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

strat: statically allocate additional threads

hipc: begin implementing domains. fixes ro + sm together

sf: implement service framework enough for ro to work. ...

This completely re-does the whole interface for ipc servers.

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.

strat: go all in on ncm::TitleId

stratosphere: all in on enum class CommandId

ro: refactor/rewrite into sts:: namespace

stratosphere: remove trailing whitespace

stratosphere: more result cleanup

ro: update for R_TRY usage

strat: disable exception handlers when creport would be better
