During debugging, the debug client may request to malloc a memory space
to evaluate the user expressions. If we malloc memory from the linear memory,
it may fail when the thread is in stop status. We preserve a buffer during
creating debug instance, and use a simple bump pointer allocator to serve lldb's
memory request.
In thread_manager.c, `wasm_cluster_spawn_exec_env` creates a new module
instance but not sets wasi_ctx, so when the new exec_env calls wasm function
which uses WASI API, the WASI API functions in `libc_wasi_wrapper.c` will get
null result in calling `get_wasi_ctx` and then return `wasi_errno`.

Refer to [Networking API design](https://github.com/WebAssembly/WASI/issues/370)
and [feat(socket): berkeley socket API v2](https://github.com/WebAssembly/WASI/pull/459):
- Support the socket API of synchronous mode, including `socket/bind/listen/accept/send/recv/close/shutdown`,
the asynchronous mode isn't supported yet.
- Support adding `--addr-pool=<pool1,pool2,..>` argument for command line to identify the valid ip address range
- Add socket-api sample and update the document
Implement pthread_cond_broadcast wrapper for lib-pthread
- support pthread_cond_broadcast wrapper for posix/linux-sgx/windows
- update document for building multi-thread wasm app with emcc
Fix __wasi_subscription_t structure definition inconsistent with wasi-libc
definition issue, reported by #961, tested with sleep, poll API and other
wasi cases on x86-64, x86-32 and arm32 targets.
Fix the issue that joining a detached thread might result in joining hang,
resolve the issue by adding wait_count for a thread's exec_env to indicate
whether a thread needs to detach itself or not when it exits.
And add checks for the input exec_env for cluster's join/detach/cancel thread.
- use platform independent data types in debug-engine library
- add os_socket APIs and provide windows and posix implementation
- avoid using platform related header files in non-platform layer
- use format specifiers macros for sprintf and sscanf
- change thread handle type from uint64 to korp_tid
- add lock when sending socket packet to avoid thread racing
Use `PRIxxx` related macros to format the output strings so as to clear
compile warnings, e.g. PRIu32, PRId32, PRIX32, PRIX64 and so on.
And add the related macro definitions in platform_common.h if they
are not defined, as some compilers might not support them.
Refine some codes in wasm loader
Add -Wshadow to gcc compile flags and fix some variable shadowed issues
Fix function parameter/return types not checked issue
Fix fast-interp loader reserve_block_ret() not handle V128 return type issue
Fix mini loader load_table_segment_section() failed issue
Add detailed comments for argc argument in wasm_runtime_call_wasm()
- move the wait_cond from exec_env to debug_instance, so the debug thread can be waken up by any threads
- process more general query message from debugger
- refine debug instance create/destroy mechanism
- avoid creating debug instance during module instantiating
- avoid blocking execution thread during creating debug instance
- update related documents
The debug_instance_list is not protected by mutex, and the debug instance uses
the length of this list as its id. If several threads create debug instance at the
same time, they may get duplicated/same ids. This patch adds mutex to protect
this list.
The destroy_callback_list variable in thread_manager_destroy is not cleared.
When wamr is started as a task, after exiting and restarting, it will loop
endlessly in traverse_list.

- fix data race issue between debug control thread and main thread
- fix possible memory leaks in breakpoints list
- fix memory uninitialized issues
- remove unused data structures
- add more checks when handling packet and args
- fix mini-loader issues

Implement source debugging feature for classic interpreter and AOT:
- use `cmake -DWAMR_BUILD_DEBUG_INTERP=1` to enable interpreter debugging
- use `cmake -DWAMR_BUILD_DEBUG_AOT=1` to enable AOT debugging
See doc/source_debugging.md for more details.
The last argument arg of pthread_create passed from wasm app is opaque
for the library and host, it should be returned back to the wasm app without
any interpretation. There is no point to translate it to a native address.
Actually it harms because the validation seems broken.

Some libc APIs required by wasi native lib are missing in some Android API versions, only when the version >= 24, all APIs are supported. Add the missing APIs in android platform layer, leave them empty, report error and return failed if they are called. Also update CMakeLists.txt to enable libc wasi by default.
