3cbc6ed3ee commit-graph: rename commit_compare to oid_compare
The helper function commit_compare() actually compares object_id
structs, not commits. A future change to commit-graph.c will need
to sort commit structs, so rename this function in advance.

d4f4d60f6d commit-graph: prepare for commit-graph chains
To prepare for a chain of commit-graph files, augment the
commit_graph struct to point to a base commit_graph. As we load
commits from the graph, we may actually want to read from a base
file according to the graph position.

The "graph position" of a commit is given by concatenating the
lexicographic commit orders from each of the commit-graph files in
the chain. This means that we must distinguish two values:

 * lexicographic index : the position within the lexicographic
   order in a single commit-graph file.

 * graph position: the position within the concatenated order
   of multiple commit-graph files

Given the lexicographic index of a commit in a graph, we can
compute the graph position by adding the number of commits in
the lower-level graphs. To find the lexicographic index of
a commit, we subtract the number of commits in lower-level graphs.

While here, change insert_parent_or_die() to take a uint32_t
position, as that is the type used by its only caller and that
makes more sense with the limits in the commit-graph format.

63b50c8ffe stash: fix show referencing stash index
In the conversion of 'stash show' to C in dc7bd382b1 ("stash: convert
show to builtin", 2019-02-25), 'git stash show <n>', where n is the
index of a stash got broken, if n is not a file or a valid revision by
itself.

'stash show' accepts any flag 'git diff' accepts for changing the
output format.  Internally we use 'setup_revisions()' to parse these
command line flags.  Currently we pass the whole argv through to
'setup_revisions()', which includes the stash index.

As the stash index is not a valid revision or a file in the working
tree in most cases however, this 'setup_revisions()' call (and thus
the whole command) ends up failing if we use this form of 'git stash
show'.

Instead of passing the whole argv to 'setup_revisions()', only pass
the flags (and the command name) through, while excluding the stash
reference.  The stash reference is parsed (and validated) in
'get_stash_info()' already.

This separate parsing also means that we currently do produce the
correct output if the command succeeds.

28438e84e0 ref-filter: sort detached HEAD lines firstly
Before this patch, "git branch" would put "(HEAD detached...)" and "(no
branch, rebasing...)" lines before all the other branches *in most
cases* except for when using Chinese-language messages. zh_CN generally
uses a full-width "(" symbol (codepoint FF08) to match the full-width
proportions of Chinese characters, and the translated strings we had did
use them. This meant that the detached HEAD line would appear after all
local refs and even after the remote refs if there were any.

AFAIK, it is sometimes not jarring to see the half-width parenthesis in
"full-width" text as in the CJK languages, for instance when there are
no characters preceding or following the parenthesized text fragment. By
removing the parenthesis from the localizable text, we can share strings
with wt-status.c and remove a cautionary comment to translators.

Remove the ( from the localizable portion of messages so the sorting
happens properly regardless of locale.

7a06fb038c wt-status.h: drop stdio.h include
We started including stdio.h to pick up the declaration of "FILE" in
f26a001226 (Enable wt-status output to a given FILE pointer.,
2007-09-17). But there's no need, since headers can assume that
git-compat-util.h has been included, which covers stdio.

This should just be redundant, and not hurting anything (like pulling in
includes out of order) because C files are supposed to always include
git-compat-util.h first. But it's worth cleaning up to model good
behavior.

96728b2236 verify-tag: drop signal.h include
There's no reason verify-tag.c needs to include signal.h. It's already
in git-compat-util.h, which we properly include as the first header.
And there doesn't seem to be a particular reason for this include; it's
just an artifact from the file creation in 2ae68fcb78 (Make verify-tag a
builtin., 2007-07-27).

Likewise verify-commit.c has the same issue, probably because it was
created using verify-tag as a template in d07b00b7f3 (verify-commit:
scriptable commit signature verification, 2014-06-23).

These includes are probably just redundant, and not hurting anything by
circumventing the order that git-compat-util.h tries to impose, since
we'll always have loaded git-compat-util by the time we get to these. So
this is just a cleanup, and shouldn't fix or break any platforms.

729a9b558b wrapper: avoid undefined behaviour in macOS
0620b39b3b ("compat: add a mkstemps() compatibility function", 2009-05-31)
included a function based on code from libiberty which would result in
undefined behaviour in platforms where timeval's tv_usec is a 32-bit signed
type as shown by:

wrapper.c:505:31: runtime error: left shift of 594546 by 16 places cannot be represented in type '__darwin_suseconds_t' (aka 'int')

interestingly the version of this code from gcc never had this bug and the
code had a cast that would had prevented the issue (at least in 64-bit
platforms) but was misapplied.

change the cast to uint64_t so it also works in 32-bit platforms.

29c83fc23f interpret-trailers: load default config
The interpret-trailers program does not do the usual loading of config
via git_default_config(), and thus does not respect many of the usual
options. In particular, we will not load core.commentChar, even though
the underlying trailer code uses its value.

This can be seen in the accompanying test, where setting
core.commentChar to anything besides "#" results in a failure to treat
the comments correctly.

177fbab747 coccinelle: use COPY_ARRAY for copying arrays
The current semantic patch for COPY_ARRAY transforms memcpy(3) calls on
pointers, but Coccinelle distinguishes them from arrays.  It already
contains three rules to handle the options for sizeof (i.e. source,
destination and type), and handling arrays as source and destination
would require four times as many rules if we enumerated all cases.

We also don't handle array subscripts, and supporting that would
increase the number of rules by another factor of four.  (An isomorphism
telling Coccinelle that "sizeof x[...]" is equivalent to "sizeof *x"
would be nice..)

Support arrays and array subscripts, but keep the number of rules down
by adding normalization steps: First turn array subscripts into
derefences, then determine the types of expressions used with sizeof and
replace them with these types, and then convert the different possible
combinations of arrays and pointers with memcpy(3) to COPY_ARRAY.

As long as hashmap can store and retrieve values, and that it performs
