do not run run the tsan + openssl test on ci

Client code:

    ...

    ix::WebSocketHttpHeaders headers {
        {"Cookie", "ABC"}
    };

    ...

Expected header string on server:
    "Cookie: ABC"

Resulted header string on server:
    "Cookie: BC"

Solution:
    The easy way I found to solve the problem is to add a space where extra headers are set before sended to server.

 Connections can be optionally secured and encrypted with TLS/SSL when using a wss:// endpoint, or using normal un-encrypted socket with ws:// endpoints. AppleSSL is used on iOS and macOS, OpenSSL and mbedTLS can be used on Android, Linux and Windows.
 
+If you are using OpenSSL, try to be on a version higher than 1.1.x as there there are thread safety problems with 1.0.x.

 ### Polling and background thread work
 
 No manual polling to fetch data is required. Data is sent and received instantly by using a background thread for receiving data and the select [system](http://man7.org/linux/man-pages/man2/select.2.html) call to be notified by the OS of incoming data. No timeout is used for select so that the background thread is only woken up when data is available, to optimize battery life. This is also the recommended way of using select according to the select tutorial, section [select law](https://linux.die.net/man/2/select_tut). Read and Writes to the socket are non blocking. Data is sent right away and not enqueued by writing directly to the socket, which is [possible](https://stackoverflow.com/questions/1981372/are-parallel-calls-to-send-recv-on-the-same-socket-valid) since system socket implementations allow concurrent read/writes. However concurrent writes need to be protected with mutex.

 ## Limitations
 
-* On Windows and Android certificate validation needs to be setup so that SocketTLSOptions.caFile point to a pem file, such as the one distributed by Firefox. Unless that setup is done connecting to a wss endpoint will display an error. On Windows with mbedtls the message will contain `error in handshake : X509 - Certificate verification failed, e.g. CRL, CA or signature check failed`.
-* There is no convenient way to embed a ca cert.
+* On some configuration (mostly Android) certificate validation needs to be setup so that SocketTLSOptions.caFile point to a pem file, such as the one distributed by Firefox. Unless that setup is done connecting to a wss endpoint will display an error. With mbedtls the message will contain `error in handshake : X509 - Certificate verification failed, e.g. CRL, CA or signature check failed`.
 * Automatic reconnection works at the TCP socket level, and will detect remote end disconnects. However, if the device/computer network become unreachable (by turning off wifi), it is quite hard to reliably and timely detect it at the socket level using `recv` and `send` error codes. [Here](https://stackoverflow.com/questions/14782143/linux-socket-how-to-detect-disconnected-network-in-a-client-program) is a good discussion on the subject. This behavior is consistent with other runtimes such as node.js. One way to detect a disconnected device with low level C code is to do a name resolution with DNS but this can be expensive. Mobile devices have good and reliable API to do that.
 * The server code is using select to detect incoming data, and creates one OS thread per connection. This is not as scalable as strategies using epoll or kqueue.

 Specifying `caFile` configures the trusted roots bundle file (in PEM format) that will be used to verify peer certificates.
  - The special value of `SYSTEM` (the default) indicates that the system-configured trust bundle should be used; this is generally what you want when connecting to any publicly exposed API/server.
  - The special value of `NONE` can be used to disable peer verification; this is only recommended to rule out certificate verification when testing connectivity.
+ - If the value contain the special value `-----BEGIN CERTIFICATE-----`, the value will be read from memory, and not from a file. This is convenient on platforms like Android where reading / writing to the file system can be challenging without proper permissions, or without knowing the location of a temp directory.
 
 For a client, specifying `caFile` can be used if connecting to a server that uses a self-signed cert, or when using a custom CA in an internal environment.

+// API Summary:
+//
+// LuaWrapper is a library designed to help bridge the gab between Lua and
+// C++. It is designed to be small (a single header file), simple, fast,
+// and typesafe. It has no external dependencies, and does not need to be
+// precompiled; the header can simply be dropped into a project and used
+// immediately. It even supports class inheritance to a certain degree. Objects
+// can be created in either Lua or C++, and passed back and forth.
+//
+// The main functions of interest are the following:
+//  luaW_is<T>
+//  luaW_to<T>
+//  luaW_check<T>
+//  luaW_push<T>
+//  luaW_register<T>
+//  luaW_setfuncs<T>
+//  luaW_extend<T, U>
+//  luaW_hold<T>
+//  luaW_release<T>
+//
+// These functions allow you to manipulate arbitrary classes just like you
+// would the primitive types (e.g. numbers or strings). If you are familiar
+// with the normal Lua API the behavior of these functions should be very
+// intuative.
+//
+// For more information see the README and the comments below

+// generally for things you think of as static methods in C++). The given
+// metatable argument becomes a metatable for each object of your class. These
+// can be thought of as member functions or methods.
+//
+// You may also supply constructors and destructors for classes that do not
+// have a default constructor or that require special set up or tear down. You
+// may specify NULL as the constructor, which means that you will not be able
+// to call the new function on your class table. You will need to manually push
+// objects from C++. By default, the default constructor is used to create
+// objects and a simple call to delete is used to destroy them.
+//
+// By default LuaWrapper uses the address of C++ object to identify unique
+// objects. In some cases this is not desired, such as in the case of
+// shared_ptrs. Two shared_ptrs may themselves have unique locations in memory
+// but still represent the same object. For cases like that, you may specify an

+// object on to the stack.

+// luaW_register will set table as the new value of the global of the given
+// name. luaW_setfuncs is identical to luaW_register, but it does not set the

+// A set of trivial getter and setter templates. These templates are designed
+// to call trivial getters or setters.
+//
+// There are four forms:
+//  1. Getting or setting a public member variable that is of a primitive type
+//  2. Getting or setting a public member variable that is a pointer to an
+//     object
+//  3. Getting or setting a private member variable that is of a primitive type
+//     through a getter or setter
+//  3. Getting or setting a private member variable that is is a pointer to an
+//     object through a getter or setter
+//
+// The interface to all of them is the same however. In addition to plain
+// getter and setter functions, there is a getset which does both - if an
+// argument is supplied it attempts to set the value, and in either case it
+// returns the value. In your lua table declaration in C++ rather than write
+// individiual wrappers for each getter and setter you may do the following:
+//
+// static luaL_reg Foo_metatable[] =
+// {
+//     { "GetBar", luaU_get<Foo, bool, &Widget::GetBar> },
+//     { "SetBar", luaU_set<Foo, bool, &Widget::SetBar> },
+//     { "Bar", luaU_getset<Foo, bool, &Widget::GetBar, &Widget::SetBar> },
+//     { NULL, NULL }
+// }
+//
+// Getters and setters must have one of the following signatures:
+//    void T::Setter(U value);
+//    void T::Setter(U* value);
+//    void T::Setter(const U& value);
+//    U Getter() const;
+//    U* Getter() const;
+//
+// In this example, the variable Foo::bar is private and so it is accessed
+// through getter and setter functions. If Foo::bar were public, it could be
+// accessed directly, like so:
+//
+// static luaL_reg Foo_metatable[] =
+// {
+//     { "GetBar", luaU_get<Foo, bool, &Widget::bar> },
+//     { "SetBar", luaU_set<Foo, bool, &Widget::bar> },
+//     { "Bar", luaU_getset<Foo, bool, &Widget::bar> },
+// }
+//
+// In a Lua script, you can now use foo:GetBar(), foo:SetBar() and foo:Bar()

+// luaU_func is a special macro that expands into a simple function wrapper.
+// Unlike the getter setters above, you merely need to name the function you
+// would like to wrap.

+// For example,

+// struct Foo
+// {
+//     int DoSomething(int, const char*);
+// };

+// This macro will expand based on the function signature of Foo::DoSomething
+// In this example, it would expand into the following wrapper:
+//
+//     luaU_push(luaW_check<T>(L, 1)->DoSomething(luaU_check<int>(L, 2), luaU_check<const char*>(L, 3)));
+//     return 1;

+// additional macro has been provided, luaU_funcsig, which takes the entire
+// function signature. The arguments to the macro reflect the order they would
+// appear in the function signature: return type, type name, function name, and
+// finally a list of all the argument types. For example:

+// struct Foo
