ee55677086 Assorted portability enhancements (#1800)
* Introduce some Platform calls for managing dynamic libraries

* Add Platform::WriteFATSectors

* Introduce some Platform calls for managing dynamic libraries

* Add Platform::WriteFATSectors

* Change includes of "../types.h" to "types.h"

- Makes it easier to directly include these headers in downstream projects

* Change an include of "../Wifi.h" to "Wifi.h"

* Allow CommonFuncs.cpp to compile on Android

* Tidy up some logging calls

- Use Platform::Log in LAN_Socket.cpp
- Soften some warnings to Debug logs (since they don't necessarily represent problems)

* Add Platform::EnterGBAMode

- Gracefully stop the emulator if trying to enter GBA mode

* Soften some logs that most players won't care about

* Soften some more logs

* Introduce Platform wrappers for file operations

* Fix pointer spacing

* Fix more style nits

* Log the errno when ftruncate fails

* Fix FileSeek offset argument

- With an s32 offset, we couldn't access files larger than 2GB

* Revise Platform::StopEmu to address feedback

- Remove Platform::EnterGBAMode in favor of adding a reason to Platform::StopEmu
- Also rename Platform::StopEmu to Platform::SignalStop
- Add an optional argument to NDS::Stop
- Use the new argument everywhere that the console stops itself

* Rename FileGetString to FileReadLine

- It conveys the meaning better

* Rename FileSeekOrigin::Set to Start

- It conveys the meaning better

* Change definition of FileGetString to FileReadLine

- Oops, almost forgot it

* Rename FlushFile to FileFlush

- To remain consistent with the other File functions

* Add a FileType usage

* Fix line break in FileSeekOrigin

* Document Platform::DeInit

* Clarify that StopReason::Unknown doesn't always mean an error

* Move and document FileType::HostFile

* Remove Platform::OpenDataFile

- Nothing currently uses it

* Refactor Platform::OpenFile and Platform::OpenLocalFile to accept a FileMode enum instead of a string

- The enum is converted to fopen flags under the hood
- The file type is used to decide whether to add the "b" flag
- Some helper functions are exposed for the benefit of consistent behavior among frontends
- Equivalent behavior is maintained

* Fix a tab that should be spaces

* Use Windows' 64-bit implementations of fseek/ftell

* Move Platform::IsBinaryFile to Platform.cpp

- It could vary by frontend

* Remove an unused FileType

* Rename an enum constant

* Document various Platform items

* Use Platform::DynamicLibrary to load libandroid

- And clean it up at the end

* Fix a typo

* Pass the correct filetype to FATStorage

- Since it can be used for DSI NAND images or for SD cards

* Remove Platform::FileType

613280d3b4 DSi power button and volume switch support (#1630)

b1e4bd5520 merge local_wifi (#1516)
* attempt at betterer wifi

* add preliminary sync mechanism
* fix gaps in wifi implementation

* move local-MP comm to its own module instead of cramping Platform.cpp

* remove some stupid cruft

* as you wish, Sorer

(starting work on shared-memory system)

* shared-memory IPC that actually works (albeit Windows-only for now)

* shut up logging from NULL writes on ARM7 (ffs Nintendo learn to code)

* get this somewhat good

* leave client sync mode when host deauths. makes download play actually work.

* start implementing MP-comm error handling

* * add MP-reply error counters
* feeble attempt at fixing slowdown/desync/etc problems

* somewhat better exchange/sync method

* * when entering power-saving mode, be sure to finish transferring the current frame first
* fix misc bug due to old cruft leftover

makes for a more stable connection

* remove a bunch of cruft

* set wifi time interval to 34 cycles instead of 33. games seem sensitive to the general timing of wifi vs the rest of the system, and this seems to make things run better, atleast until I rewrite this to use a proper scheduler.

* more graceful handling of disconnects

* deal with FIFO overflow more gracefully

* BAHAHAHAHAHAHAHAHHHH

THE SNEAKY BASTARDS

so, when the DS receives a beacon with the right BSSID

that beacon's timestamp is copied to USCOUNTER

* attempt at making the connection process smoother for weird games

* * begin adding POWCNT2, only applies to wifi for now
* begin work on wifi scheduler

* implement the shitty timers

* add the RF wakeup thing

* begin work on receiving frames. for now it can just receive melonAP beacons, but hey, it's a start.

* add enough TX functionality that online wifi is a possibility again.

* there are problems with this scheduler thing. committing it anyway

* kind of a rollback... we're gonna work out a compromise on this, I guess

* don't transmit shit if RXCNT.bit15 isn't set

* move RX-finish to its own function. more accurate filtering. implement RXFILTER.

* remove some cruft

* fix some of the shittiness when trying to connect more than two players

* fix some more shittiness

* fix more wifi shittiness (mainly don't try to receive shit while sending a frame)

* run wifi every 8µs. improves performance.

* fix IRQ14/IRQ15

* make this work under Linux

* Make it work on macOS, for now using a custom sem_timedwait
implementation.

If anyone knows anything about mach ports and have an idea for how to
make this work using mach IPC, please do let me know.

* 25ms seems like a good timeout

* begin work on proper multiplayer UI shito.

for now, determine a global instance ID, and derivate the system MAC from it. remove 'randomize MAC' option.

* finish removing RandomizeMAC

* lay groundwork for instance-unique config

* work some on the UI... make it not labelled Fart

* more UI work: make it explicit that some things are instance-unique

* separate firmware files for multiplayer instances

* make instances save to different save files, too

* more UI work, make things somewhat less shitty

* lay base for the multiplayer settings dialog

* actually hook up most of that dialog

* actually implement the fun audio settings

* ensure all the wifi shit is properly savestated and reset. properly update timings for the wifi region when wifi is disabled.

* add more fun labels

* * ignore WEP frames if WEP is off
* implement RX_LEN_CROP

* fake enough of WEP processing to make Inazuma Eleven work

* * do not copy more ROM banner data than actually needed
* avoid trying to read out of bounds if the banner offset is bad

* Fix oversight with the preferences action causing the build to fail on macOS

d20543c119 DMA timing renovation (#1207)
* make timers usable for measurement shito without being assfuckingly unreliable

* bürp

* Arisotura can you ever clean up your goddamn code

also regroup the timer code instead of having it split weirdly

* make the set-timing functions a tad less hacky

* congrats Arisotura you made an ass-enum

* add timing region tables, and separate timings for ARM9 DMA (exempt of 3c penalty)

* getting somewhere

* sdsdfs

* see, Arisotura, was it that hard? blarg.
