Teach `make coccicheck` to avoid patches named "*.pending.cocci" and
handle them separately in a new `make coccicheck-pending` instead.
This means that we can separate "critical" patches from "FYI" patches.
The former target can continue causing Travis to fail its static
analysis job, while the latter can let us keep an eye on ongoing
(pending) transitions without them causing too much fallout.
Document the intended use-cases around these two targets.
As the process around the pending patches is not yet fully explored,
leave that out.

Commit 43662b23ab (format-patch: keep cover-letter diffstat wrapped in
72 columns - 2018-01-24) uncondtionally sets stat width to 72 when
generating diffstat for the cover letter, ignoring --stat from command
line. But it should only do so when stat width is still default
(i.e. stat_width == 0).
In order to fix this, we should only set stat_width if stat_width is
zero. But it will never be. Commit 071dd0ba43 (format-patch: reduce
patch diffstat width to 72 - 2018-02-01) makes sure that default stat
width will be 72 (ignoring $COLUMNS, but could still be overriden by
--stat). So all we need to do here is drop the assignment.

When we converted a `git checkout -q $onto^0` call to use
`reset_head()`, we inadvertently incurred a change from a twoway_merge
to a oneway_merge, as if we wanted a `git reset --hard` instead.
This has performance ramifications under certain, though, as the
oneway_merge needs to lstat() every single index entry whereas
twoway_merge does not.
So let's go back to the old behavior.

`--exclude` from rev-list and rev-parse fails to exclude references if
the next `--branches`, `--tags` or `--remotes` use the optional
inclusive glob because those options are implemented as particular cases
of `--glob=`, which itself requires that exclude patterns begin with
'refs/'.
But it makes sense for `--branches=glob` and friends to be aware that
exclusions patterns for them shouldn't be 'refs/<type>/' prefixed, the
same way exclude patterns for `--branches` and friends (without the
optional glob) already are.
Let's record in 'refs.c:struct ref_filter' which context the exclude
pattern is tied to, so refs.c:filter_refs() can decide if it should
ignore the prefix when trying to match.

The documentation of `--exclude=` option from rev-list and rev-parse
explicitly states that exclude patterns *should not* start with 'refs/'
when used with `--branches`, `--tags` or `--remotes`.
However, following this advice results in refereces not being excluded
if the next `--branches`, `--tags`, `--remotes` use the optional
inclusive glob.

When editing patches e.g. in `git add -e`, it is quite common that a
hunk ends up having no -/+ lines, i.e. it is now supposed to do nothing.
This use case was broken by ad6e8ed37b (apply: reject a hunk that does
not do anything, 2015-06-01) with the good intention of catching a very
real, different issue in hand-edited patches.
So let's use the `--recount` option as the tell-tale whether the user
would actually be okay with no-op hunks.
Add a test case to make sure that this use case does not regress again.

When we detect that a `merge` can be skipped because the merged commit
is already an ancestor of HEAD, we do not need to commit, therefore
writing the MERGE_HEAD file is useless.
It is actually worse than useless: a subsequent `git commit` will pick
it up and think that we want to merge that commit, still.
To avoid that, move the code that writes the MERGE_HEAD file to a
location where we already know that the `merge` cannot be skipped.

When setting
DEVELOPER = 1
DEVOPTS = extra-all
"gcc (Raspbian 6.3.0-18+rpi1+deb9u1) 6.3.0 20170516" errors out with
"comparison is always false due to limited range of data type"
"[-Werror=type-limits]"
It turns out that the function xcurl_off_t() has 2 flavours:
- It gives a warning 32 bit systems, like Linux
- It takes the signed ssize_t as a paramter, but the only caller is using
a size_t (which is typically unsigned these days)
The original motivation of this function is to make sure that sizes > 2GiB
are handled correctly. The curl documentation says:
"For any given platform/compiler curl_off_t must be typedef'ed to a 64-bit
wide signed integral data type"
On a 32 bit system "size_t" can be promoted into a 64 bit signed value
without loss of data, and therefore we may see the
"comparison is always false" warning.
On a 64 bit system it may happen, at least in theory, that size_t is > 2^63,
and then the promotion from an unsigned "size_t" into a signed "curl_off_t"
may be a problem.
One solution to suppress a possible compiler warning could be to remove
the function xcurl_off_t().
However, to be on the very safe side, we keep it and improve it:
- The len parameter is changed from ssize_t to size_t
- A temporally variable "size" is used, promoted int uintmax_t and the compared
with "maximum_signed_value_of_type(curl_off_t)".
Thanks to Junio C Hamano for this hint.

When printing variables which contain a size, today "unsigned long"
is used at many places.
In order to be able to change the type from "unsigned long" into size_t
some day in the future, we need to have a way to print 64 bit variables
on a system that has "unsigned long" defined to be 32 bit, like Win64.
Upcast all those variables into uintmax_t before they are printed.
This is to prepare for a bigger change, when "unsigned long"
will be converted into size_t for variables which may be > 4Gib.
