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Those have been superseded by GLib.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.

Currently, both sides of the pipe are blocking, although we do not
need blocking read().  Convert it back to blocking.  Eliminate the
select() from wait_main_task().

The new WIN32 version of set_nonblocking() can only deal with sockets,
i.e. it will fail on main_notify.c.  On WIN32, we have to reimplement
main_notify.c anyway, so this is not a big deal.

Sleep() has only millisecond granularity, but good enough for now.

On WIN32, parsePath() now simply duplicates the input string.  There
is currently nothing special we can do here.  The old code was not
portable on WIN32.

Use g_get_home_dir() to get the home directory of the current user.
This will be portable to win32.

Declare variables where they are really used.

Replaced myFgets() with fgets() + g_strchomp().

We want to remove gcc.h eventually. This takes care of all the
G_GNUC_MALLOC macros.

We want to remove gcc.h eventually. This takes care of all the
G_LIKELY/G_UNLIKELY macros.

Eliminate code already provided by GLib.

Prefer GLib over utils.h.

Remove duplicated code from MPD.

string_toupper() and strDupToUpper() were not able to deal with
character sets other than US-ASCII.  Use GLib's g_utf8_casefold()
for strings.

When there are standardized headers, use these instead of the bloated
os_compat.h.

This allows us to avoid the nasty repetition in strncmp(foo,
bar, strlen(foo)).  We'll miss out on the compiler optimizing
strlen() into sizeof() - 1 for string literals for this; but we
don't use this it for performance-critical functions anyways...
