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.

Previously, the pointer was moved to undefined memory.

Increment the "path" earlier.

This was building broken paths like "/home/foo/~/bar".  Bug found by
Maarten de Vries.

Use Path::FromUTF8() for the g_get_home_dir() return value instead of
assuming it's already FS charset.

Use only ConfigData.hxx in plugin sources to reduce header
dependencies.

Replaces GLib's GError.

Migrate all callers to use Path directly, instead of doing the
conversion in each caller.

Better error messages.

Remove the slash hack, allocate memory for the user name.

Just advance the "path" pointer.

After we've been hit by Large File Support problems several times in
the past week (which only occur on 32 bit platforms, which I don't
have), this is yet another attempt to fix the issue.

It's not used anymore, its features have been moved to fd_util.c.

No CamelCase.  Use bool instead of int.  Make both arguments
mandatory.

Try to be as portable as possible, use GLib path name functions and
macros.

strcasecmp() is locale dependent, making it a bad choice for internal
string comparisons.

socket, because there is no ioctl for non-sockets on Windows

This updates the copyright header to all be the same, which is
pretty much an update of where to mail request for a copy of the GPL
and the years of the MPD project. This also puts all committers under
'The Music Player Project' umbrella. These entries should go
individually in the AUTHORS file, for consistancy.

Now that I've found this nice function in the GLib docs, we can
finally remove our custom sleep function.  Still all those callers of
g_usleep() have to be migrated one day to use events, instead of
regular polling.

config_get_string() is easier to use than config_get_param() because
it unpacks the config_param struct.

Renamed functions, types, variables.

Removed all allocation functions, xwrite(), xread(), ARRAY_SIZE().
Those have been superseded by GLib.

This always allocates strings on the heap, but we can delete the
stripReturnChar() function now.
