#2600 Firs phase SQL Join support
Support single join (inner or outer)
Join clause turns off index file use
EclEngine utilizes maps for quick lookup of corresponding table->index,
 and source dataset name
ECL code is more centralized, support for multiple files enabled.
HPCCPrepStatement - now contains cache for multiple index files.
HPCCResultSet - contains structure with all available columns (from all tables in query)
              - index turned off for join queries (temporary)
All expression fragments now contain parent table, and field name.

Improvements to the eclcc regression script

* Generate a make file that can be rerun without rerunning the script

* Allow extra flags to be specified

* Add a make target to rebuild each file.  Use make file.run -B to
  rerun that particular test

Split BCD tests, init with zero
Use ASSERT(check(cond, fmt, args))

check() logs the error and return the condition, so that
ASSERT can fail the test (or not). Failing power tests,
but logging all possible information beforehand (as
previously).
Comments, better assert
Rename TempDecimal to Decimal
Expect rounding of the last digit
Remove fixmissing flag

This flag controlling an internal process to the
superfile, arguably on the wrong place, was being
passed around many methods and exposed to the
directory and even FileServices.

The assumption that it should fail on some cases
and only warn on others is wrong. This method
should not attempt to bypass problems in the
DFS, as it'll only silently propagate the original
problem.

The behaviour now is to throw at the slightest
sign of trouble, only warning when the file is
foreign (external Dali) or the number of subfiles
is different. The latter might be an error, too,
but I'll leave it for later consideration.
Simplify loadSubFiles

Avoiding the use of an additional array to hold files,
using the iterator directly. The first pass will check
for consistency (number of sub-files and final index).
The second pass will lock the files or fail on error.
ForEach first redundant
