- Did a test build to ensure RA built
- Copied over to my FTPservU sources and ensured no compile issues there
Looks solid. A lot cleaner, too.

I used the code in `wiiu/` to bootstrap my own WiiU homebrew app; this
PR reflects some changes I needed to make, that might be useful upstream.
1. Clean up filesystem initialization
Filesystem driver initialization was lumped in with filesystem mounting;
and that was a problem in my project, because I needed to be able to remount
the SD card on the fly. So, now it's split up.
I've added a callback object named "hooks" that can be used by consuming
applications to handle filesystem mounting and unmounting. If these hooks are
not provided, then the existing default behavior occurs.
2. Expand socket handling
- add `SO_NONBLOCK` flag for non-blocking socket I/O
- add normal errno defines like `EWOULDBLOCK` `EAGAIN`.
3. Remove RetroArch dependencies
- the exception handler protects usage of version_git with
`#ifdef HAVE_GIT_VERSION` but not the include, so I added that.
It also technically depends on version.h, but I'm not touching that.
It's easy enough to implement and I needed the same functionality. I'm
not sure what the best solution for that dependency is.
- missing_libc_functions.c included features/features_cpu.h which is
a libretro include. This appears to be a stale include though, because
everything compiles and works without it.
- an ifdef referencing the RA "WIIU" define, rather than the devkitpro
"__wiiu__" define
== DETAILS
We had some disagreement on what packet size to use.
The maximum packet size varies depending on the actual network
hardware in use; the typical Ethernet value is relatively safe,
but not 100% compatible.
RFC 791 does, however, define a minimum datagram size that all
IP hosts must be able to handle--and it's large enough for our
needs, since we're generally not writing more than maybe 100
bytes at a time anyway.
I also did a little bit of cleanup for readability.

The broadcast address is a standard part of TCP/IP that is used to
send messages to everyone on the subnet. This patch updates the
logging code to do the following:
1. Derive the broadcast address from the Wii U's own IP address
and subnet mask. These can all be obtained at runtime, which
means we can...
2. Remove the PC_DEVELOPMENT_IP_ADDRESS define from Wii U's
Makefile, because compiling in an IP is no longer needed.
3. Rewrite the net_listen script to listen for broadcast packets
and print them out with timestamps.
Since it's using the broadcast address, the only requirement is
that the PC be on the same network subnet as the Wii U.
Because of the low overhead of UDP, I've made logging on by
default. This will make it a ton easier to get useful bug
reports from users.
- move non-salamander objects out of salamander scope
- move the missing libc functions to general scope
- fix salamander_main inline invocation
TESTING: Ran 'make -f Makefile.wiiu SALAMANDER=1' successfully
=== DETAILS
Since @aliaspider wants the `wiiu/` to be something of a mini-SDK, I've
reorganized the code I put in there:
- `wiiu/main.c` now only has the ELF/RPX entrypoints, and the code used
by those entrypoints, with RA code removed (e.g. swapped retro_sleep()
for usleep()). These entrypoints then call main() ...
- Moved `main()` and its support functions back into `frontend/drivers/platform_wiiu.c`
I also renamed some of the support functions I wrote, and better
organized them within the code.
- Moved `wiiu/input/` into the `input/` hierarchy:
* The joypad drivers now live in `input/drivers_joypad/wiiu/`
* The HID driver now lives in `input/drivers_hid/`
* The Wii U specific headers now live in `input/include/wiiu`
* I added `input/include` into the include search path to avoid
using really ugly relative includes
== DETAILS
The Wii U main entrypoints were embedded in the frontend driver,
which isn't a great place for them. Also, the `main()` method was
pretty long and monolithic. Now it's (much) less so.
Changes:
- Refactor out the main entrypoints into their own source files
(`wiiu/main.c` and `wiiu/main.h`)
- Optimize includes in both files, so only the minimum needed to
compile are included.
- The `main()` method is a lot easier to understand now. It's no longer
a confusing mess of ifdefs.
- There's a small amount of changes in the headers for future work, which
is switching kpad_driver to be callback-driven. The only change here is
to import the function that will be used, and define some data types.
Testing:
- Did local builds and confirmed build is successful
- Successfully loaded a core and switched among a few games
Add some timing functions so that we can know the time (woo-hoo?)
I use errno here, which worries me a bit. I wouldn't put it past
devkitPPC to have it as a null pointer or something.
Can confirm this makes XMB's clock work, much to @cucholix's delight;
I'm sure ;D
