nanonext 1.10.0

New Features

• Adds device_aio() to run an asynchronous device: a zero-copy forwarder that relays raw messages between two Sockets, for building brokers and proxies.

Updates

• ncurl(), ncurl_aio() and ncurl_session() again accept a named list (as well as a named character vector) for the headers argument.
• An error signalled by an HTTP server request handler, which maps to a 500 response, no longer additionally prints the error to the console.
• Fixes receiving using mode = 'character' so that a received character vector is exactly that which was sent, preserving empty strings in all positions (previously trailing empty strings were dropped, and elements could be lost when leading empty strings were present).
• Fixes potential message corruption when built against a system 'libnng', regression in 1.9.0.
• Fixes a 'Resource busy' error triggered by re-using a 'tlsConfig' object for more than one connection.
• Updates the bundled NNG version to 1.12.0, and the bundled Mbed TLS sources to remove unused modules.
• Increases the minimum supported system libnng version to >= 1.12.0, and 'libmbedtls' version to >= 3.0.
• Removes the build-time dependency on 'cmake'. Compiling the bundled NNG and Mbed TLS sources now only require a C compiler.
