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").
* Import cxxopts to replace getopts usage
* Add visual studio build things
* Fixup abseil build parts
* Replace __attribute__((unused)) with ABSL_ATTRIBUTE_UNUSED
* Fixup minor windows build issues
* Replace getopts usage
* Temporarily fixup .rc files
* More minor windows fixes
* Get a working build
* Revert .rc files
* Revert changes to nodedb
(with its now-obsolete distinction between socketfd and fd)
sockets and file descriptors used to be distinct objects....back in the
16-bit Winsock 1.1 era, which needlessly complicated the 32-bit port
back then. these days one can use [Read|Write]File(2) to operate on
sockfds...which also have some of the semantics of [read|write]v(2)
i.e. the scatter-gather thing it's known for is done in async handler
-rick
variants are nice
added note to self
clang-format
link abyss properly
oops
shut up
*shrugs*
oops forgot to start winsock
moved our async io status flags to the base class
let derived classes override them as needed
this is probably a synchronous op _anyway_
fix typo
wtf
