d010397be6 MCOL-1197 Make -c work in cpimport
It turns out -c wasn't actually connected to anything and now with have
BLOB/TEXT it is pretty useful. If -c is set to < 1MB then 1MB is used,
otherwise it will use the selected buffer size.

82c383ac20 MCOL-353 Fix lag at end of cpimport
The end of a cpimport adds a delay which is 1 second multiplied by the
number of PMs. This in-turn is multipled up with the number of
connections/threads causing a long delay when you have several PMs.

The delay is not required as we already have a 20ms delay and we will
re-enter the recv() if there is no data and we are still connected.

ffcfc41563 MCOL-507 Further ExeMgr performance improvements
This does the following:

* Switch resource manager to a singleton which reduces the amount of
times the XML data is scanned and objects allocated.
* Make the I_S tables use the FE implementation of the system catalog
* Make the I_S.columnstore_columns table use the RID list cache
* Make the extentmap pre-allocate a vector instead of many small allocs

d551b7d6e0 MCOL-298 Fix saturated date/datetime handling
Saturated DML updates would be set to NULL as were saturated cpimport
values. This sets them to the zero date/datetime value.
