  apply --whitespace=fix: detect new blank lines at eof correctly
  apply --whitespace=fix: fix handling of blank lines at the eof

The earlier logic tried to colour any and all blank lines that were added
beyond the last blank line in the original, but this was very wrong.  If
you added 96 blank lines, a non-blank line, and then 3 blank lines at the
end, only the last 3 lines should trigger the error, not the earlier 96
blank lines.

We need to also make sure that the lines are after the last non-blank line
in the postimage as well before deciding to paint them.

Make http.c::fetch_pack_index() no longer check for the remote pack
with a HEAD request before fetching the corresponding pack index file.

Not only does sending a HEAD request before we do a GET incur a
performance penalty, it does not offer any significant error-
prevention advantages (pack fetching in the *_http_pack_request()
methods is capable of handling any errors on its own).

This addresses an issue raised elsewhere:

People who configured trailing-space depended on it to catch both extra
white space at the end of line, and extra blank lines at the end of file.
Earlier attempt to introduce only blank-at-eof gave them an escape hatch
to keep the old behaviour, but it is a regression until they explicitly
specify the new error class.

This introduces a blank-at-eol that only catches extra white space at the
end of line, and makes the traditional trailing-space a convenient synonym
to catch both blank-at-eol and blank-at-eof.  This way, people who used
trailing-space continue to catch both classes of errors.

Since the coloring logic processed the patch output one line at a time, we
couldn't easily color code the new blank lines at the end of file.

Reuse the adds_blank_at_eof() function to find where the runs of such
blank lines start, keep track of the line number in the preimage while
processing the patch output one line at a time, and paint the new blank
lines that appear after that line to implement this.

The "diff --check" logic used to share the same issue as the one fixed for
"git apply" earlier in this series, in that a patch that adds new blank
lines at end could appear as

    @@ -l,5 +m,7 @@$
    _context$
    _context$
    -deleted$
    +$
    +$
    +$
    _$

where _ stands for SP and $ shows a end-of-line.  Instead of looking at
each line in the patch in the callback, simply count the blank lines from
the end in two versions, and notice the presence of new ones.

The "diff --check" code used to conflate trailing-space whitespace error
class with this, but now we have a proper separate error class, we should
check it under blank-at-eof, not trailing-space.

The whitespace error is not about _having_ blank lines at end, but about
adding _new_ blank lines.  To keep the message consistent with what is
given by "git apply", call whitespace_error_string() to generate it,
instead of using a hardcoded custom message.

"git apply" strips new blank lines at EOF under --whitespace=fix option,
but neigher --whitespace=warn nor --whitespace=error paid any attention to
these errors.

Introduce a new whitespace error class, blank-at-eof, to make the
whitespace error handling more consistent.

The patch adds a new "linenr" field to the struct fragment in order to
record which line the hunk started in the input file, but this is needed
solely for reporting purposes.  The detection of this class of whitespace
errors cannot be done while parsing a patch like we do for all the other
classes of whitespace errors.  It instead has to wait until we find where
to apply the hunk, but at that point, we do not have an access to the
original line number in the input file anymore, hence the new field.

Depending on your point of view, this may be a bugfix that makes warn and
error in line with fix.  Or you could call it a new feature.  The line
between them is somewhat fuzzy in this case.

Strictly speaking, triggering more errors than before is a change in
behaviour that is not backward compatible, even though the reason for the
change is because the code was not checking for an error that it should
have.  People who do not want added blank lines at EOF to trigger an error
can disable the new error class.

This splits the logic to record the presence of whitespace errors out of
the check_whitespace() function, which checks and then records.  The new
function, record_ws_error(), can be used by the blank-at-eof check that
does not use ws_check() logic to report its findings in the same output
format.

The command tries to strip blank lines at the end of the file added by a
patch.  It is done by first detecting if a hunk in patch has additional
blank lines at the end of itself, and if so checking if such a hunk
applies at the end of file.  This patch addresses a bug in the logic to
implement the former (the previous one addressed a bug in the latter).

If the original ends with blank lines, often the patch hunk ends like
this:

    @@ -l,5 +m,7 @@$
    _context$
    _context$
    -deleted$
    +$
    +$
    +$
    _$
    _$

where _ stands for SP and $ shows a end-of-line.  This example patch adds
three trailing blank lines, but the code fails to notice it, because it
only pays attention to added blank lines at the very end of the hunk.  In
this example, the three added blank lines do not appear textually at the
end in the patch, even though you can see that they are indeed added at
the end, if you rearrange the diff like this:

    @@ -l,5 +m,7 @@$
    _context$
    _context$
    -deleted$
    _$
    _$
    +$
    +$
    +$

The fix is not to reset the number of (candidate) added blank lines at the
end when the loop sees a context line that is empty.

b94f2eda (builtin-apply.c: make it more line oriented, 2008-01-26) broke
the logic used to detect if a hunk adds blank lines at the end of the
file.  With the new code after that commit:

 - img holds the contents of the file that the hunk is being applied to;

 - preimage has the lines the hunk expects to be in img; and

 - postimage has the lines the hunk wants to update the part in img that
   corresponds to preimage with.

and we need to compare if the last line of preimage (not postimage)
matches the last line of img to see if the hunk applies at the end of the
file.

The current code just leaves the transport in whatever state
it was in after performing the fetch.  For a non-empty clone
over the git protocol, the transport code already
disconnects at the end of the fetch.

But for an empty clone, we leave the connection hanging, and
eventually close the socket when clone exits. This causes
the remote upload-pack to complain "the remote end hung up
unexpectedly". While this message is harmless to the clone
itself, it is unnecessarily scary for a user to see and may
pollute git-daemon logs.

This patch just explicitly calls disconnect after we are
done with the remote end, which sends a flush packet to
upload-pack and cleanly disconnects, avoiding the error
message.

Other transports are unaffected or slightly improved:

 - for a non-empty repo over the git protocol, the second
   disconnect is a no-op (since we are no longer connected)

 - for "walker" transports (like HTTP or FTP), we actually
   free some used memory (which previously just sat until
   the clone process exits)

 - for "rsync", disconnect is always a no-op anyway
