Fix sparse warnings Fix warnings from 'make check'. - These files don't include 'builtin.h' causing sparse to complain that cmd_* isn't declared: builtin/clone.c:364, builtin/fetch-pack.c:797, builtin/fmt-merge-msg.c:34, builtin/hash-object.c:78, builtin/merge-index.c:69, builtin/merge-recursive.c:22 builtin/merge-tree.c:341, builtin/mktag.c:156, builtin/notes.c:426 builtin/notes.c:822, builtin/pack-redundant.c:596, builtin/pack-refs.c:10, builtin/patch-id.c:60, builtin/patch-id.c:149, builtin/remote.c:1512, builtin/remote-ext.c:240, builtin/remote-fd.c:53, builtin/reset.c:236, builtin/send-pack.c:384, builtin/unpack-file.c:25, builtin/var.c:75 - These files have symbols which should be marked static since they're only file scope: submodule.c:12, diff.c:631, replace_object.c:92, submodule.c:13, submodule.c:14, trace.c:78, transport.c:195, transport-helper.c:79, unpack-trees.c:19, url.c:3, url.c:18, url.c:104, url.c:117, url.c:123, url.c:129, url.c:136, thread-utils.c:21, thread-utils.c:48 - These files redeclare symbols to be different types: builtin/index-pack.c:210, parse-options.c:564, parse-options.c:571, usage.c:49, usage.c:58, usage.c:63, usage.c:72 - These files use a literal integer 0 when they really should use a NULL pointer: daemon.c:663, fast-import.c:2942, imap-send.c:1072, notes-merge.c:362 While we're in the area, clean up some unused #includes in builtin files (mostly exec_cmd.h).

#include "builtin.h"
Honor core.precomposeUnicode in more places On Mac's HFS where git sets core.precomposeUnicode to true automatically by git init/clone, when a user creates a simple unicode refname (in NFC format) such as españa: $ git branch españa different commands would display the branch name differently. For example, git branch, git log --decorate, and git fast-export all used 65 73 70 61 c3 b1 61 (or "espa\xc3\xb1a") (NFC form) while show-ref would use 65 73 70 61 6e cc 83 61 (or "espan\xcc\x83a") (NFD form). A stress test for git filter-repo was tripped up by this inconsistency, though digging in I found that the problems could compound; for example, if the user ran $ git pack-refs --all and then tried to check out the branch, they would be met with: $ git checkout españa error: pathspec 'españa' did not match any file(s) known to git $ git checkout españa -- fatal: invalid reference: españa $ git branch españa * master Note that the user could run the `git branch` command first and copy and paste the `españa` portion of the output and still see the same two errors. Also, if the user added --no-prune to the pack-refs command, then they would see three branches: master, españa, and españa (those last two are NFC vs. NFD forms, even if they render the same). Further, if the user had the `españa` branch checked out before running `git pack-refs --all`, the user would be greeted with (note that I'm trimming trailing output with an ellipsis): $ git rev-parse HEAD fatal: ambiguous argument 'HEAD': unknown revision or path... $ git status On branch españa No commits yet... Or worse, if the user didn't check this stuff first, running `git commit` will create a new commit with all changes of all of history being squashed into it. In addition to pack-refs, one could also get into this state with upload-pack or anything that calls either pack-refs or upload-pack (e.g. gc or clone). Add code in a few places (pack-refs, show-ref, upload-pack) to check and honor the setting of core.precomposeUnicode to avoid these bugs.
