Refactor Router code into more classes This commit refactors functionality from the Router class into separate, dedicated classes. There are a few behavior changes that came as a result of discussion on what the correct behavior should be. In addition, many things Router was previously doing can now be provided callback functions to alert the calling point when the asynchronous action completes, successfully or otherwise.

De-abseil, part 2: mutex, locks, (most) time - util::Mutex is now a std::shared_timed_mutex, which is capable of exclusive and shared locks. - util::Lock is still present as a std::lock_guard<util::Mutex>. - the locking annotations are preserved, but updated to the latest supported by clang rather than using abseil's older/deprecated ones. - ACQUIRE_LOCK macro is gone since we don't pass mutexes by pointer into locks anymore (WTF abseil). - ReleasableLock is gone. Instead there are now some llarp::util helper methods to obtain unique and/or shared locks: - `auto lock = util::unique_lock(mutex);` gets an RAII-but-also unlockable object (std::unique_lock<T>, with T inferred from `mutex`). - `auto lock = util::shared_lock(mutex);` gets an RAII shared (i.e. "reader") lock of the mutex. - `auto lock = util::unique_locks(mutex1, mutex2, mutex3);` can be used to atomically lock multiple mutexes at once (returning a tuple of the locks). This are templated on the mutex which makes them a bit more flexible than using a concrete type: they can be used for any type of lockable mutex, not only util::Mutex. (Some of the code here uses them for getting locks around a std::mutex). Until C++17, using the RAII types is painfully verbose: ```C++ // pre-C++17 - needing to figure out the mutex type here is annoying: std::unique_lock<util::Mutex> lock(mutex); // pre-C++17 and even more verbose (but at least the type isn't needed): std::unique_lock<decltype(mutex)> lock(mutex); // our compromise: auto lock = util::unique_lock(mutex); // C++17: std::unique_lock lock(mutex); ``` All of these functions will also warn (under gcc or clang) if you discard the return value. You can also do fancy things like `auto l = util::unique_lock(mutex, std::adopt_lock)` (which lets a lock take over an already-locked mutex). - metrics code is gone, which also removes a big pile of code that was only used by metrics: - llarp::util::Scheduler - llarp::thread::TimerQueue - llarp::util::Stopwatch

De-abseil, part 2: mutex, locks, (most) time - util::Mutex is now a std::shared_timed_mutex, which is capable of exclusive and shared locks. - util::Lock is still present as a std::lock_guard<util::Mutex>. - the locking annotations are preserved, but updated to the latest supported by clang rather than using abseil's older/deprecated ones. - ACQUIRE_LOCK macro is gone since we don't pass mutexes by pointer into locks anymore (WTF abseil). - ReleasableLock is gone. Instead there are now some llarp::util helper methods to obtain unique and/or shared locks: - `auto lock = util::unique_lock(mutex);` gets an RAII-but-also unlockable object (std::unique_lock<T>, with T inferred from `mutex`). - `auto lock = util::shared_lock(mutex);` gets an RAII shared (i.e. "reader") lock of the mutex. - `auto lock = util::unique_locks(mutex1, mutex2, mutex3);` can be used to atomically lock multiple mutexes at once (returning a tuple of the locks). This are templated on the mutex which makes them a bit more flexible than using a concrete type: they can be used for any type of lockable mutex, not only util::Mutex. (Some of the code here uses them for getting locks around a std::mutex). Until C++17, using the RAII types is painfully verbose: ```C++ // pre-C++17 - needing to figure out the mutex type here is annoying: std::unique_lock<util::Mutex> lock(mutex); // pre-C++17 and even more verbose (but at least the type isn't needed): std::unique_lock<decltype(mutex)> lock(mutex); // our compromise: auto lock = util::unique_lock(mutex); // C++17: std::unique_lock lock(mutex); ``` All of these functions will also warn (under gcc or clang) if you discard the return value. You can also do fancy things like `auto l = util::unique_lock(mutex, std::adopt_lock)` (which lets a lock take over an already-locked mutex). - metrics code is gone, which also removes a big pile of code that was only used by metrics: - llarp::util::Scheduler - llarp::thread::TimerQueue - llarp::util::Stopwatch

De-abseil, part 2: mutex, locks, (most) time - util::Mutex is now a std::shared_timed_mutex, which is capable of exclusive and shared locks. - util::Lock is still present as a std::lock_guard<util::Mutex>. - the locking annotations are preserved, but updated to the latest supported by clang rather than using abseil's older/deprecated ones. - ACQUIRE_LOCK macro is gone since we don't pass mutexes by pointer into locks anymore (WTF abseil). - ReleasableLock is gone. Instead there are now some llarp::util helper methods to obtain unique and/or shared locks: - `auto lock = util::unique_lock(mutex);` gets an RAII-but-also unlockable object (std::unique_lock<T>, with T inferred from `mutex`). - `auto lock = util::shared_lock(mutex);` gets an RAII shared (i.e. "reader") lock of the mutex. - `auto lock = util::unique_locks(mutex1, mutex2, mutex3);` can be used to atomically lock multiple mutexes at once (returning a tuple of the locks). This are templated on the mutex which makes them a bit more flexible than using a concrete type: they can be used for any type of lockable mutex, not only util::Mutex. (Some of the code here uses them for getting locks around a std::mutex). Until C++17, using the RAII types is painfully verbose: ```C++ // pre-C++17 - needing to figure out the mutex type here is annoying: std::unique_lock<util::Mutex> lock(mutex); // pre-C++17 and even more verbose (but at least the type isn't needed): std::unique_lock<decltype(mutex)> lock(mutex); // our compromise: auto lock = util::unique_lock(mutex); // C++17: std::unique_lock lock(mutex); ``` All of these functions will also warn (under gcc or clang) if you discard the return value. You can also do fancy things like `auto l = util::unique_lock(mutex, std::adopt_lock)` (which lets a lock take over an already-locked mutex). - metrics code is gone, which also removes a big pile of code that was only used by metrics: - llarp::util::Scheduler - llarp::thread::TimerQueue - llarp::util::Stopwatch

De-abseil, part 2: mutex, locks, (most) time - util::Mutex is now a std::shared_timed_mutex, which is capable of exclusive and shared locks. - util::Lock is still present as a std::lock_guard<util::Mutex>. - the locking annotations are preserved, but updated to the latest supported by clang rather than using abseil's older/deprecated ones. - ACQUIRE_LOCK macro is gone since we don't pass mutexes by pointer into locks anymore (WTF abseil). - ReleasableLock is gone. Instead there are now some llarp::util helper methods to obtain unique and/or shared locks: - `auto lock = util::unique_lock(mutex);` gets an RAII-but-also unlockable object (std::unique_lock<T>, with T inferred from `mutex`). - `auto lock = util::shared_lock(mutex);` gets an RAII shared (i.e. "reader") lock of the mutex. - `auto lock = util::unique_locks(mutex1, mutex2, mutex3);` can be used to atomically lock multiple mutexes at once (returning a tuple of the locks). This are templated on the mutex which makes them a bit more flexible than using a concrete type: they can be used for any type of lockable mutex, not only util::Mutex. (Some of the code here uses them for getting locks around a std::mutex). Until C++17, using the RAII types is painfully verbose: ```C++ // pre-C++17 - needing to figure out the mutex type here is annoying: std::unique_lock<util::Mutex> lock(mutex); // pre-C++17 and even more verbose (but at least the type isn't needed): std::unique_lock<decltype(mutex)> lock(mutex); // our compromise: auto lock = util::unique_lock(mutex); // C++17: std::unique_lock lock(mutex); ``` All of these functions will also warn (under gcc or clang) if you discard the return value. You can also do fancy things like `auto l = util::unique_lock(mutex, std::adopt_lock)` (which lets a lock take over an already-locked mutex). - metrics code is gone, which also removes a big pile of code that was only used by metrics: - llarp::util::Scheduler - llarp::thread::TimerQueue - llarp::util::Stopwatch
