The repeat() function loops for potentially a long time without
ever checking for interrupts. This prevents, for example, a query
cancel from interrupting until the work is all done. Fix by
inserting a CHECK_FOR_INTERRUPTS() into the loop.

This is not handled uniformly throughout the code, but at least nearby

Disk-based HashAgg relies on writing to multiple tapes
concurrently. Avoid fragmentation of the tapes' blocks by
preallocating many blocks for a tape at once. No file operations are
performed during preallocation; only the block numbers are reserved.

Probably copied from nearby calls where it is necessary.  But this one
also casts away constness, so it was doubly annoying.

The previous indentation of optimizer functions was unclear; adjust the
indentation dashes so that a deeper level of indentation indicates that
the outer optimizer function calls the inner one.

The B-Tree index deduplication strategy used during CREATE INDEX and
REINDEX differs from the lazy strategy used by retail inserts.  Make
that clear by adding a new paragraph to the B-Tree implementation
section of the documentation.

In passing, do some copy-editing of nearby deduplication documentation.

When installing binaries and libraries using the MSVC installation
routines, the operation gets done after moving to the root folder, whose
location is detected by checking if "configure" exists two times in a
row.  So, calling the installation script from src/tools/msvc/ with an
extra "configure" file four levels up the root path of the code tree
causes the execution to go further up, leading to a failure in finding
the builds.  This commit fixes the issue by moving to the root folder of
the code tree only once, when necessary.

This should be plain old ColId.  Making it so makes the grammar less
complicated, and makes the compiled tables a kilobyte or so smaller
(likely because they don't have to deal with a keyword classification
that's not used anyplace else).

Commit 624686ab added an assertion that verified that _bt_search
successfully relocated the leaf page undergoing deletion.  Page deletion
cannot deal with the case where the descent stack is to the right of the
page, so this seemed critical (deletion can only handle the case where
the descent stack is to the left of the leaf/target page).  However, the
assertion went a bit too far.

Since only a buffer pin is held on the leaf page throughout the call to
_bt_search, nothing guarantees that it can't have split during this
small window.  And if does actually split, _bt_search may end up
"relocating" a page to the right of the original target leaf page.  This
scenario seems extremely unlikely, but it must still be considered.
Remove the assertion, and document how we cope in this scenario.

FETCH FIRST .. ONLY implements this correctly, but we missed to include
it for FETCH FIRST .. WITH TIES in commit 357889eb.
