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.
