Implement client-side wallet

[kaetemi]

Bypass account creation, instead go through a wallet creation/import flow.

Server should just create a dummy account if the client can correctly sign a message for the wallet.

Wallet libraries

• https://github.com/ethereum/aleth

To build Aleth on Visual Studio 2022:

cmake -DHUNTER_MSVC_VERSION=17 -DHUNTER_MSVC_YEAR=2022 -DHUNTER_MSVC_ARCH=amd64 "-DHUNTER_MSVC_VCVARSALL=C:\\Program Files\\Microsoft Visual Studio\\2022\\Professional\\VC\\Auxiliary\\Build\\vcvarsall.bat" ..

Hunter seems to give errors, so better to do a custom build.

Dependencies:

• boost (official build)
• jsoncpp https://github.com/open-source-parsers/jsoncpp (cmake)
• snappy https://github.com/google/snappy (cmake)
• cryptopp https://github.com/weidai11/cryptopp (vs sln)
• libjson-rpc-cpp https://github.com/cinemast/libjson-rpc-cpp (cmake)
• libscrypt https://github.com/technion/libscrypt (windows hostile)
• ethash https://github.com/ethereum/ethash

For VS 2019:

cmake -G "Visual Studio 16 2019" ..
cmake --build .

This one seems to build so far.

Wallet Core doesn't have Windows support yet, so useless.

[kaetemi]

Wallet Core seems more appropriate, though. May be possible to just port it to Windows quickly.

Wallet Core ported to Windows, seems to run fine.

• [x] Build dynamic TrustWalletCore dll
• [x] Switch to static protobuf
• [x] Disable zlib in the protobuf configuration, don't need it
• Get unit tests building
