Add amcheck extension to contrib. This is the beginning of a collection of SQL-callable functions to verify the integrity of data files. For now it only contains code to verify B-Tree indexes. This adds two SQL-callable functions, validating B-Tree consistency to a varying degree. Check the, extensive, docs for details. The goal is to later extend the coverage of the module to further access methods, possibly including the heap. Once checks for additional access methods exist, we'll likely add some "dispatch" functions that cover multiple access methods.

# amcheck extension
comment = 'functions for verifying relation integrity'
Teach contrib/amcheck to check the unique constraint violation Add the 'checkunique' argument to bt_index_check() and bt_index_parent_check(). When the flag is specified the procedures will check the unique constraint violation for unique indexes. Only one heap entry for all equal keys in the index should be visible (including posting list entries). Report an error otherwise. pg_amcheck called with the --checkunique option will do the same check for all the indexes it checks.
