Fix relative path references so that make knowns which dependencies refer to one another. Sort out builddir vs srcdir variable namings. Remove some now obsoleted make variables.

Fix VPATH builds, broken by my recent commit to speed up tuplesorting. The relevant commit is 337b6f5ecf05b21b5e997986884d097d60e4e3d0.

Split all OBJS style lines in makefiles into one-line-per-entry style. When maintaining or merging patches, one of the most common sources for conflicts are the list of objects in makefiles. Especially when the split across lines has been changed on both sides, which is somewhat common due to attempting to stay below 80 columns, those conflicts are unnecessarily laborious to resolve. By splitting, and alphabetically sorting, OBJS style lines into one object per line, conflicts should be less frequent, and easier to resolve when they still occur.

Invent qsort_interruptible(). Justin Pryzby reported that some scenarios could cause gathering of extended statistics to spend many seconds in an un-cancelable qsort() operation. To fix, invent qsort_interruptible(), which is just like qsort_arg() except that it will also do CHECK_FOR_INTERRUPTS every so often. This bloats the backend by a couple of kB, which seems like a good investment. (We considered just enabling CHECK_FOR_INTERRUPTS in the existing qsort and qsort_arg functions, but there are some callers for which that'd demonstrably be unsafe. Opt-in seems like a better way.) For now, just apply qsort_interruptible() in statistics collection. There's probably more places where it could be useful, but we can always change other call sites as we find problems. Back-patch to v14. Before that we didn't have extended stats on expressions, so that the problem was less severe. Also, this patch depends on the sort_template infrastructure introduced in v14.

Split tuplesortvariants.c from tuplesort.c This commit puts the implementation of Tuple sort variants into the separate file tuplesortvariants.c. That gives better separation of the code and serves well as the demonstration that Tuple sort variant can be defined outside of tuplesort.c.
