svc: populate namespace

libstratosphere: use from /atmosphere/libraries

Improve exception wrapping

ams_mitm: Implement emummc Nintendo folder redirection

os/dd: primitive fixes

strat: TitleId -> ProgramId, titles->contents

strat: split out common functionality for future meso use

namespace sts -> namespace ams ...

namespace sts::ams -> ams::exosphere, ams::.

This is to facilitate future use of ams:: namespace code in
mesosphere, as we'll want to include ams::util, ams::result, ams::svc...

Results: Implement namespaced, type-safe results. ...

Because I was working on multiple things at once, this commit also:
- Adds wrappers for/linker flags to wrap CXX exceptions to make them
  abort. This saves ~0x8000 of memory in every system module.
- Broadly replaces lines of the pattern if (cond) { return ResultX; }
  with R_UNLESS(!cond, ResultX());.
- Reworks the R_TRY_CATCH macros (and the result macros in general).

libstrat: namespace remaining non-namespaced code. more new-ipc updates

spl: update for new-ipc (fixes two bugs in sf)

os: implement waitable management. ...

This implements waitable management for Events (and
implements Events). It also refactors PM to use new
Event/Waitable semantics, and also adds STS_ASSERT
as a macro for asserting a boolean expression. The
rest of stratosphere has been refactored to use
STS_ASSERT whenever possible.

libstrat: namespace hossynch.hpp

autobackup: dump bis keys (closes #583).

spl: rsa service does not need a dispatch table

strat: go all in on ncm::TitleId

Fix for 4.X units (new strato rework broke a method in spl) (#616) ...
