Both callers pass non-nullptr.

Lifts the artificial 31 bit limit in i386 where
sizeof(long)==sizeof(int).

The "loop_count" configuration parameter allows the user to set how
many times a module with backward loops shall loop. "0" (the default)
means a module is not allowed to use backward loops at all. "-1"
enables inifinite looping.

Now config_param::GetBlockValue() can be used to get signed integers
from the configuration.

Fixes a regression from 752dfb3d which
caused the current chunk to be flushed as soon as new replaygain
information was found. If this occurs on a tag chunk, it has no data
(length 0) and is then skipped before pushing it to all of the outputs.

This change allows 0-length chunks through if they contain a tag and
they are now appearing in mplayer and mpv properly.

This patch allows the user to configure the mikmod decoder plugin to loop
modules. It adds a configuration parameter to the mikmod decoder called
"loop" which can be "no" (the old behaviour, default) or "yes" to allow
modules to use backward loops.

Worst-case allocation using MAX_CHANNELS.

Overload the name.

Finally fixes the regression by commit c1f4f1fd.

Eliminate the global variable "shutdown_loop".

Fix for a major memory leak.

The new class Path only holds a string pointer without being
responsible for allocation/deallocation.  The FileSystem.hxx library
accepts Path arguments instead of AllocatedPath, to avoid forcing
callers to allocate another string object.

If fs_charset is empty, i.e. we're using the default "utf-8",
GetFSCharset() should return exactly that instead of an empty
std::string.

Implement a fast path for UTF-8 which leaves fs_charset empty, and
don't assign a value to fs_charset if there's no configuration.
