Rewrite most of GHashTable to use open addressing with quadratic
probing instead of chaining. This has the potential to reduce memory
fragmentation significantly, while being slightly faster due to
better locality and no need to call alloc/free functions for nodes.
Benchmarks suggest it also uses less memory overall.
* glib/ghash.c (prime_mod): Table of suitable primes for
initial-probe distribution.
(g_hash_table_set_shift): New function.
(g_hash_table_find_closest_shift): New function.
(g_hash_table_set_shift_from_size): New function.
(g_hash_table_lookup_node_for_insertion): New function.
(g_hash_table_lookup_node): Rewritten to return node index instead of
pointer, use quadratic probe on flat table, and not return insertion
data. The latter saves some computation for read-only lookups.
(g_hash_table_remove_node): Rewrite to take a pointer directly to the
node structure to remove, and clear that. Remove unlinking code.
(g_hash_table_remove_all_nodes): Rewrite to not clear nodes
individually, but en masse using memset () after potentially calling
notify functions.
(iter_remove_or_steal): Use new data structure and algorithm. Vastly
simplified - now just a call to g_hash_table_remove_node ().
(g_hash_table_resize): New resize code, re-indexing with new prime
and cleaning up tombstones.
(g_hash_table_maybe_resize): Table may hold 8 buckets minimum, no less
than 1/4 load excluding tombstones, and no more than 15/16 load
including tombstones. These numbers are the results of a lot of
benchmarking with multiple complex applications, and should not be
changed lightly.
(g_hash_table_iter_next)
(g_hash_table_lookup)
(g_hash_table_lookup_extended)
(g_hash_table_insert_internal)
(g_hash_table_remove_internal)
(g_hash_table_foreach_remove_or_steal)
(g_hash_table_foreach)
(g_hash_table_find)
(g_hash_table_get_keys)
(g_hash_table_get_values): Use new data structure and algorithm,
fairly trivial changes.

* glib/gutils.c (_glib_get_dll_directory)
* glib/gspawn-win32.c (do_spawn_with_pipes): Be a bit less
restrictive, look for the helper programs in the same folder where
the GLib DLL is, not necessarily in a "bin" subfolder of the top
GLib installation folder.

* gcontenttype.c (g_content_type_guess): can't assign the return
value of g_strdupv() to an array. Fill the array manually with
const strings instead (it is never freed anyway). Fixes the
build. Also fixed indentation.

* gdesktopappinfo.c (g_desktop_app_info_new_from_keyfile):
Fix trivial typo to unbreak the build (there was a colon
instead of a semicolon at the end of a statement).

* win32/vs9: New folder. Project files for use with MSVS9. Based
on the MSVS8 project files is win32/vs8. Four configurations:
Debug|Win32, Release|Win32, Debug|x64 and Release|x64. DLL names
simplified to of the style glib-2-vs9.dll.

* glib/gtimer.c (g_time_val_to_iso8601): time_t is 64 bits in all
the newer Microsoft C libraries, not just 64-bit ones. So to avoid
crash if compiled with newer MSVSes, use a separate time_t
variable in all cases on Windows.

* glib/gbacktrace.h: Define G_BREAKPOINT() also for 64-bit MSVC,
using the __debugbreak() intrinsic.

* gcontenttype.c (g_content_type_guess): Check whether there's a '/'
at the end of the filename, and declare it a directory.

* win32/vs8/*.vcproj: Drop the "win32" part from under
"dependencies" so that the same project files can be used also
for 64-bit compilation by just having a different
"dependencies" folder containing 64-bit packages instead. At
least, I hope it will work out some way like that. MSVS
project files really are a pain to maintain. Much information
is typically copied for four different configurations
"Debug|Win32", "Release|Win32", "Debug|x64" and "Release|x64"
instead of having common stuff listed just once and only different
parametrisations. Or am I missing something?
Make the "Release" configuration work, too. Use correct character
set for the gspawn-win32-helper programs. Use correct subsystem
for the non-console one.

* win32/vs8/*.vcproj: Don't use Detect64BitPortabilityProblems
as those warnings are misleading. They don't take into
consideration ifdefs in glibconfig.h and elsewhere for _WIN64.

* win32/vs8/*.vcproj: Update to match the Makefile.am files. Drop
G*_EXPORTS from PreprocessorDefinitions, nothing looks for such
macros. Add G_DISABLE_DEPRECATED. Add PCRE_STATIC for glib to
avoid exporting the pcre functions. Add G_LOG_DOMAIN for gobject.

Bug 551887 – Docs for g_desktop_app_info_new_from_filename ()
aren't clear.
* gdesktopappinfo.c: add a note in the docs clarifying what the
"filename" parameter really is.

* glib/gutils.h
* glib/gwin32.h: Deprecate G_WIN32_DLLMAIN_FOR_DLL_NAME(),
g_win32_get_package_installation_directory() and
g_win32_get_package_installation_subdirectory() as their
documentation has warned for a while. Sorry that I forgot to do
this before 2.18.0.
* glib/gwin32.c (g_win32_get_package_installation_directory):
Print a warning if a non-NULL package parameter is passed to this
function, as that is deprecated usage, as the documentation says.

* gwin32appinfo.c (g_win32_app_info_launch): Don't call
FormatMessage() etc here. Call g_win32_error_message() instead
which already does all that. Besides, the code was broken as it
called the default "A" version of FormatMessage() but still
thought it produced a wide string.

Bug 551228 – G_STRFUNC on recent Sun compiler should be expanded to

by Paul Smith, fix proposed by Owen Taylor.
