Adds from/tags/desc/extdesc properties, even when absent or blank.

When parsing a file object, set the from, desc, tags and cost properties only if they already have been set or the new values is non-blank/0.

So just always assume that no "user" directory has been configured. At least for now while I ponder whether this is a feature worth restoring and if so, how.

Previously, these both used gettimeofday() which is both expensive
to call, and not monotonic.

This fixes system.clock_ticks in JS and various internal bits. for
when the UTC wall clock jumps.

While we're here, fix the documention of system.clock_ticks

For Nelgin, to reduce log spam.

- Add a unique number to event names for each request
  Prevents responses from being acepted by multiple queries
- Don't set Socket.dnsObject for synchronous lookups
- OPcode of 2 is used for status replies (ie: NXDOMAIN)
- Be more careful construct result array in request()

warning: format not a string literal and no format arguments

Also, have handle_response() return errors.

Caught by CID 331001

The use of SAFECAT() with a typecast to a pointer is not going to work as expected. This change broke line-based telnet-gateway functionality (unconfirmed, but pretty obvious).

Likely the cause of the crash that killed cvs.synchro.net last night

If brand_link specified in modopts, use that as href for navbar-brand link (BBS name at top left); for CG.

Specifically, have errors mean the fd is "ready".

Also, fix some extra revent clearing and a spy socket issue while
we're looking at this code.

Should fix issues with CGI scripts that close stdin/stdout but do
not terminate, and maybe deal with some other corner cases at the
same time.

Tabs are the shit.

For easier use of the auto-generated echo-tags in JS.
And a helper function sub_area_tag(), now used in SCFG too.

First IRCd 1.9 changes

See merge request !125

Previously, timed or polled callbacks were required to keep the
event loop running.

Update array.js formatting

See merge request !120

This should allow callbacks to not interfere between (say) shells
and doors.

Like the -d option for ADDFILES.

For Al (TRMB)

I haven't added a clearImmediate() because there's currently no way
of manipulating the run queue, and I can't come up with a reason
someone would actually need it.

Was terribly broken.

Also, check that the opcode and response flag are correct when
parsing responses.

When handling a resolve call, ensure no errors occured.
