patch_manager: Return a std::unique_ptr from ParseControlNCA() and GetControlMetadata() instead of a std::shared_ptr

Neither of these functions require the use of shared ownership of the
returned pointer. This makes it more difficult to create reference
cycles with, and makes the interface more generic, as std::shared_ptr
instances can be created from a std::unique_ptr, but the vice-versa
isn't possible. This also alters relevant functions to take NCA
arguments by const reference rather than a const reference to a
std::shared_ptr. These functions don't alter the ownership of the memory
used by the NCA instance, so we can make the interface more generic by
not assuming anything about the type of smart pointer the NCA is
contained within and make it the caller's responsibility to ensure the
supplied NCA is valid.

 fsmitm_romfsbuild: Add support for stubbing and IPS patches in LFS

ips_layer: Add support for IPSwitch executable patches

Fixed assertion due to CountAddOnContent & Casting warnings

Unmapping an unmapped buffer should succeed

nso/nro: Add support for passing command-line arguments to executable

Hardware tests show that trying to unmap an unmapped buffer already should always succeed. Hardware test was tested up to 32 iterations of attempting to unmap

Uses -p (--program) and following string as args.

Only added if arguments string is non-empty and a pass is requested by loader.

Word count should be 3 since we're pushing a result code and a u32.

Also fixed up compiler warnings due to casting

loader: Add support for packed updates

gl_rasterizer: Implement accelerated Fermi2D copies.

Implemented Depth Compare, Shadow Samplers and Texture Processing Modes for TEXS and TLDS

Port citra-emu/citra#4311: "Remove "#" in the version number"

Port citra-emu/citra#4140: "misc input tab improvements"

Port citra-emu/citra#4312: "Update fmt to 5.2.1"

Ported #4296 from citra

gl_rasterizer: Fixup undefined behaviour in SetupDraw

Port citra-emu/citra#4313: "CONTRIBUTING.md - remove note about casting numeric types"

So that people can stop using it in issue/pr comments and randomly link some other issue/pr unintentionally.

Apparently it's not true: https://github.com/citra-emu/citra/pull/4310#discussion_r223174725

* Added a context menu on the buttons including Clear & Restore Default

* Allow clearing (unsetting) inputs. Added a Clear All button

* Allow restoring a single input to default (instead of all)

It seems to fix msvc warnings

qt: Update telemetry links

These were pointing to a non-existent webpage.

This will allow us to easily remove the use of "NFC" in "System"

Port web_service from Citra

kernel/mutex: Amend behavior of TransferMutexOwnership()

This was the result of a typo accidentally introduced in
e51d7157. This restores the previous
correct behavior.

The behavior with the reference was incorrect and would cause some games
to fail to boot.

ui_settings: Place definition of the theme array within the cpp file
