Convert most uses of OPT_BOOLEAN/OPTION_BOOLEAN that can use
OPT_BOOL/OPTION_BOOLEAN which have much saner semantics, and turn
remaining ones into OPT_SET_INT, OPT_COUNTUP, etc. as necessary.
* sb/parseopt-boolean-removal:
revert: use the OPT_CMDMODE for parsing, reducing code
checkout-index: fix negations of even numbers of -n
config parsing options: allow one flag multiple times
hash-object: replace stdin parsing OPT_BOOLEAN by OPT_COUNTUP
branch, commit, name-rev: ease up boolean conditions
checkout: remove superfluous local variable
log, format-patch: parsing uses OPT__QUIET
Replace deprecated OPT_BOOLEAN by OPT_BOOL
Remove deprecated OPTION_BOOLEAN for parsing arguments

"git check-ignore -z" applied the NUL termination to both its input
(with --stdin) and its output, but "git check-attr -z" ignored the
option on the output side.
This is potentially a backward incompatible fix. Let's see if
anybody screams before deciding if we want to do anything to help
existing users (there may be none).
* jc/check-x-z:
check-attr -z: a single -z should apply to both input and output
check-ignore -z: a single -z should apply to both input and output
check-attr: the name of the character is NUL, not NULL
check-ignore: the name of the character is NUL, not NULL

This task emerged from b04ba2bb (parse-options: deprecate OPT_BOOLEAN,
2011-09-27). All occurrences of the respective variables have
been reviewed and none of them relied on the counting up mechanism,
but all of them were using the variable as a true boolean.
This patch does not change semantics of any command intentionally.

Unless a command has separate --nul-terminated-{input,output}
options, the --nul-terminated-records (-z) option should apply
to both input and output for consistency. The caller knows that its
input paths may need to be protected for LF, and the program shows
these problematic paths to its output.
The code already did the right thing. Only the help text needs
fixing.

Enhance "check-ignore" (1.8.2 update) to work more like "check-attr"
over bidi-pipes.
* as/check-ignore:
t0008: use named pipe (FIFO) to test check-ignore streaming
Documentation: add caveats about I/O buffering for check-{attr,ignore}
check-ignore: allow incremental streaming of queries via --stdin
check-ignore: move setup into cmd_check_ignore()
check-ignore: add -n / --non-matching option
t0008: remove duplicated test fixture data

'git-status --ignored' still scans the work tree twice to collect
untracked and ignored files, respectively.
fill_directory / read_directory already supports collecting untracked and
ignored files in a single directory scan. However, the DIR_COLLECT_IGNORED
flag to enable this has some git-add specific side-effects (e.g. it
doesn't recurse into ignored directories, so listing ignored files with
--untracked=all doesn't work).
The DIR_SHOW_IGNORED flag doesn't list untracked files and returns ignored
files in dir_struct.entries[] (instead of dir_struct.ignored[] as
DIR_COLLECT_IGNORED). DIR_SHOW_IGNORED is used all throughout git.
We don't want to break the existing API, so lets introduce a new flag
DIR_SHOW_IGNORED_TOO that lists untracked as well as ignored files similar
to DIR_COLLECT_FILES, but will recurse into sub-directories based on the
other flags as DIR_SHOW_IGNORED does.
In dir.c::read_directory_recursive, add ignored files to either
dir_struct.entries[] or dir_struct.ignored[] based on the flags. Also move
the DIR_COLLECT_IGNORED case here so that filling result lists is in a
common place.
In wt-status.c::wt_status_collect_untracked, use the new flag and read
results from dir_struct.ignored[]. Remove the extra fill_directory call.
builtin/check-ignore.c doesn't call fill_directory, setting the git-add
specific DIR_COLLECT_IGNORED flag has no effect here. Remove for clarity.
Update API documentation to reflect the changes.
Performance: with this patch, 'git-status --ignored' is typically as fast
as 'git-status'.

Some callers, such as the git-annex web assistant, find it useful to
invoke git check-ignore as a persistent background process, which can
then have queries fed to its STDIN at any point, and the corresponding
response consumed from its STDOUT. For this we need to invoke
check_ignore() once per line of standard input, and flush standard
output after each result.
The above use case suggests that empty STDIN is actually a reasonable
scenario (e.g. when the caller doesn't know in advance whether any
queries need to be fed to the background process until after it's
already started), so we make the minor behavioural change that "no
pathspec given." is no longer emitted in when STDIN is empty.
Even though check_ignore() could now be changed to operate on a single
pathspec, we keep it operating on an array of pathspecs since that is
a more convenient way of consuming the existing pathspec API.

Initialisation of the dir_struct and path_exclude_check structs was
previously done within check_ignore(). This was acceptable since
check_ignore() was only called once per check-ignore invocation;
however the next commit will convert it into an inner loop which is
called once per line of STDIN when --stdin is given. Therefore moving
the initialisation code out into cmd_check_ignore() ensures that
initialisation is still only performed once per check-ignore
invocation, and consequently that the output is identical whether
pathspecs are provided as CLI arguments or via STDIN.

If `-n` or `--non-matching` are specified, non-matching pathnames will
also be output, in which case all fields in each output record except
for <pathname> will be empty. This can be useful when running
check-ignore as a background process, so that files can be
incrementally streamed to STDIN, and for each of these files, STDOUT
will indicate whether that file matched a pattern or not. (Without
this option, it would be impossible to tell whether the absence of
output for a given file meant that it didn't match any pattern, or
that the result simply hadn't been flushed to STDOUT yet.)

Usually we do not pass an empty string to the function hash_name()
because we almost always ask for hash values for a path that is a
candidate to be added to the index. However, check-ignore (and most
likely check-attr, but I didn't check) apparently has a callchain
to ask the hash value for an empty path when it was given a "." from
the top-level directory to ask "Is the path . excluded by default?"
Make sure that hash_name() does not overrun the end of the given
pathname even when it is empty.
Remove a sweep-the-issue-under-the-rug conditional in check-ignore
that avoided to pass an empty string to the callchain while at it.
It is a valid question to ask for check-ignore if the top-level is
set to be ignored by default, even though the answer is most likely
no, if only because there is currently no way to specify such an
entry in the .gitignore file. But it is an unusual thing to ask and
it is not worth optimizing for it by special casing at the top level
of the call chain.

This works in a similar manner to git-check-attr.
Thanks to Jeff King and Junio C Hamano for the idea:
