PoC Smart Escrows (#5340)
* wasmedge in unittest * add WashVM.h and cpp * accountID comparison (vector<u8>) working * json decode tx and ledger object with two buffers working * wasm return a buffer working * add a failure test case to P2P3 * host function return ledger sqn * instruction gas and host function gas * basics * add scaffold * add amendment check * working PoC * get test working * fix clang-format * prototype #2 * p2p3 * [WIP] P4 * P5 * add calculateBaseFee * add FinishFunction preflight checks (+ tests) * additional reserve for sfFinishFunction * higher fees for EscrowFinish * rename amendment to SmartEscrow * make fee voting changes, add basic tests * clean up * clean up * clean up * more cleanup * add subscribe tests * add more tests * undo formatting * undo formatting * remove bad comment * more debugging statements * fix clang-format * fix rebase issues * fix more rebase issues * more rebase fixes * add source code for wasm * respond to comments * add const --------- Co-authored-by: Peng Wang <pwang200@gmail.com>
