  git-contacts: do not fail parsing of good diffs

"git config" learned to read from the standard input when "-" is
given as the value to its "--file" parameter (attempting an
operation to update the configuration in the standard input of
course is rejected).

* ks/config-file-stdin:
  config: teach "git config --file -" to read from the standard input
  config: change git_config_with_options() interface

  utf8: fix iconv error detection
  notes-utils: handle boolean notes.rewritemode correctly

Uses of curl's "multi" interface and "easy" interface do not mix
well when we attempt to reuse outgoing connections.  Teach the RPC
over http code, used in the smart HTTP transport, not to use the
"easy" interface.

* jk/http-no-curl-easy:
  http: never use curl_easy_perform

* ss/completion-rec-sub-fetch-push:
  completion: teach --recurse-submodules to fetch, pull and push

Trailing whitespaces in .gitignore files, unless they are quoted for
fnmatch(3), e.g. "path\ ", are warned and ignored.

Strictly speaking, this is a backward incompatible change, but very
unlikely to bite any sane user and adjusting should be obvious and
easy.

* nd/gitignore-trailing-whitespace:
  t0008: skip trailing space test on Windows
  dir: ignore trailing spaces in exclude patterns
  dir: warn about trailing spaces in exclude patterns

"git check-attr" when (trying to) work on a repository with a
working tree did not work well when the working tree was specified
via --work-tree (and obviously with --git-dir).

The command also works in a bare repository but it reads from the
(possibly stale, irrelevant and/or nonexistent) index, which may
need to be fixed to read from HEAD, but that is a completely
separate issue.  As a related tangent to this separate issue, we
may want to also fix "check-ignore", which refuses to work in a
bare repository, to also operate in a bare one.

* jc/check-attr-honor-working-tree:
  check-attr: move to the top of working tree when in non-bare repository
  t0003: do not chdir the whole test process

The Windows API does not preserve file names with trailing spaces (and
dots), but rather strips them. Our tools (MSYS bash, git) base the POSIX
emulation on the Windows API. As a consequence, it is impossible for bash
on Windows to allocate a file whose name has trailing spaces, and for git
to stat such a file. Both operate on a file whose name has the spaces
stripped. Skip the test that needs such a file name.

Note that we do not use (another incarnation of) prerequisite FUNNYNAMES.
The reason is that FUNNYNAMES is intended to represent a property of the
file system. But the inability to have trailing spaces in a file name is
a property of the Windows API. The file system (NTFS) does not have this
limitation.

prefixcmp/suffixcmp are gone.

Remove a confusing and deprecated "-q" option from "git diff-files";
"git diff-files --diff-filter=d" can be used instead.

"core.statinfo" configuration variable, which was a never-advertised
synonym to "core.checkstat", has been removed.

"git add <pathspec>" is the same as "git add -A <pathspec>" now,
i.e. it does not ignore removals from the directory specified.

"git add -u" and "git add -A" without any pathspec is a tree-wide
operation now, even when they are run in a subdirectory of the
working tree.

Finally update the "git push" default behaviour to "simple".

Teach "make test" to run networking tests when possible by default.

Teach combine-diff to honour the path-output-order imposed by
diffcore-order, and optimize how matching paths are found in
the N-way diffs made with parents.

  tests: add checking that combine-diff emits only correct paths
  combine-diff: simplify intersect_paths() further
  combine-diff: combine_diff_path.len is not needed anymore
  combine-diff: optimize combine_diff_path sets intersection
  diff test: add tests for combine-diff with orderfile

Attempting to deepen a shallow repository by fetching over smart
HTTP transport failed in the protocol exchange, when no-done
extension was used.  The fetching side waited for the list of
shallow boundary commits after the sending end stopped talking to
it.

  t5537: move http tests out to t5539
  fetch-pack: fix deepen shallow over smart http with no-done cap

Borrow the bitmap index into packfiles from JGit to speed up

All subcommands that take pathspecs mishandled an in-tree symbolic
link when given it as a full path from the root (which arguably is
a sick way to use pathspecs).  "git ls-files -s $(pwd)/RelNotes" in
our tree is an easy reproduction recipe.
