checks
of the output device's hardware buffer.

The code for generating frames of possibly-dithered silence has been simplified.
