Commit 38686122 changed the function to not give a WARNING, but neglected the comment that says it does.

gporca has a set of banned API calls which needs to be allowed with the ALLOW_xxx macro in order for gpopt to compile. But it should be the library caller(GPDB/Orca)'s resposibility to take care of the function call. see discussions on greenplum-db/gpdb#1136 and https://groups.google.com/a/greenplum.org/forum/#!topic/gpdb-dev/Mcw6JPav6h4

- In ORCA, due to the way exception handled previously we do warning first and then later print error referring that message. In this commit, we enhanced the exception handling so we just print a single error message. - Also, we removed 'PQO unable to generate a plan' or 'Aborting PQO plan generation' message and make the error message as close as the planner. - Updated error message with filename and line number from where the exception is raised.

libgpos has a set of banned API calls which needs to be allowed with the ALLOW_xxx macro in order for gpopt to compile (and thus run). The changes to ereport() brought a need for allowing abort() since it now invokes abort when building with --enable-cassert. This is a temporary fix awaiting the removal of the banning of function calls entirely. Pushed even though the CI pipeline failed to provide a clean run (for seeminly unrelated reasons) due to the absence of this blocking other efforts.

* Fixing DXL Translator bug where we lose canSetTag during Query object mutation and the translator ends up using wrong canSetTag. * Adding ICG test for verifying the the ORCA translator uses correct canSetTag.

* Preventing multiple ResLockPortal calls for the same portal when running multiple queries via PortalRunMulti by correctly populating canSetTag in PlannedStmt from Query object during DXL to PlannedStmt translation. * ICG tests for checking if ORCA correctly populates canSetTag.

This GUC will be used to control the MEMO size as well as optimization time for large IN list or large array comparison expressions. Only the Array with less number of elements than the GUC will be expanded and participate in constraint derivation. Trade-off of using this GUC is loss of potential benefits from the constraint derivation (e.g. conflict detection, partition elimination) with shorter optimization time and less memory utilization.

`set optimizer_join_arity_for_associativity_commutativity=7` will hint at the optimizer to stop exploring join associativity and join commutativity transformations when an n-ary join operator has more than 7 children during optimization, pruning quite a bit of the search space.

Renaming optimizer_release_mdcache to a more intuitive name: optimizer_metadata_caching. Before this commit, we were caching metadata in optimizer side by setting optimizer_release_mdcache = OFF. Now, we cache metadata in optimizer side by setting optimizer_metadata_caching=ON.

ORCA uses its own metadata cache to store information about relations, operators etc. Currently, we always reset the cache when planning a query, unless the optimizer_release_mdcache GUC is turned off, which is slow. To make it safe to turn optimizer_release_mdcache off, use the catalog cache invalidation mechanism to still reset the cache when there are changes to the catalogs that affect the metadata cache. The ORCA-facing interface of this is the same as in the previous attempt: A function that returns true/false indicating whether there has been any catalog changes whatsoever since last call.

This reverts commit 6c31a3b4. Per discussion, we will implement the same functionality in a simpler way.

Added a generation-based Metadata Versioning mechanism which will be used by ORCA to cache and invalidate catalog data in its Metadata Cache. Versioning is disabled by default at this point, until the Metadata Cache eviction policy is completed.

This commit eliminates the global new/delete overrides that were causing compatibility problems (the Allocators.(h/cpp/inl) files have been completely removed). The GPOS `New()` macro is retained and works the same way, but has been renamed `GPOS_NEW()` to avoid confusion and possible name collisions. `GPOS_NEW()` works only for allocating singleton objects. For allocating arrays, `GPOS_NEW_ARRAY()` is provided. Because we no longer override the global delete, objects/arrays allocated by `GPOS_NEW()` and `GPOS_NEW_ARRAY()` must now be deleted by the new functions `GPOS_DELETE()` and `GPOS_DELETE_ARRAY()` respectively. All code in GPOS has been retrofitted for these changes, but Orca and other code that depends on GPOS should also be changed. Note that `GPOS_NEW()` and `GPOS_NEW_ARRAY()` should both be exception-safe and not leak memory when a constructor throws. Closes #166
