* Adds support for terminal and partial cancellation to async_run.
* Makes basic_connection::cancel use per-operation cancellation under the hood.
* Fixes a number of race conditions during cancellation which could cause the cancellation to be ignored. This could happen if the cancellation is delivered while an async handler is pending execution.
* Deprecates operation::{resolve, connect, ssl_handshake, reconnection, health_check}, in favor of operation::run. Calling basic_connection::cancel with these values (excepting reconnection) is now equivalent to using operation::run.
* Fixes a problem in the health checker that caused ping timeouts to be reported as cancellations.
* Sanitizes how the parallel group computes its final error code.
* Simplifies the reader, writer and health checker to not care about connection cancellation. This is now the responsibility of the parallel group.
* Removes an unnecessary setup_cancellation action in the reader FSM.
* Adds documentation regarding per-operation cancellation to async_receive.
* Adds additional health checker tests.
* Adds async_run per-operation cancellation tests.
* Adds reader FSM cancellation tests.
* Makes test_conn_exec_retry tests more resilient.
* Removes leftovers in the UNIX and TLS reconnection tests. These were required due to race conditions that have already been fixed.

Updates multiplexer to make requests complete with error_code() rather than error_code(0)
Integration tests now use io_context::run_for to run with a timeout and avoid deadlocks
Tests now use concrete lambdas where generic ones are not required
Tests now use BOOST_TEST with operator== to print values on error
Tests now use anonymous namespaces to detect dead code
Adds run_coroutine_test and removed start from common.hpp
Updates test_reconnect to perform relevant checks
Refactors how test_issue_50 launches its coroutines
Groups tests in CMake as unit or integration
Updates Jamfile tests to contain all unit tests and only unit tests

Before these changes the request had to be marked as written in order to
interpret incoming responses as belonging to that request. On fast
networks however, like on localhost and underload the responses might
arrive before the write operation completed.
