Jason Rhinelander d05e6716cb Remove llarp::str(string_view) 
It was a workaround for pre-C++17 std::string which didn't support
passing a string_view to various functions/operators.  There's only one
place left that needs an explicit conversion, and that's where it is
used as a map key; so just be explicit there and remove llarp::str()
everywhere else.

Jason Rhinelander ebd2142114 Don't use std::optional::value() because f u macos 
This replaces all use of std::optional's `opt.value()` with `*opt`
because macOS is great and the ghost of Steve Jobs says that actually
supporting std::optional's value() method is not for chumps before macOS
10.14.  So don't use it because Apple is great.

Pretty much all of our use of it actually is done better with operator*
anyway (since operator* doesn't do a check that the optional has a
value).

Also replaced *most* of the `has_value()` calls with direct bool
context, except for one in the config section which looked really
confusing at a glance without a has_value().

Jason Rhinelander e470a6d73e C++17 niceties 
- class template argument deduction lets us write `std::unique_lock
  foo{mutex}` instead of `std::unique_lock<mutex_type> foo{mutex}` which
  makes the `unique_lock` and `shared_lock` functions unnecessary.

- Replace GNU-specific warn_unused_result attribute with C++17-standard
  [[nodiscard]]

The Great Wall of Blame 
This commit reflects changes to clang-format rules. Unfortunately,
these rule changes create a massive change to the codebase, which
causes an apparent rewrite of git history.

Git blame's --ignore-rev flag can be used to ignore this commit when
attempting to `git blame` some code.

Rick V b449e03f43
So as of GCC 9.2, std::random_device on Windows is RtlGenRandom() 
....which is precisely the thing i patch out in libsodium to use CryptoAPI
documented interfaces instead (which fall through to RtlGenRandom() on
such devices _anyway_)
we can just use libsodium directly, i happened to patch it out in libstdc++
as a side effect (since my local toolchain can target any version of windows)

Thomas Winget 68c1ae52b3 add ShortHex function to AlignedBuffer 4 years ago
Thomas Winget c9a278c0de some more changes to pybind/hive code, read below 
hive.py is currently largely for testing the pybind stuff, so changes to it will likely
be frequent and arbitrary for now.

Added pybind for llarp::path::PathHopConfig, but not every member -- just rc and upstream routerID

Hive now uses std::queue with mutex instead of our lockless queue.

Removed some functions from Hive that will not be necessary as things are being handled from python.

Thomas Winget 9b3bf833e0 revert nop logging -- un-revert later 4 years ago
Thomas Winget a5c2b369b7 nop logging on hive build for now 
a bunch of routers logging to stdout at the same time is a complete
charlie foxtrot.  until we take the time to make logger not a singleton
(and probably make each router able to log to its own file rather than stdout)
just make it not log.

Note: this is very temporary, as the logs will be annoying for testing the
pybind stuff and shouldn't be necessary for debugging it

Jason Rhinelander 3bd400f6fe Fix string_view C++17 compatibility 
string_view was implicitly convertible to std::string, but
std::string_view is only explicitly convertible.  This makes the
`operator std::string` explicit to be more compatible, and re-adds a
bunch of explicit string casts to the code where needed.

(This also fixes the build if changing the standard to c++17)

other constexpr methods here that use them).

Jason Rhinelander 2e9840ea39 Replace abseil date code with Hinnart's date.h 
Howard Hinnart's date.h is the library that was accepted as C++20
date/calendar support, so this is essentially a backport of C++20 date
time support.

(It does support timezone support, but requires more of the library and
that seems like overkill for what we need; this just prints UTC
timestamps instead, which need only a header-only include).

Jason Rhinelander 00a624ab40 Fix and rename CaselessCmp -> CaselessLessThan 
The comparison done here was really weird: by comparing lengths *before*
contents "zz" would sort before "aaa".  It wasn't invalid for the
specific purpose being used here (looking for true/false values), but
would be highly broken if someone tried to use it elsewhere.

Also renamed it because it really is just a `<` implementation, not a
full cmp implementation.

Jason Rhinelander f84ce61d66 Removed empty cpp files 
These aren't needed: CMake already knows how to follow #includes and
rebuild when headers change as long as the headers are included
*somewhere*.  The extra .cpp files here just require building a bunch of
.cpp files with just header content that we just end up throw away
during linking (since the same things will also be compiled in whatever
other compilation units include the same headers).

Jason Rhinelander fe61367a87 Vastly simplified llarp::util::memFn 
There is a huge pile of unnecessary machinery here that can be solved
with a few lambdas and some member function pointer type deduction.
 4 years ago
Jason Rhinelander b4440094b0 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:🧵:TimerQueue
  - llarp::util::Stopwatch

Jason Rhinelander 05a2e961e6 Add missing header 4 years ago
Jason Rhinelander ac1486d0be Replace absl::optional with optional-lite 
Step 1 of removing abseil from lokinet.

For the most part this is a drop-in replacement, but there are also a
few changes here to the JSONRPC layer that were needed to work around
current gcc 10 dev snapshot:

- JSONRPC returns a json now instead of an optional<json>.  It doesn't
  make any sense to have a json rpc call that just closes the connection
  with returning anything.  Invoked functions can return a null (default
  constructed) result now if they don't have anything to return (such a
  null value won't be added as "result").

Jason Rhinelander 3be7eb789b Endian defines fix for macOS 
It seems `__BYTE_ORDER`/`__LITTLE_ENDIAN`/`__BIG_ENDIAN` aren't defined
on macOS, so `if __BYTE_ORDER == __BIG_ENDIAN` was true which made macOS
take the big endian path *twice* (which cancelled out the big endian
conversion).

This makes util/endian.hpp define __LITTLE_ENDIAN__ or __BIG_ENDIAN__
everywhere, and errors if it can't be set.

Jason Rhinelander d57d6bfc6d Use memcpy to extract hash value 
Using the straight reinterpret_cast runs into type aliasing issues,
which manifest on armhf.  C++20 adds `std::bit_cast` to deal with
exactly this, but memcpy is the pre-C++20 way to do it properly.
