* glib/gslice.[hc]: added mem_error() and mem_assert() to test and
handle errors without depending on gmessage.c which might not be
setup when the error occours.
removed G_SLICE_CONFIG_ALWAYS_FREE config option, fixed the code so
always freeing can be achieved by adjusting the working set time to
0 with G_SLICE_CONFIG_WORKING_SET_MSECS.
added G_SLICE_CONFIG_COLOR_INCREMENT to test different color increments
(mainly 0 and 1). reduced the minimum block size to 128 bytes, to
minimize wastage if small amounts of differently sized structrues are
allocated, this does come at a performance cost of roughly 5% though.
fixed up block alignment calculation, so it works for varying
block sizes. only use strerror() not g_strerror() since the latter
depends on working GQuark and GSlice.
mem_error(): implemented in terms of fprintf and vfprintf.
* tests/slice-color.c: new program to test cache colorization effects.
* tests/slice-test.c: trade G_SLICE_CONFIG_ALWAYS_FREE for 0 duration
G_SLICE_CONFIG_WORKING_SET_MSECS.

* glib/gslice.c: implement chain walking for arbitrary ->next pointer
offsets in g_slice_free_chain_with_offset() based on a patch by behdad
in bug 323178. moved time consuming logic from g_slice_free() out of
the inner loop, so g_slice_free_chain_with_offset() provides a real
performance benefit over g_slice_free1() now.
* glib/gslice.h: renamed g_slice_free_chain() to
g_slice_free_chain_with_offset(). implemented g_slice_free_chain() as
a type-safe macro as suggested in bug 323178.
simplified the macro implementation of g_slice_free() and implemented
it in a type safe manner for all compliers as suggested by Morten
Welinder <mortenw@gnome.org>.
* glib/gmain.c:
* glib/glist.c:
* glib/gslist.c:
* glib/glib.symbols: s/g_slice_free_chain/g_slice_free_chain_with_offset/

* glib/gslice.c: improved gettimeofday() timer resolution by maintaining
acceptable load distribution of the syscall.
(slab_allocator_free_chunk): reduce minimum/single-thread magazine sizes
to approximately page_size/2.5 to avoid excessive startup allocations.

* glib/gslice.[hc]: new slice allocator implementation.
* tests/slice-test.c: added random slice allocation test.
* glib/gthread.[hc]: removed newly added private thread mem API.
* glib/gthreadinit.h:
* glib/gmessages.c:
* glib/gthread.c:
* glib/gmem.c: divided glib threading initialisation into three phases,
initialisation where private keys and messaging are not available (only
needed by gmem.c), initialisation without messaging but private keys
available (gslice.c, gmessage.c), and full fledged initialisers that
server the rest of glib. initialisation functions got renamed to reflect
the limitations of their corresponding phases.
* glib/gmem.c: removed memchunk code, defer allocations to
g_slice_* instead.
* glib/gmem.[hc]: removed g_slice_* skeletons.
* glib/glib.symbols: added g_slice_* symbols.
* configure.in: check for availability of posix_memalign(3), memalign(3)
and valloc(3).
* glib/Makefile.am: added gslice.[hc].
