MINOR: http_htx: Add functions to manipulate HTX messages in http_htx.c This file will host all functions to manipulate HTTP messages using the HTX representation. Functions in this file will be able to be called from anywhere and are mainly related to the HTTP semantics.

MEDIUM: proto_htx: Convert all HTTP error messages into HTX During startup, after the configuration parsing, all HTTP error messages (errorloc, errorfile or default messages) are converted into HTX messages and stored in dedicated buffers. We use it to return errors in the HTX analyzers instead of using ugly OOB blocks.

extern struct buffer htx_err_chunks[HTTP_ERR_SIZE];
MEDIUM: htx: Don't rely on h1_sl anymore except during H1 header parsing Instead, we now use the htx_sl coming from the HTX message. It avoids to have too H1 specific code in version-agnostic parts. Of course, the concept of the start-line is higly influenced by the H1, but the structure htx_sl can be adapted, if necessary. And many things depend on a start-line during HTTP analyzis. Using the structure htx_sl also avoid boring conversions between HTX version and H1 version.
