This patch imports the implementation of haload, a lightweight, multi-threaded traffic generator designed to benchmark HTTP infrastructures under heavy loads. Built onto HAProxy's highly scalable architecture, it natively supports HTTP/1, HTTP/2, and HTTP/3 (QUIC). It uses the previously exposed initialization functions, the no-listener mode, the lightweight hbuf API, and the specialized hldstream object types to dynamically derive and generate its configuration in memory from basic command-line inputs. By leveraging HAProxy's internal HTX (Internal HTTP Native Representation) format, haload abstractly manipulates HTTP elements independently of the wire protocol. This abstraction allows it to generate unified requests and process responses seamlessly across HTTP/1.1, HTTP/2, or HTTP/3 without duplicating the payload handling logic for each version. - Makefile: Introduce the 'haload' compilation target and define HALOAD_OBJS. - src/haload.c, include/haproxy/haload.h: Add user and stream task scheduling handlers, HTX-driven traffic orchestration mechanisms, and terminal benchmarking statistical summary rendering. - src/haload_init.c: Implement program arguments parsing, fileless HAProxy memory configuration generation, and target URL allocations. - src/stconn.c: Wire up sc_attach_mux() to properly allocate the specific tasklet context when dealing with a haload stream. - doc/haload.txt: Add detailed documentation covering compilation, flags, and usage examples.
