WIP: expose ChannelManager from bindings crate to ffi

update bindings

udpate bindings to not expose result type as FFI

update

prepare FFIResult

finish tests for FFIResult

prepare thread_handle

prepare is_null

prepare all FFI handler type

avoid all compiler error by using ARc

separate adaptor types into adaptors folder

add BufferToSmall error case to FFIResult kind

Add new entrypoints for fetching and testing last result for FFI

add entrypoint for testing

remove input argument from test ffi

update

amend

update

udpate broadcaster_wrapper ffi interface

update

cleanup: rename variables and remove unused deps

remove unused cbindgen.toml

delete outdated readme message

do not specify repr(C) to Record type

Add `UnwandSafe` and `RefUnwindSafe` trait bound

* `Logger` and `ChainWatchInterface` were trait which has to cross ffi boundary.
  for a foreign language to catch a panic caused in `rust-lightning` these two
  traits must be `UnwindSafe` so explicitly add.

Fix miscs

* Use usize everywhere for len
* Use `OutPoint` from lightning instead of bitcoin

udpate comment

start writing ffi interface for testing logger

fix bug that FFITransaction points to garbage location

Remove unused `&Self` parameter from FFI delegate.

update

add entrypoint for releasing channel manager

remove unused test function

fix bug in FFIChainWatchInterface Constructor

Revert "remove unused test function"

This reverts commit 4a1cccb.

add new entrypoint send_payment

fix bug in broadcaster

stop receiving SafeHandle twice

take everything as delegate in constructor

* Since otherwise it sometimes crashes by GC in C# side.

cleanup

stop using debug_assertions as a feature

remove some unused imports and implement Error trait for APIError

Simplify FFIRoute

* When passing struct through FFI boundary, if the object
  has nested array it will cause headache for preventing it
  from GCed.
  So we just pass binary serialized object and (de)serialize after
  passing. In this case, `FFIRoute`.
* Prepare Debug trait for Route object.

add entrpoint for getting pending events from chanman

update: FFI PeerManager create/dispose methods

add deep_copy method to array_struct

update

remove unnecessary dirty tests

update: add process_event function for FFI

remove repr(C) from lightning pcakge

fix build error in lightning

update ffi for BasicMPP

fix some compiler warning

return Bool from read_event

Simplify ChainWatchInterface

* delegate some `FFIChainWatchInteface`'s work to `ChainWatchInterfaceUtil`
* remove now-useless ChannelMonitor and its related functions, objects

refactor create_channel_manager to be more generic

fix bug in deep_copy

return internal_error directly when converting FFI pub/secret key

stop using wacky deep_copy method

return act_one when calling new_outbound from C#

stop using FFIBytes for return value of new_outbound

simplify array_struct by not using generics

expose PeerManager::get_peer_node_ids to ffi

fix build error after rebasing to master

give channel maanger from outside world when initializing PeerManager

add many ffi entrypoints for ChannelManager
