Previously, calling _int_free from _int_memalign could put remainders

low-level allocator.  This results in missed merge opportunities
because once these freed chunks become available to the low-level
allocator, further memalign allocations (even of the same size are)
likely obstructing merges.

Furthermore, during forwards merging in _int_memalign, do not
completely give up when the remainder is too small to serve as a
chunk on its own.  We can still give it back if it can be merged
with the following unused chunk.  This makes it more likely that
memalign calls in a loop achieve a compact memory layout,
independently of initial heap layout.

Drop some useless (unsigned long) casts along the way, and tweak

linux: statvfs: allocate spare for f_type

This is the only missing part in struct statvfs.
The LSB calls [f]statfs() deprecated, and its weird types are definitely
off-putting. However, its use is required to get f_type.

Instead, allocate one of the six spares to f_type,
copied directly from struct statfs.
This then becomes a small glibc extension to the standard interface
on Linux and the Hurd, instead of two different interfaces, one of which
is quite odd due to being an ABI type, and there no longer is any reason
to use statfs().

The underlying kernel type is a mess, but all architectures agree on u32
(or more) for the ABI, and all filesystem magicks are 32-bit integers.
We don't lose any generality by using u32, and by doing so we both make
the API consistent with the Hurd, and allow C++
  switch(f_type) { case RAMFS_MAGIC: ...; }

Also fix tst-statvfs so that it actually fails;
as it stood, all it did was return 0 always.
Test statfs()' and statvfs()' f_types are the same.

test was enhanced and the object for __builtin_return_address (0)

as the highest bit has to be masked out.  This can be done with
__builtin_extract_return_addr.

content of dlfo is invalid, which may lead to segfaults in basename.
