74a68e37d0 Free leaked result set in pg_rewind
It was not significant in practice, it was just one instance of a small
result set, but let's pacify Coverity.

c67f366fa9 Fix multiple bugs and infelicities in pg_rewind.
Bugs all spotted by Coverity, including wrong realloc() size request
and memory leaks.  Cosmetic improvements by me.

The usage of the global variable "filemap" here is still pretty awful,
but at least I got rid of the gratuitous aliasing in several routines
(which was helping to annoy Coverity, as well as being a bug risk).

61081e75c6 Add pg_rewind, for re-synchronizing a master server after failback.
Earlier versions of this tool were available (and still are) on github.

Thanks to Michael Paquier, Alvaro Herrera, Peter Eisentraut, Amit Kapila,
and Satoshi Nagayasu for review.
