ICG changes for commit "Add 4 xforms for LOJ index apply on dynamic table
scan"

These transforms existed for non-partition tables, but not for partition
tables.
Authored-by: NChris Hajas <chajas@pivotal.io>

Also, bump ORCA version to 2.61.0

Also bump version to 3.60.0.

This commit corresponds with ORCA commit "Implement Full Merge Join in ORCA".
It also bumps ORCA version to v3.59.0.

This commit includes the following changes to support merge join in
ORCA:
1. Update optimizer_expand_fulljoin guc to use traceflags instead of
disabling the transform.
2. Translator changes for Merge Join.
3. Add IsOpMergeJoinable() and GetMergeJoinOpFamilies() wrappers.
4. Introduces the guc optimizer_enable_mergejoin.

3.58.0 corresponds to commit "Only create PropConstraint hashmap if
necessary"
3.58.1 corresponds to commit "Fix stack-use-after-scope for
`CCacheHashtableAccessor` instantiation"

This commits adds a new GUC that controls the xform:
optimizer_push_group_by_below_setop_threshold.

Also bump ORCA version to 3.49.0

Earlier we didn't bother converting an in list of constants into an ArrayExpr
when then number of elements was larger than array_expansion_threshold.

We still should create an ArrayExpr because it can be useful in deriving stats
on filters even if we are not deriving constraints on it.

Bump ORCA version to v3.47.0

The IMemoryPool interface was removed in ORCA to remove an unnecessary
abstraction layer and avoid costly casting.

Bumps ORCA version to 3.46.0
Authored-by: NChris Hajas <chajas@pivotal.io>

Add exhaustive2 option to optimizer_join_order guc.
The corresponding ORCA PR is
https://github.com/greenplum-db/gporca/pull/467.

The same change will go into 6X_STABLE. In 5X_STABLE, the new guc
option will not be available.

Also bump ORCA version to v3.44.0.

Includes ICG changes for ORCA commit:
'Convert FULL OUTER JOIN to LEFT JOIN when possible'

Also add a few more tests for unions to ICG.

The functionality to send alerts via email (and snmp was removed in
commit 65822b80 but I missed removing
the autoconf check for the libcurl feature required. Since there are
no more consumers, remove the check and feature macro as well.

This corresponds to ORCA commit "Predicate pushdown in part tables with window func"
It includes ICG changes

Compilation with --enable-testutils seems to has been broken long time
as `MaxDynamicLWLock` is no more defined. Given no one complained
seems this is unused config option and code. Hence, instead of fixing
the compilation ripping out this code.

This corresponds to ORCA commit "Use prime number of buckets to avoid
hash collisions"
Authored-by: NChris Hajas <chajas@pivotal.io>

If getversion is not able to determine a version from git then it uses
the version in configure.in (autconf).
configure was generated by running `autoreconf` after modifiying
configure.in.

Also made changes to other areas expliciting mentioning Greenplum
"6.0.0" which should now be "7.0.0".
