This synchronizes bsnes/higan with many recent internal nall changes.
This will be the last WIP until I am situated in Japan. Apologies for the
bugfixes that didn't get applied yet, I ran out of time.

Changelog:
- gb/mbc7: rewrote the 93LCx6 EEPROM emulation
- sfc/slot/bsmemory: rewrote the flash emulation for Satellaview
cartridges
As of this release, flash-based BS Memory cartridges will be writable.
So without the bsnes patch to disable write limits, some games will lock
out after a few plays.

Sigh ...
asio.hpp needs #include <nall/windows/registry.hpp>
[Since the last WIP, byuu also posted the following message. -Ed.]
ruby drivers have all been updated (but not tested outside of BSD), and
I redesigned the settings window. The driver functionality all exists on
a new "Drivers" panel, the emulator/hack settings go to a
"Configuration" panel, and the video/audio panels lose driver settings.
As does the settings menu and its synchronize options.
I want to start pushing toward a v107 release. Critically, I will need
DirectSound and ALSA to support dynamic rate control. I'd also like to
eliminate the other system manifest.bml files. I need to update the
cheat code database format, and bundle at least a few quark shaders --
although I still need to default to Direct3D on Windows.
Turbo keys would be nice, if it's not too much effort. Aside from
netplay, it's the last significant feature I'm missing.
I think for v107, higan is going to be a bit rough around the edges
compared to bsnes. And I don't think it's practical to finish the bsnes
localization support.
I'm thinking we probably want another WIP to iron out any critical
issues, but this time there should be a feature freeze with the next
WIP.

Changelog:
- added 30 new PAL games to icarus (courtesy of Mikerochip)
- new version of libco no longer requires mprotect nor W|X permissions
- nall: default C compiler to -std=c11 instead of -std=c99
- nall: use `-fno-strict-aliasing` during compilation
- updated nall/certificates (hopefully for the last time)
- updated nall/http to newer coding conventions
- nall: improve handling of range() function
I didn't really work on higan at all, this is mostly just a release
because lots of other things have changed.
The most interesting is `-fno-strict-aliasing` ... basically, it joins
`-fwrapv` as being "stop the GCC developers from doing *really* evil
shit that could lead to security vulnerabilities or instabilities."
For the most part, it's a ~2% speed penalty for higan. Except for the
Sega Genesis, where it's a ~10% speedup. I have no idea how that's
possible, but clearly something's going very wrong with strict aliasing
on the Genesis core.
So ... it is what it is. If you need the performance for the non-Genesis
cores, you can turn it off in your builds. But I'm getting quite sick of
C++'s "surprises" and clever compiler developers, so I'm keeping it on
in all of my software going forward.

Changelog:
- nall::lstring -> nall::string_vector
- added IntegerBitField<type, lo, hi> -- hopefully it works correctly...
- Multitap 1-4 -> Super Multitap 2-5
- fixed SFC PPU CGRAM read regression
- huge amounts of SFC PPU IO register cleanups -- .bits really is lovely
- re-added the read/write(VRAM,OAM,CGRAM) helpers for the SFC PPU
- but they're now optimized to the realities of the PPU (16-bit data
sizes / no address parameter / where appropriate)
- basically used to get the active-display overrides in a unified place;
but also reduces duplicate code in (read,write)IO
byuu says:
Changelog:
- nall/vector rewritten from scratch
- higan/audio uses nall/vector instead of raw pointers
- higan/sfc/coprocessor/sdd1 updated with new research information
- ruby/video/glx and ruby/video/glx2: fuck salt glXSwapIntervalEXT!
The big change here is definitely nall/vector. The Windows, OS X and Qt
ports won't compile until you change some first/last strings to
left/right, but GTK will compile.
I'd be really grateful if anyone could stress-test nall/vector. Pretty
much everything I do relies on this class. If we introduce a bug, the
worst case scenario is my entire SFC game dump database gets corrupted,
or the byuu.org server gets compromised. So it's really critical that we
test the hell out of this right now.
The S-DD1 changes mean you need to update your installation of icarus
again. Also, even though the Lunar FMV never really worked on the
accuracy core anyway (it didn't initialize the PPU properly), it really
won't work now that we emulate the hard-limit of 16MiB for S-DD1 games.

Nothing WS-related this time.
First, I fixed expansion port device mapping. On first load, it was
mapping the expansion port device too late, so it ended up not taking
effect. I had to spin out the logic for that into
Program::connectDevices(). This was proving to be quite annoying while
testing eBoot (SNES-Hook simulation.)
Second, I fixed the audio->set(Frequency, Latency) functions to take
(uint) parameters from the configuration file, so the weird behavior
around changing settings in the audio panel should hopefully be gone
now.
Third, I rewrote the interface->load,unload functions to call into the
(Emulator)::System::load,unload functions. And I have those call out to
Cartridge::load,unload. Before, this was inverted, and Cartridge::load()
was invoking System::load(), which I felt was kind of backward.
The Super Game Boy really didn't like this change, however. And it took
me a few hours to power through it. Before, I had the Game Boy core
dummying out all the interface->(load,save)Request calls, and having the
SNES core make them for it. This is because the folder paths and IDs
will be different between the two cores.
I've redesigned things so that ICD2's Emulator::Interface overloads
loadRequest and saveRequest, and translates the requests into new
requests for the SuperFamicom core. This allows the Game Boy code to do
its own loading for everything without a bunch of Super Game Boy special
casing, and without any awkwardness around powering on with no cartridge
inserted.
This also lets the SNES side of things simply call into higher-level
GameBoy::interface->load,save(id, stream) functions instead of stabbing
at the raw underlying state inside of various Game Boy core emulation
classes. So things are a lot better abstracted now.

New update. Most of the work today went into eliminating hiro::Image
from all objects in all ports, replacing with nall::image. That took an
eternity.
Changelog:
- fixed crashing bug when loading games [thanks endrift!!]
- toggling "show status bar" option adjusts window geometry (not
supposed to recenter the window, though)
- button sizes improved; icon-only button icons no longer being cut off

Changelog:
- GBA: lots of emulation improvements
- PPU PRAM is 16-bits wide
- DMA masks &~1/Half, &~3/Word
- VRAM OBJ 8-bit writes are ignored
- OAM 8-bit writes are ignored
- BGnCNT unused bits are writable*
- BG(0,1)CNT can't set the d13
- BLDALPHA is readable (fixes Donkey Kong Country, etc)
- SNES: lots of code cleanups
- sfc/chip => sfc/coprocessor
- UI: save most recent controller selection
GBA test scores: 1552/1552, 37/38, 1020/1260
(* forgot to add the value to the read function, so endrift's I/O tests
for them will fail. Fixed locally.)
Note: SNES is the only system with multiple controller/expansion port
options, and as such is the only one with a "None" option. Because it's
shared by the controller and expansion port, it ends up sorted first in
the list. This means that on your first run, you'll need to go to Super
Famicom->Controller Port 1 and select "Gamepad", otherwise input won't
work.
Also note that changing the expansion port device requires loading a new
cart. Unlike controllers, you aren't meant to hotplug expansion port
devices.

Changelog:
- added Cocoa target: higan can now be compiled for OS X Lion
[Cydrak, byuu]
- SNES/accuracy profile hires color blending improvements - fixes
Marvelous text [AWJ]
- fixed a slight bug in SNES/SA-1 VBR support caused by a typo
- added support for multi-pass shaders that can load external textures
(requires OpenGL 3.2+)
- added game library path (used by ananke->Import Game) to
Settings->Advanced
- system profiles, shaders and cheats database can be stored in "all
users" shared folders now (eg /usr/share on Linux)
- all configuration files are in BML format now, instead of XML (much
easier to read and edit this way)
- main window supports drag-and-drop of game folders (but not game files
/ ZIP archives)
- audio buffer clears when entering a modal loop on Windows (prevents
audio repetition with DirectSound driver)
- a substantial amount of code clean-up (probably the biggest
refactoring to date)
One highly desired target for this release was to default to the optimal
drivers instead of the safest drivers, but because AMD drivers don't
seem to like my OpenGL 3.2 driver, I've decided to postpone that. AMD
has too big a market share. Hopefully with v093 officially released, we
can get some public input on what AMD doesn't like.
