Fixed bug report template.

Added bug report template.

Modernize CMakeLists.txt

WIth this I'm trying to fix some of the issues pointed out in #827.

Changes:

Use add_compile_options() instead of modifying CMAKE_CXX_FLAGS.

Use -Og instead of -O0
(from https://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html :
[-Og] is a better choice than -O0 for producing debuggable code because
some compiler passes that collect debug information are disabled at -O0)

Fix LTO check (previously it would fail because it checked only
CMAKE_CXX_FLAGS. This didn't work when properly enabling LTO
through CMAKE_INTERPROCEDURAL_OPTIMIZATION).
I'm not sure if I modified it correctly since I don't really understand
what that check is trying to do in the first place.

Check for Clang or GCC when applying compiler specific flags.

This changes require CMake 3.9 or higher, but I don't think this will
cause any issues.

* - Adding Router::addDisconnectHandler to handle client disconnections.
- Adding code to call handlers on client disconnection

* - Adding test case for router addDisconnectHandler and associated functionality.

* Changing to 2-space indentation and other formating changes to conform to LLVM style

* More format changes

* Fix issue #842

* Add one more dot

* Follow review suggestions

* clang format + small change

Code simplification in RequestParser usage

Repo has been moved to a new organization. Update the build status URL to reflect for organization change in travis-ci

Fix several unnecessary copies of objects

Fix #840

* Adding an incrementing peer ID for easier connection identification on peer disconnect

* Removing the private override of onDisconnection in http::Handler

* Adding unit test for onDisconnection

* - Exposing a peer handle from the ResponseWriter
- Making disconnection test a bit more deterministic; there appears to be a race condition between server.shutdown() returning and the onDisconnection() callback succeeding.
- Adding Active Connections info in test case to demonstrate usage.

* Reducing verbosity of test output

* Fixing getID vs getId call, removing block comment around other tests

fix chunked transfer decoding

Don't build and install pistache_shared if the standard cmake
BUILD_SHARED_LIBS is set to OFF

- usage of complete body_.size() seems is wrong (only valid if there is one chunk?)
- use separate var to count already received bytes of chunk

* fix issue-193

The client implementation isn't compliant with HTTP 1.1 standard, to be
specific, it doesn't honor the "Connection: close" response header. As a
result, whenever a new request is sent, a new tcp connection is opened
to the server and is never closed (unless the server close it).

The best place to close the connection is in Connection::OnDone() method,
however, that method is provided too early, in the Connection::asyncPerform()
method, where the Http::Response object is not yet available. It's also
incorrect to blindly close the connection in OnDone() method, as there might
be more data from server.

This commit explicitly closes all opened connections on Client::shutdown(),
to guarantee all network resources are recycled on that call.

It's impossible to write any unit test case verify it, the connection pool
is invisible to Client users. It passed manual tests on crafted scenarios.

To verify this, start a Pistache server from the examples, then use the Client
library to send some requests to the server, and don't terminate client side
program. Use "netstat -an | grep <server_port>" to see if there are remaining
connections in ESTABLISHED state after client.shutdown() is called.

* fix formatting issue

Revert "Use a std::shared_ptr<std::string> instead of std::string for the body_ member variable in Pistache::Http::Message (#814)" (#816)

This reverts commit a09290ee.

Use a std::shared_ptr<std::string> instead of std::string for the body_ member variable in Pistache::Http::Message (#814)

As a Pistache::Http::Message object is copied several times during the handling of a request this leads to a significant reduction in memory usage when uploading files through a http post.

This will fix the detection of atomic:

-- Performing Test HAVE_CXX_ATOMICS64_WITHOUT_LIB
-- Performing Test HAVE_CXX_ATOMICS64_WITHOUT_LIB - Failed
-- Looking for __atomic_load_8 in atomic
-- Looking for __atomic_load_8 in atomic - not found
CMake Error at CMakeModules/CheckAtomic.cmake:76 (message):
  Host compiler appears to require libatomic for 64-bit operations, but
  cannot find it.
Call Stack (most recent call first):

Indeed if C language is not enabled, the test will be run with the C++
compiler resulting in the following error:
