FEATURE - support for reading directly from zip and other archives

Similar to the way that we support reading from git repositories, and
using the same hooks and filename format.

Uses libarchive.

Fix internal error on complex nested field selection

In some circumstances it was possible to get the following error:
Attempting to lookup field <name> in a dataset which has no active element.
This is preventing another option being enabled that would solve some
problems with conditional evaluation of expressions.

The root cause is the handling of no_select.  A no_select should have a
newAtom attribute associated with it if it is selecting a field from a
new row.  So a[1].b.c is represented as
  select(select(a[1],b,new),c)

Some places were incorrectly checking if the current select had an
associated new attribute instead of checking if the root select had
one.

no_select(no_selectnth) now always has a newAttribute associated with it.
This simplifies and optimizes the processing of unnormalized trees.

This also contains a fix for hqliproj projecting a datarow, and better
expansion of (a.b.c.d within transforms)

SelfJoin object leak, cause error if spilled

SelfJoin was leaking the lhs input stream, as a result, if a local selfjoin
had spilt whilst sorting, the spill files remained opened and an error
ensued.

Restructure child dataset flags so they are more useful

This change only modifies the values for the different flags.
It means that the values can be masked to determine subsets of the
information (e.g., does it refer to LEFT/RIGHT), does it have a single
input dataset.

gh-2187 hpcc-init fails to stop thor on Ubuntu 12.04

There is a regression in the killall program in the current Ubuntu 12.04
distro's repositories, which prevents killall from working as advertised
on longer executable names.

See https://bugs.launchpad.net/ubuntu/+source/psmisc/+bug/970638

Testing suggests that providing a full pathname that the executable was launched
with, as opposed to just the tail name, will work around the issue.

Without this workaround, thor cannot be properly stopped on Ubuntu 12.04 systems.

Fixes gh-2187.
