The master process does not need all the keywords of the cli, add 2
flags to chose which keyword to use.
It might be useful to activate some of them in a debug mode later...
In order to use arbitrary data in the CLI (multiple lines or group of words
that must be considered as a whole, for example), it is now possible to add a
payload to the commands. To do so, the first line needs to end with a special
pattern: <<\n. Everything that follows will be left untouched by the CLI parser
and will be passed to the commands parsers.
Per-command support will need to be added to take advantage of this
feature.

Adds cli commands to change at runtime whether informational messages
are prepended with severity level or not, with support for numeric and
worded severity in line with syslog severity level.
Adds stats socket config keyword severity-output to set default behavior
per socket on startup.
This way we don't have any more state specific to a given yieldable
command. The other commands should be easier to move as they only
involve a parser.
It really belongs to proto_http.c since it's a dump for HTTP request
and response errors. Note that it's possible that some parts do not
need to be exported anymore since it really is the only place where
errors are manipulated.
The table dump code was a horrible mess, with common parts interleaved
all the way to deal with the various actions (set/clear/show). A few
error messages were still incorrect, as the "set" operation did not
update them so they would still report "unknown action" (now fixed).
The action was now passed as a private argument to the CLI keyword
which itself is copied into the appctx private field. It's just an
int cast to a pointer.
Some minor issues were noticed while doing this, for example when dumping
an entry by key, if the key doesn't exist, nothing is printed, not even
the table's header. It's unclear whether this was intentional but it
doesn't really match what is done for data-based dumps. It was left
unchanged for now so that a later fix can be backported if needed.
Enum entries STAT_CLI_O_TAB, STAT_CLI_O_CLR and STAT_CLI_O_SET were
removed.
Move the "show info" command to stats.c using the CLI keyword API
to register it on the CLI. The stats_dump_info_to_buffer() function
is now static again. Note, we don't need proto_ssl anymore in cli.c.
Move the "show stat" command to stats.c using the CLI keyword API
to register it on the CLI. The stats_dump_stat_to_buffer() function
is now static again.
Move 'show sess' CLI functions to stream.c and use the cli keyword API
to register it on the CLI.
[wt: the choice of stream vs session makes sense because since 1.6 these
really are streams that we're dumping and not sessions anymore]
Move map and acl CLI functions to map.c and use the cli keyword API to
register actions on the CLI. Then remove the now unused individual
"add" and "del" keywords.
proto/dumpstats.h has been split in 4 files:
* proto/cli.h contains protypes for the CLI
* proto/stats.h contains prototypes for the stats
* types/cli.h contains definition for the CLI
* types/stats.h contains definition for the stats
