+Subject: PATCH 1/3 faac: support faac >= 2.0 (faac_* API)
+
+faac 2.0 removed the legacy faacEnc* API and bumped the library SONAME
+to 1. Detect the new API via FAAC_VERSION_MAJOR and use it when
+available, keeping the faacEnc* path for faac 1.x.
+
+With the new API the pad templates only offer the lc profile: faac 2.0
+dropped the MAIN/SSR/LTP object types, which were never actually
+implemented by libfaac. The AudioSpecificConfig buffer is library-owned
+in the new API and must not be freed. The meson header check now accepts
+either faacEncOpen (1.x) or faac_encoder_open (2.0).

+
+faac has installed a faac.pc since 1.31. Use it when available and only
+fall back to the faac.h symbol check plus cc.find_library() for older
+releases without one. Like other plugins, skip all dependency checks
+when the plugin is disabled.
