CLEANUP: dynbuf: remove the unused b_alloc_fast() function
It is never used anymore since 1.7 where it was used by b_alloc_margin() then replaced by direct calls to the pools function, and it maintains a dependency on the exposed pools functions. It's time to get rid of it, as it's not even certain it still works. |

CLEANUP: dynbuf: remove b_alloc_margin()
It's not used anymore, let's completely remove it before anyone uses it again by accident. |

MINOR: dynbuf: make b_alloc() always check if the buffer is allocated
Right now there is a discrepancy beteween b_alloc() and b_allow_margin(): the former forcefully overwrites the target pointer while the latter tests it and returns it as-is if already allocated. As a matter of fact, all callers of b_alloc() either preliminary test the buffer, or assume it's already null. Let's remove this pain and make the function test the buffer's allocation before doing it again, and match call places' expectations. |

DOC: scheduler: add a diagram showing the different queues and their usages
The scheduler has become complex over time and the latest updates were a good opportunity to document it. This diagram shows the time-based wait queue(s), the priority-based run queue(s), and the class-based tasklet queues, trying to emphasize what is local-only and what is shared between threads. The diagram is provided in .fig, .svg, .png, and .pdf. |

DOC: Update the filters guide
The filters guide was totally outdated. Callbacks to filter payload were changed, especially the HTTP one because of the HTX. All the HTTP legacy part is removed. This new guide now reflects the reality. This patch may be backported as far as 2.2. |

DOC: Update the HTX API documentation
Missing functions have been added. And because the EOM block was removed, some parts have been adapted to better explain how the end of the message may be detected. |

MAJOR: htx: Remove the EOM block type and use HTX_FL_EOM instead
The EOM block may be removed. The HTX_FL_EOM flags is enough. Most of time, to know if the end of the message is reached, we just need to have an empty HTX message with HTX_FL_EOM flag set. It may also be detected when the last block of a message with HTX_FL_EOM flag is manipulated. Removing EOM blocks simplifies the HTX message filling. Indeed, there is no more edge problems when the message ends but there is no more space to write the EOM block. However, some part are more tricky. Especially the compression filter or the FCGI mux. The compression filter must finish the compression on the last DATA block. Before it was performed on the EOM block, an extra DATA block with the checksum was added. Now, we must detect the last DATA block to be sure to finish the compression. The FCGI mux on its part must be sure to reserve the space for the empty STDIN record on the last DATA block while this record was inserted on the EOM block. The H2 multiplexer is probably the part that benefits the most from this change. Indeed, it is now fairly easier to known when to set the ES flag. The HTX documentaion has been updated accordingly. |

CLEANUP: fd: finally get rid of fd_done_recv()
fd_done_recv() used to be useful with the FD cache because it used to allow to keep a file descriptor active in the poller without being marked as ready in the cache, saving it from ringing immediately, without incurring any system call. It was a way to make it yield to wait for new events leaving a bit of time for others. The only user left was the connection accepter (listen_accept()). We used to suspect that with the FD cache removal it had become totally useless since changing its readiness or not wouldn't change its status regarding the poller itself, which would be the only one deciding to report it again. Careful tests showed that it indeed has exactly zero effect nowadays, the syscall numbers are exactly the same with and without, including when enabling edge-triggered polling. Given that there's no more API available to manipulate it and that it was directly called as an optimization from listener_accept(), it's about time to remove it. |

MEDIUM: listeners: remove the now unused ZOMBIE state
The zombie state is not used anymore by the listeners, because in the last two cases where it was tested it couldn't match as it was covered by the test on the process mask. Instead now the FD is either in the LISTEN state or the INIT state. This also avoids forcing the listener to be single-dimensional because actually belonging to another process isn't totally exclusive with the other states, which explains some of the difficulties requiring to check the proc_mask and the fd sometimes. So let's get rid of it now not to be tempted to reuse it. The doc on the listeners state was updated. |

DOC: internal: document the init calls
INITCALLs are used a lot in the code now and were not documented, resulting in each user having to grep for functions in other files. This doc is not perfect but aims at improving the situation. It documents what's been available since 1.9 and may be backported there if it helps though it's unlikely to be needed as it's mostly aimed at developers. |

BUG/MINOR: buffers/threads: always clear a buffer's head before releasing it
A small race exists in buffers with "show sess all". This one wants to show some information grabbed from the buffer (especially in HTX mode). But the thread owning this buffer might just be releasing its area, right after a free() or munmap() call, resulting in a head that is not seen as empty yet though the area was released. It may then be dereferenced by "show sess all" causing a crash. Note that in practice it only happens in debug mode with UAF enabled, but it's tricky enough to fix it right now. This should be backported to stable versions which support threads and a store barrier. It's worth noting that by performing the clearing first, b_free() and b_drop() now become two exact equivalent. |

MEDIUM: stream-int: introduce a new state SI_ST_RDY
The main reason for all the trouble we're facing with stream interface error or timeout reports during the connection phase is that we currently can't make the difference between a connection attempt and a validated connection attempt. It is problematic because we tend to switch early to SI_ST_EST but can't always do what we want in this state since it's supposed to be set when we don't need to visit sess_establish() again. This patch introduces a new state betwen SI_ST_CON and SI_ST_EST, which is SI_ST_RDY. It indicates that we've verified that the connection is ready. It's a transient state, like SI_ST_DIS, that cannot persist when leaving process_stream(). For now it is not set, only verified in various tests where SI_ST_CON was used or SI_ST_EST depending on the cases. The stream-int state diagram was minimally updated to reflect the new state, though it is largely obsolete and would need to be seriously updated. |

MEDIUM: streams: Add the ability to retry a request on L7 failure.
When running in HTX mode, if we sent the request, but failed to get the answer, either because the server just closed its socket, we hit a server timeout, or we get a 404, 408, 425, 500, 501, 502, 503 or 504 error, attempt to retry the request, exactly as if we just failed to connect to the server. To do so, add a new backend keyword, "retry-on". It accepts a list of keywords, which can be "none" (never retry), "conn-failure" (we failed to connect, or to do the SSL handshake), "empty-response" (the server closed the connection without answering), "response-timeout" (we timed out while waiting for the server response), or "404", "408", "425", "500", "501", "502", "503" and "504". The default is "conn-failure". |

MINOR: buffers: add a new b_move() function
This function will be used to move parts of a buffer to another place in the same buffer, even if the parts overlap. In order to keep things under reasonable control, it only uses a length and absolute offsets for the source and destination, and doesn't consider head nor data. |

All these calls have in common to consume a single pointer and return void. Doing this removes 26 constructors. The following calls were addressed : - acl_register_keywords - bind_register_keywords - cfg_register_keywords - cli_register_kw - flt_register_keywords - http_req_keywords_register - http_res_keywords_register - protocol_register - register_mux_proto - sample_register_convs - sample_register_fetches - srv_register_keywords - tcp_req_conn_keywords_register - tcp_req_cont_keywords_register - tcp_req_sess_keywords_register - tcp_res_cont_keywords_register - flt_register_keywords |

MINOR: buffers: add b_xfer() to transfer data between buffers
Instead of open-coding buffer-to-buffer transfers using blocks, let's have a dedicated function for this. It also adjusts the buffer counts. |

DOC: buffers: remove obsolete docs about buffers
A number of outdated docs dating 2012 about buffers implementation and management were totally irrelevant to the current code (and even to most 1.8 code as well). These docs have all been removed so that only the up to date documentation remains. |

MAJOR: chunks: replace struct chunk with struct buffer
Now all the code used to manipulate chunks uses a struct buffer instead. The functions are still called "chunk*", and some of them will progressively move to the generic buffer handling code as they are cleaned up. |

MINOR: channel/buffer: replace b_{adv,rew} with c_{adv,rew}
These ones manipulate the output data count which will be specific to the channel soon, so prepare the call points to use the channel only. The b_* functions are now unused and were removed. |
