fs.mitm: Save memory+time in sibling reconstruction via reverse iteration

fs.mitm: Optimize out remaining O(n^2) op. BotW is very fast.

fs.mitm: Fix typo. map impl takes 2-3 seconds to boot botw.

fs.mitm: Use std::map for RomFS building

fs.mitm: Fix debug-commented-out command

fs.mitm: Simplify source merging condition thanks to padding guarantees

fs.mitm: Use less path memory, fix source concat. (Fixes BotW, probably others)

fs.mitm: Fix c++ modernization breaking changes

creport: Add dying message to output report, if relevant.

creport: Complete crash report saving.

creport: Clean up bugs, now saves (empty) reports to the SD successfully

creport: Fix bad constructor for ThreadInfo

creport: fix a bunch of trivial errors

creport: fix typo in json

creport: Further Skeleton Report saving.

creport: Implement reading name/build id from .rodata

creport: Skeleton reading of Code Regions.

creport: fix thread_list access style

creport: Implement reading info about all threads.

creport: Implement reading a dying message

creport: Parse info for crashed thread

creport: Read exception info properly (except for crashed thread info)

creport: Solidify main() logic.

creport: Implement process open, stub exception parsing.

creport: Further skeleton the CrashReport object.

creport: Add skeleton. Doesn't actually generate reports yet.

Loader: Fix argument passing.

libstratosphere: Cleanup resources when doing OutSession for domains.

Modernize C++ usage (#144) ...

* Stratosphere: Use modern C++ idioms in some places

* algorithms like std::for_each are used instead of raw loops

* Stratosphere: Replace more raw loops with algorithms

* Stratosphere: Add a utility predicate function to test for equality with a reference element

This can be used to rewrite some common raw loops using algorithms instead

* fs.mitm: Use variant

* fs.mitm: Use enum class

* fs.mitm: Turn RomFSSourceInfo::Cleanup into a destructor

This obsoletes the need for a custom deleter in other places

* fs.mitm: Use enum class some more

* fs.mitm: Use unique_ptr

* fs.mitm: Simplify initialization

* Stratosphere: Simplify initialization

* fs.mitm: Use unique_ptr (fix memory leak along the way)

The previous code was using "delete" rather than "delete[]"

* fs.mitm: Use vector::emplace_back rather than push_back

emplace_back constructs elements in-place, hence avoiding a redundant element copy.

* Stratosphere: Replace more raw loops with algorithms

* Stratosphere: Use unique_ptr

* fs.mitm: Replace more raw loops with algorithms

* Stratosphere: Prefer move-construction over copy-construction when moving sink parameters around

PM: Fix remaining issues, now works properly again.
