For CURLINFO_CONTENT_LENGTH_DOWNLOAD_T (commit 4efd0a9f).

CURLINFO_CONTENT_LENGTH_DOWNLOAD is deprecated and is ugly because it
uses floating point.

Fixes compiler warning because formatting unscoped enums is deprecated
since libfmt 9.

This fixes #1616

when libiconv CFLAGS are passed to the compiler. Tested under OpenWrt
with its CONFIG_BUILD_NLS, which adds libiconv include flags.

In libFLAC 0.3.4 (commit c9530118), the "dllimport" check has been
changed from "_MSC_VER" to "_WIN32", and now the MPD build is affected
by it.

Defining FLAC__NO_DLL disables the use of "dllimport", which allows
linking properly to the static libFLAC build.
