erpt: update server code for 16.0.0 logic changes

erpt: fix multiple issues with automatic report cleanup (thanks @yellows8) ...

* Setting retrieval was performed before the call that used the setting.
* Call to detect number of files passed incomplete path and was guaranteed to fail.
* Call to delete reports passed incomplete path and was guaranteed to do nothing.

ams: globally prefer R_RETURN to return for ams::Result

ams: use R_SUCCEED, R_THROW globally

ams: support building unit test programs on windows/linux/macos

erpt: add automatic report cleanup mechanism on boot (closes #1795)

ams: deduplicate static initialization logic

sf: prevent emitting mitm/defer code unless server in process supports it

strat: use m_ for member variables

erpt: save 8KB

strat: use ams::Main() instead of main(argc, argv)

libstrat: enable -Wextra, -Werror ...

This caught an embarrassingly large number of bugs.

strat: use sf::NativeHandle for ipc templating

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

os: adopt multiwait naming over waitable

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.
