Optimized messages that were repetitive and added ability for core errors to specify more details optionally.

This was now mostly unused except by thread creation, which used a
symbol of the entrypoint, if available, to name the thread.

Appears to be currently broken, and given the complexity of doing this
for ARM code without debugging information, should probably be left to
an external tool or library. Use the GDB stub instead.

Closes #586

It has performance problems, a very misleading UI, and is broken in
general. It has essentially been superceded by the GDB stub, but if we
wanted a built-in disassembler in the future it'd essentially need to be
rewritten from scratch anyway.

Closes #427, #1480

* citra-qt: game list search function

* Empty search field during game list refresh

* Code improvements

* Code formatting

* Autofocus search field

* JayFoxRox's recommendations

* lioncash's review

Makes the initialization process a tad easier to grok,
since the constructor isn't just a glob of random unrelated behaviors.

3dsx and elf files default to system mode 2 (96MB allocated to the application).

This allows Home Menu to boot without modifications.
Closes #1849

Also minor style changes

This makes clang-format useful on those.

Also add a bunch of forgotten transitive includes, which otherwise
prevented compilation.

This also means : we have only one config file, now

Add error popup when citra initialization failed

Implement confirmation in a specific function
Fix typos and coding style

Coding convention
