Update buffile.h/.c comments for removal of non-temp option.
Commit 11e264517 removed BufFile's isTemp flag, thereby eliminating
the possibility of resurrecting BufFileCreate(). But it left that
function in place, as well as a bunch of comments describing how things
worked for the non-temp-file case. At best, that's now a source of
confusion. So remove the long-since-commented-out function and change
relevant comments.
I (tgl) wanted to rename BufFileCreateTemp() to BufFileCreate(), but
that seems not to be the consensus position, so leave it as-is.
In passing, fix commit f0828b2fc's failure to update BufFileSeek's
comment to match the change of its argument type from long to off_t.
(I think that might actually have been intentional at the time, but
now that 64-bit off_t is nearly universal, it looks anachronistic.)
