Formats an HTTP 1.1 message header.

Formats an message header in HTTP 1.x format, using HTTP version 1.1.

Parameters

m	message to format/serialize
lenp	location to write the length of the formatted message in bytes [OUT]
proxied	whether the message is meant for sending to a proxy rather than an origin (only relevant for requests)
chunked	whether to append a chunked transfer encoding header line

Returns

A heap-allocated nul-terminated string or *lenp bytes, or NULL on error
