Alexander Barton 84a599ece4 Enable WHOIS to display information about IRC Services
This patch introduces the new numeric 310(RPL_WHOISSERVICE) and enables
WHOIS to display information about IRC services. This numeric is used
for this purpose by InspIRCd, for example -- but as usual, other numerics
are in use, too, like 613 in UltimateIRCd ...

Please note that neither the Operator (+o) not the "bot status" (+B)
of an IRC service id displayed in the output.

Change suggested by Federico G. Schwindt <fgsch@lodoss.net>, Thanks.

Alexander Barton c891b5f250 autogen.sh: Check for autoconf/automake wrapper scripts
For example OpenBSD uses a "autoconf" and "automake" wrapper script which
tells the user to set AUTOCONF_VERSION and AUTOMAKE_VERSION environment
variables. This patch enhances autogen.sh to not detect these wrapper
scripts as regular autoconf/automake commands but to set the required
environment variables after detecting the real "command-X.Y" commands.

Tested on OpenBSD 5.1.

Alexander Barton 419ff38a07 autogen.sh: Don't use "egrep -o", use "sed"
"egrep -o" isn't portable and not available on OpenBSD, for example. So
let's use sed instead to get the automake version. The expression used
now is less specific but should work as well ...

Alexander Barton 8d8201502f IRC_WHO_Channel(): Use strlcpy() instead of strcpy()
This fixes the following warning, at least on OpenBSD 4.8:

 irc-info.o(.text+0x2427): In function `IRC_WHO':
 src/ngircd/irc-info.c:896: warning: strcpy() is almost always misused,

Alexander Barton d38d153f51 Streamline punctuation of log messages
Make sure that all log messages end with a correct punctuation mark.

The rules for formatting log messages are:

 1. Add punctuation marks to all messages passed to the actual logging
    functions like Log() and LogDebug().
 2. Don't add any punctuation marks to messages that are stored in
    variables for later use or are passed over the network.
 3. IP addresses, DNS host names and IRC server names should be quoted.
 4. Messages originating in the network should be quoted (at least if
    they are "untrusted" or variable).

Most probably this patch doesn't fix all mistakes, but it should be a
good starting point ...

Alexander Barton fd260404ca configure: "netinet/in_systm.h" is optional
The header file "netinet/in_systm.h" already is optional in ngIRCd, so
don't require it in the configure script. Now ngIRCd can be built on
Minix 3 again :-)

DNS a551942635 contrib/Debian/rules: Do no compress Commands.txt

Alexander Barton 3d49e8ac84 ngircd.service: Use "forking" service type
Don't run ngIRCd in forground mode but let it daemonize itself. This
enhances the log output of "systemctl status ngircd.service", because
now ngIRCd doesn't print out its PID and timestamp on each log message
which is redundant: it becomes logged by systemd/journald already.

Alexander Barton 508ca3044d Return better "Connection not registered as server link" errors
Now ngIRCd returns a more specific error message for numeric
ERR_NOTREGISTERED(451) when a regular user tries to use a command that
isn't allowed for users but for servers: ERR_NOTREGISTEREDSERVER(451).

Alexander Barton d8f2964710 MODE: don't report error on "more modes than parameters"
Don't report ERR_NEEDMOREPARAMS(461) when a MDOE command with more modes
than nicknames is handled, as well as for channel limit and key changes
without specifying the limit or key parameters.

This is how a lot (all?) other IRC servers behave, including ircd2.11,
InspIRCd, and ircd-seven. And because of clients (tested with Textual and
mIRC) sending bogus MODE commands like "MODE -ooo nick", end-users got the
expected result as well as correct but misleading error messages ...

If ngIRCd is compiled using "strict mode", these errors are still reported.

Alexander Barton ab00997698 Correctly detect when SSL subsystem must be initialized
This patch introduces the new function Conf_SSLInUse() to check when the
current server configuration requires the SSL subsystem to be initialized
and accounts incoming as well as outgoing connections -- so this fixes
commit bb20aeb9 ("Initialize SSL when needed only, and disable SSL on
errors") which only handled the inbound case  ...

Alexander Barton 289a26e9e4 Implement Help() function parsing and returning the help text
This function parses the already read in help text and sends the requested
portions to the user. Parsing is done as following when a user user
issues a "HELP <cmd>" command:

 1. Search the file for a line "- <cmd>",
 2. Output all subsequent lines that start with a TAB (ASCII 9) character
    to the client using NOTICE commands, treat lines containing a single "."
    after the TAB as empty lines.
 3. Break at the first line not starting with a TAB character.

This format allows to have information to each command stored in this file
which will not be sent to an IRC user requesting help which enables us to
have additional annotations stored here which further describe the origin,
implementation details, or limits of the specific command.

A special "Intro" block is returned to the user when the HELP command is
used without a command name.

Alexander Barton 20ddffca0d Mode setting: only check channel user modes when on channel
Only check the channel user modes of the initiator if he is joined to
this channel and not an IRC operator enforcing modes (which requires
the configuration option "OperCanUseMode" to be enabled), because trying
to check channel user modes of a non-member results in this assertion:

 Assertion failed: (cl2chan != NULL), function Channel_UserModes,
  file channel.c, line 742.

This closes bug #147, thanks to James Kirwill <james.kirwill@bk.ru>
for tracking this down!

Alexander Barton 35e2dcff88 Rework cloaked hostname handling, implement "METADATA cloakhost"
Now ngIRCd uses two fields internally, one to store the "real" hostname
and one to save the "cloaked" hostname. And both fields can be set
independently using the "METADATA host" and "METADATA cloakhost" commands.

This allows "foreign servers" (aka "IRC services") to alter the real and
cloaked hostnames of clients without problems, even when the user itself
issues additional "MODE +x" and "MODE -x" commands.
