Thomas Winget 4c630e0437 Large collection of changes to make android work 
- Previous android java and jni code updated to work, but with much love
  still needed to make it work nicely, e.g. handling when the VPN is
  turned off.

- DNS handling refactored to allow android to intercept and handle DNS
  requests as we can't set the system DNS to use a high port
  (and apparently Chrome ignores system DNS settings anyway)

- add packet router structure to allow separate handling of specific
  intercepted traffic, e.g. UDP traffic to port 53 gets handled by our
  DNS handler rather than being naively forwarded as exit traffic.

- For now, android lokinet is exit-only and hard-coded to use exit.loki
  as its exit.  The exit will be configurable before release, but
  allowing to not use exit-only mode is more of a challenge.

- some old gitignore remnants which were matching to things we don't
  want them to (and are no longer relevant) removed

- some minor changes to CI configuration

Thomas Winget a91bb35dbf
Some Windows fixes (#1415) 
* Should fix some windows service issues

* fix return condition inversion

* Add some Trace level logging

also make the logger actually respect the log level you set.

* event loop should not queue things to itself...

at present, logic thread queue continues until it is empty, so
queueing things onto itself is just wasteful.

* call_later(foreach thing) is better than foreach thing (call later)

also if you already queued those things but they have not happened yet,
there is no sense to queue them to happen again.

* do not queue read on write finish, only on read finish

* failure to start DNS server should be proper startup failure.

without the DNS server working lokinet is...kinda pointless, right?

* format

* don't queue stuff to logic thread if in logic thread
the thing that clears the queue...clears it.  So you're just delaying and adding overhead.

* windows unbound thread sleep instead of just busy-waiting

also clang-format decided I can't have a blank line for some reason...

* fix unbound async worker on windows

LNS (#1342) 
* initial relay side lns

* fix typo

* add reserved names and refactor test for dns

* lns name decryption

* all wired up (allegedly)

* refact to use service::EncryptedName for LNS responses to include nonce with ciphertext

* fully rwemove tag_lookup_job

* replace lns cache with DecayingHashTable

* check for lns name validity against the following rules:

* not localhost.loki, loki.loki, or snode.loki

* if it contains no dash then max 32 characters long, not including the .loki tld (and also assuming a leading subdomain has been stripped)

* These are from general DNS requirements, and also enforced in
registrations:

* Must be all [A-Za-z0-9-]. (A-Z will be lower-cased by the RPC call).

* cannot start or end with a -

* max 63 characters long if it does contain a dash

* cannot contain -- in the third and fourth characters unless it starts with xn--

* handle timeout in name lookup job by calling the right handler with std::nullopt

Thomas Winget b1c14af938
SRV Record handling for introsets (#1331) 
* update loki-mq submodule for tuple support

* srv record reply implementation

still need to encode srv records into intro sets / router contacts
as well as decode from them and match against queried service.proto

* inverted condition fix in config code

* SRV record struct (de-)serialization for intro sets

* parsing and using srv records from config (for/in introsets)

* adopt str utils from core and use for srv parsing

* changes to repeat requests

no longer drop repeat requests on the floor, but do not make
an *actual* request for them if one is in progress.

do not call reply hook for each reply for a request, as
each userland request is actually made into several lokinet
requests and this would result in duplicate replies.

* fetch SRVs from introsets for .loki

* make format

* dns and srv fixes, srv appears to be working

exit traffic via loki addresses 4 years ago
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.

- Move IPRange into its own net/ip_range.hpp

- Move the static net::IPPacket::TruncateV6, etc. functions to free
net::TruncateV6, etc. functions (now from net/ip.hpp instead of
net/ip_packet.hpp).

- Make net::TruncateV6 and net::ExpandV4 constexpr.

- Add IPRange::FromIPv4 factory function (to replace the iprange_ipv4
free function)

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.

Jason Rhinelander 6715b86d51 Fix IPv6 lookups to return empty response 
The logic here wasn't quite right and was returning an A record in
response to an AAAA lookup.

This returns nothing, which is better, but not quite enough: this gives
empty responses, which produces warnings in host/dig.

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)

Adds a TrimWhiteSpace instead of using abseil's.

Adds Catch2 tests for it, and also converts the existing str tests to
catch (which look much, much nicer than the gtest ones).
