Issue

This issue is advance notice that compilation fails with the upcoming Boost 1.89.0 (planned release Aug 13).

The Boost changes that impact OSRM backend include:

1. boostorg/asio@cb99678 - boost::asio::deadline_timer is no longer available via boost/asio.hpp. For now, this is available via the boost/asio/deadline_timer.hpp¹ but it may be removed in future release given deprecated status.

2. boostorg/geometry@38455d0 - boost/geometry/multi/ headers are removed. Specifically for multi_linestring, it has been available in boost/geometry/geometries/geometries.hpp or boost/geometry/geometries/multi_linestring.hpp since 1.56.0²

Steps to reproduce

Please provide the steps required to reproduce your problem.

• osrm-backend version being used - v6.0.0
• OSM extract that was processed - N/A
• Processing commands (e.g. CH vs MLD processing) - N/A
• Server queries - N/A

Can be reproduced by building with Boost 1.89.0.beta1 or with Boost 1.89.0 (tomorrow). Haven't checked but sometimes Boost has macros to hide deprecated code.
