The former was deprecated with C++14.

Since we switched from autotools to Meson in commit
94592c14, we don't need to include
`config.h` early to properly enable large file support.  Meson passes
the required macros on the compiler command line instead of defining
them in `config.h`.

This means we can include `config.h` at any time, whenever we want to
check its macros, and there are no ordering constraints.

Obsolete class CloseSongEnumerator, which was a kludge.

Fixes truncated lines in m3u and cue files (regression by commit
67958f7f).

Let the caller decide whether to strip.  Only remove \n and \r
(end-of-line markers).

Look at the buffer first, before trying to read from the file.  This
reduces overhead because we don't refill the buffer after every line.

Revert to the old API before commit e9e55b08, removing unnecessary
bloat.

Prepare to migrate away from GLib.  Currently, we're still using GLib
as a backend.

Replaces GLib's GError.

Fixes endless loop when the last line of a text file was not
terminated (bug 3470).
