Frédéric Lécaille 3097be92f1 MEDIUM: quic: Dynamic allocations of QUIC TLS encryption levels
Replace ->els static array of encryption levels by 4 pointers into the QUIC
connection object, quic_conn struct.
    ->iel denotes the Initial encryption level,
    ->eel the Early-Data encryption level,
    ->hel the Handshaske encryption level and
    ->ael the Application Data encryption level.

Add ->qel_list to this structure to list the encryption levels after having been
allocated. Modify consequently the encryption level object itself (quic_enc_level
struct) so that it might be added to ->qel_list QUIC connection list of
encryption levels.

Implement qc_enc_level_alloc() to initialize the value of a pointer to an encryption
level object. It is used to initialized the pointer newly added to the quic_conn
structure. It also takes a packet number space pointer address as argument to
initialize it if not already initialized.

Modify quic_tls_ctx_reset() to call it from quic_conn_enc_level_init() which is
called by qc_enc_level_alloc() to allocate an encryption level object.

Implement 2 new helper functions:
  - ssl_to_qel_addr() to match and pointer address to a quic_encryption level
    attached to a quic_conn object with a TLS encryption level enum value;
  - qc_quic_enc_level() to match a pointer to a quic_encryption level attached
    to a quic_conn object with an internal encryption level enum value.
This functions are useful to be called from ->set_encryption_secrets() and
->add_handshake_data() TLS stack called which takes a TLS encryption enum
as argument (enum ssl_encryption_level_t).

Replace all the use of the qc->els[] array element values by one of the newly
added ->[ieha]el quic_conn struct member values.

The HAProxy documentation has been split into a number of different files for
ease of use.

Please refer to the following files depending on what you're looking for :

  - INSTALL for instructions on how to build and install HAProxy
  - BRANCHES to understand the project's life cycle and what version to use
  - LICENSE for the project's license
  - CONTRIBUTING for the process to follow to submit contributions

The more detailed documentation is located into the doc/ directory :

  - doc/intro.txt for a quick introduction on HAProxy
  - doc/configuration.txt for the configuration's reference manual
  - doc/lua.txt for the Lua's reference manual
  - doc/SPOE.txt for how to use the SPOE engine
  - doc/network-namespaces.txt for how to use network namespaces under Linux
  - doc/management.txt for the management guide
  - doc/regression-testing.txt for how to use the regression testing suite
  - doc/peers.txt for the peers protocol reference
  - doc/coding-style.txt for how to adopt HAProxy's coding style
  - doc/internals for developer-specific documentation (not all up to date)
