sprofile: various correctness fixes.

crypto: implement md5, which now used by sprof

ams: improve offsetof style consistency

sdmmc: use m_ for member variables

exo/vapours: refactor member variables to m_ over this->

ams: replace most remaining operator & with std::addressof

libstrat: enable -Wextra, -Werror ...

This caught an embarrassingly large number of bugs.

ams: the copyright^H^H^H^H^H^H^Hmplex plane is the algebraic closure of the reals

os: adopt multiwait naming over waitable

stratosphere: use SdkMutex/SdkRecursiveMutex over Mutex

ams-libs: AMS_ASSERT no longer invokes expression

LogManager: implement system module, client api, logging api (#1617) ...

Some notes:

* Unless `atmosphere!enable_log_manager` is true, Nintendo's log manager will be used instead.
  * This prevents paying memory costs for LM when not enabling logging.
  * To facilitate this, Atmosphere's log manager has a different program id from Nintendo's.
  * `atmosphere!enable_htc` implies `atmosphere!enable_log_manager`.
* LogManager logs to tma, and the SD card (if `lm!enable_sd_card_logging` is true, which it is by default).
* Binary logs are saved to `lm!sd_card_log_output_directory`, which is `atmosphere/binlogs` by default.
