Add SSL-related TLV types PP2_SUBTYPE_SSL_CIPHER,
PP2_SUBTYPE_SSL_SIG_ALG and PP2_SUBTYPE_SSL_KEY_ALG. Rename
PP2_TYPE_CHECKSUM to PP2_TYPE_CRC32C to make it easier to add checksums
using other algorithms. Clarified encoding of the string fields.
Renamed ASCII to US-ASCII as recommended by
https://www.iana.org/assignments/character-sets/character-sets.xhtml.
Add the CRC32c checksum TLV PP2_TYPE_CHECKSUM. Reserve TLV type ranges
CUSTOM, EXPERIMENT and FUTURE. Clarify that only UNSPEC protocol byte is
mandatory to implement on the receiver.

rename the field <ver_cmd> to avoid any ambiguity on the usage.

This commit modifies the PROXY protocol V2 specification to support headers
longer than 255 bytes allowing for optional extensions. It implements the
PROXY protocol V2 which is a binary representation of V1. This will make
parsing more efficient for clients who will know in advance exactly how
many bytes to read. Also, it defines and implements some optional PROXY
protocol V2 extensions to send information about downstream SSL/TLS
connections. Support for PROXY protocol V1 remains unchanged.
The doc updates covers the following points :
- description of protocol version 2
- discourage emission of UNKNOWN and encourage it acceptance
- clarify that each header must fit in an MSS and be sent at once
- provide an example of receiver code that explains how to use MSG_PEEK.
