Report connection timeout as separate event (#1171 )

Fix #1172 (#1173 )
This change is based on RFC7230, § 3.5 'Message Parsing Robustness': "Although the line terminator for the start-line and header fields is the sequence CRLF, a recipient MAY recognize a single LF as a line terminator and ignore any preceding CR."

+It's extremely easy to setup. Just include the **httplib.h** file in your code!

-Server Example
--------------
+NOTE: This is a multi-threaded 'blocking' HTTP library. If you are looking for a 'non-blocking' library, this is not the one that you want.
+
+Simple examples
+---------------
+
+#### Server
+
+```c++
+#define CPPHTTPLIB_OPENSSL_SUPPORT
+#include "path/to/httplib.h"
+
+// HTTP
+httplib::Server svr;
+
+// HTTPS
+httplib::SSLServer svr;
+
+svr.Get("/hi", [](const httplib::Request &, httplib::Response &res) {
+  res.set_content("Hello World!", "text/plain");
+});
+
+svr.listen("0.0.0.0", 8080);
+```
+
+#### Client
+
+```c++
+#define CPPHTTPLIB_OPENSSL_SUPPORT
+#include "path/to/httplib.h"
+
+// HTTP
+httplib::Client cli("http://cpp-httplib-server.yhirose.repl.co");
+
+// HTTPS
+httplib::Client cli("https://cpp-httplib-server.yhirose.repl.co");
+
+auto res = cli.Get("/hi");
+res->status;
+res->body;
+```
+
+### Try out the examples on Repl.it!
+
+1. Run server at https://repl.it/@yhirose/cpp-httplib-server
+2. Run client at https://repl.it/@yhirose/cpp-httplib-client
+
+SSL Support
+-----------
+
+SSL support is available with `CPPHTTPLIB_OPENSSL_SUPPORT`. `libssl` and `libcrypto` should be linked.
+
+NOTE: cpp-httplib currently supports only version 1.1.1.
+
+```c++
+#define CPPHTTPLIB_OPENSSL_SUPPORT
+#include "path/to/httplib.h"
+
+// Server
+httplib::SSLServer svr("./cert.pem", "./key.pem");
+
+// Client
+httplib::Client cli("https://localhost:1234"); // scheme + host
+httplib::SSLClient cli("localhost:1234"); // host
+
+// Use your CA bundle
+cli.set_ca_cert_path("./ca-bundle.crt");
+
+// Disable cert verification
+cli.enable_server_certificate_verification(false);
+```
+
+Note: When using SSL, it seems impossible to avoid SIGPIPE in all cases, since on some operating systems, SIGPIPE can only be suppressed on a per-message basis, but there is no way to make the OpenSSL library do so for its internal communications. If your program needs to avoid being terminated on SIGPIPE, the only fully general way might be to set up a signal handler for SIGPIPE to handle or ignore it yourself.

+This script splits httplib.h into .h and .cc parts.
+
+optional arguments:
+  -h, --help            show this help message and exit
+  -e EXTENSION, --extension EXTENSION
+                        extension of the implementation file (default: cc)
+  -o OUT, --out OUT     where to write the files (default: out)
+
+$ ./split.py
+Wrote out/httplib.h and out/httplib.cc
 ```

 NOTE
 ----

+### g++
+
 g++ 4.8 and below cannot build this library since `<regex>` in the versions are [broken](https://stackoverflow.com/questions/12530406/is-gcc-4-8-or-earlier-buggy-about-regular-expressions).

+### Windows
+
+Include `httplib.h` before `Windows.h` or include `Windows.h` by defining `WIN32_LEAN_AND_MEAN` beforehand.
+
+```cpp
+#include <httplib.h>
+#include <Windows.h>
+```
+
+```cpp
+#define WIN32_LEAN_AND_MEAN
+#include <Windows.h>
+#include <httplib.h>
+```
+
+Note: cpp-httplib officially supports only the latest Visual Studio. It might work with former versions of Visual Studio, but I can no longer verify it. Pull requests are always welcome for the older versions of Visual Studio unless they break the C++11 conformance.
+
+Note: Windows 8 or lower and Cygwin on Windows are not supported.
