HLE/SRV: Implemented RegisterService.

* loader/ncch: split NCCH parsing into its own file

* loader/ncch: add support for loading update NCCHs from the SD card

* loader/ncch: fix formatting

* file_sys/ncch_container: Return a value for OpenFile

* loader/ncch: cleanup, always instantiate overlay_ncch to base_ncch

* file_sys/ncch_container: better encryption checks, allow non-app NCCHs to load properly and for the existence of NCCH structures to be checked

* file_sys/ncch_container: pass filepath as a const reference

* Services/UDS: Added a function to generate the EAPoL-Start packet body.

* Services/UDS: Added filter for beacons.

* Services/UDS: Lock a mutex when accessing connection_status from both the emulation and network thread.

* Services/UDS: Handle the Association Response frame and respond with the EAPoL-Start frame.

* fixup: make use of current_node, changed received_beacons into a list, mutex and assert corrections

* fixup: fix damn clang-format

Optimized Float<M,E> multiplication

Before:

ucomiss xmm1, xmm1
jp      .L9
pxor    xmm2, xmm2
mov     edx, 1
ucomiss xmm0, xmm2
setp    al
cmovne  eax, edx
test    al, al
jne     .L9
.L3:
movaps  xmm0, xmm2
ret
.L9:
ucomiss xmm0, xmm0
jp      .L10
pxor    xmm2, xmm2
mov     edx, 1
ucomiss xmm1, xmm2
setp    al
cmovne  eax, edx
test    al, al
je      .L3

After:

movaps  xmm2, xmm1
mulss   xmm2, xmm0
ucomiss xmm2, xmm2
jnp     .L3
ucomiss xmm1, xmm0
jnp     .L11
.L3:
movaps  xmm0, xmm2
ret
.L11:
pxor    xmm2, xmm2
jmp     .L3

GPU: Add draw for immediate and batch modes

Now system modules can do more than just crash immediately on startup.

Fixed framebuffer warning

Improved performance of FromAttributeBuffer

WebService: Set USE_SYSTEM_CURL for travis linux builds

* WebService: Verify username and token; Log errors in PostJson

* Fixup: added docstrings to the functions

* Webservice: Added Icons to the verification, imrpved error detection in cpr, fixup nits

* fixup: fmt warning

Ternary operator is optimized by the compiler
whereas std::min() is meant to return a value.

I've noticed a 5%-10% emulation speed increase.

Services/NS: Port ns:s to the new service framework.

PICA: implement custom clip plane

Kernel/Memory: Give each process its own page table and allow switching the current page table upon reschedule

CPU/Dynarmic: Disable the fast page-table access in dynarmic until it supports switching page tables at runtime.

This fixes building the tests

Kernel/Memory: Make IsValidPhysicalAddress not go through the current process' virtual memory mapping.

Kernel/Threads: Don't clear the CPU instruction cache when performing a context switch from an idle thread into a thread in the same process.

We were unnecessarily clearing the cache when going from Process A -> Idle -> Process A, this caused extreme performance regressions.

Kernel/Memory: Changed GetPhysicalPointer so that it doesn't go through the current process' page table to obtain a pointer.

APT: load different shared font depending on the region

Build: Enable SSL in mingw by linking against WinSSL

PR #1461 introduced a regression where some games would change configuration
even while in the poorly named "drawing" mode, which broke the heuristic
citra was using to determine when to draw the batch. This change adds
back in a draw call for batching, and also adds in a draw call in
immediate mode each time it adds a triangle.

The mingw builds aren't submitting telemetry because the curl library
they are linked against is configured to use openSSL and openSSL looks
for the certificates in the users home folder. This keeps it from
contacting web services because it can't communicate over SSL.

This commit adds a download in mingw builds that will download a
precompiled curl for mingw linked against winssl and sspi.

The loader is in charge of setting the newly created process's page table as the main one during the loading process.

travis_OSX: build with system curl

PICA: implemented geometry shader

Remove excess debug dlls for mingw build

pica/lighting: only apply Fresnel factor for the last light

Services/UDS: Handle beacon frames and the basic AP connection sequence frames.

Mii Selector Applet: update Mii structures
