Also had to fix a few of the audacious files to get them to compile, mainly not using NULL in the input plugin constructor and casting the STREAMFILE functions (maybe some *nix compilers would've accepted those, but FreeBSD 12's Clang did not)
It was implemented for Audacious only to open companion NWA files, but
current version has no need for it. In case there is some obscure thing
that needs it, Audacious's vfs.cc should translate or return realnames
transparently, without having to modify other streamfiles.
Makefile.audacious.am:
* Add test/ subdirectory to the Autotools build
* Add version.h to EXTRA_DIST so that "make distcheck" passes
audacious/Makefile.audacious.am:
* Install Audacious plug-in into the appropriate directory
* No need to include CXXFLAGS in AM_CXXFLAGS, as the former is already
included in the compiler invocation
configure.ac:
* Need to link to libvorbis in order for static-library builds
(--disable-shared) to link correctly
* Only add GCC-specific compiler flags if GCC is detected
* Tightened up the GCC warning flags
* Don't set LIBS, so that different targets can link against different
libraries
* Generate makefile for test/ subdirectory
src/Makefile.audacious.am:
* Install libvgmstream into the library directory
* Removed GCC-specific flag from AM_CFLAGS
* No need to include CFLAGS in AM_CFLAGS, as the former is already
included in the compiler invocation
* Add libvgmstream dependencies via LIBADD instead of global LIBS var
test/Makefile.audacious.am:
* New makefile template for test/ subdirectory
unbootstrap:
* Also remove "compile" script from bootstrap
Handle new VFSFile throwing an error correctly, which requires checking the m_impl status of VFSFile. Conveniently, there's a bool operator on the class exactly for that purpose.
