Implement %(if), %(then) and %(else) atoms. Used as
%(if)...%(then)...%(end) or %(if)...%(then)...%(else)...%(end). If the
format string between %(if) and %(then) expands to an empty string, or
to only whitespaces, then the whole %(if)...%(end) expands to the string
following %(then). Otherwise, it expands to the string following
%(else), if any. Nesting of this construct is possible.
This is in preparation for porting over `git branch -l` to use
ref-filter APIs for printing.
Add Documentation and tests regarding the same.

Ensure that each 'atom_value' has a reference to its corresponding
'used_atom'. This let's us use values within 'used_atom' in the
'handler' function.
Hence we can get the %(align) atom's parameters directly from the
'used_atom' therefore removing the necessity of passing %(align) atom's
parameters to 'atom_value'.
This also acts as a preparatory patch for the upcoming patch where we
introduce %(if:equals=) and %(if:notequals=).

Implement %(if:equals=<string>) wherein the if condition is only
satisfied if the value obtained between the %(if:...) and %(then) atom
is the same as the given '<string>'.
Similarly, implement (if:notequals=<string>) wherein the if condition
is only satisfied if the value obtained between the %(if:...) and
%(then) atom is differnt from the given '<string>'.
This is done by introducing 'if_atom_parser()' which parses the given
%(if) atom and then stores the data in used_atom which is later passed
on to the used_atom of the %(then) atom, so that it can do the required
comparisons.
Add tests and Documentation for the same.

Add support for %(objectname:short=<length>) which would print the
abbreviated unique objectname of given length. When no length is
specified, the length is 'DEFAULT_ABBREV'. The minimum length is
'MINIMUM_ABBREV'. The length may be exceeded to ensure that the provided
object name is unique.
Add tests and documentation for the same.

Move the implementation of get_head_description() from branch.c to
ref-filter. This gives a description of the HEAD ref if called. This
is used as the refname for the HEAD ref whenever the
FILTER_REFS_DETACHED_HEAD option is used. Make it public because we
need it to calculate the length of the HEAD refs description in
branch.c:calc_maxwidth() when we port branch.c to use ref-filter
APIs.

To allow column display, we will need to first render the output in a
string list to allow print_columns() to compute the proper size of
each column before starting the actual output. Introduce the function
format_ref_array_item() that does the formatting of a ref_array_item
to an strbuf.
show_ref_array_item() is kept as a convenience wrapper around it which
obtains the strbuf and prints it the standard output.

Borrowing from branch.c's implementation print "[gone]" whenever an
unknown upstream ref is encountered instead of just ignoring it.
This makes sure that when branch.c is ported over to using ref-filter
APIs for printing, this feature is not lost.
Make changes to t/t6300-for-each-ref.sh and
Documentation/git-for-each-ref.txt to reflect this change.

Add support for %(upstream:track,nobracket) which will print the
tracking information without the brackets (i.e. "ahead N, behind M").
This is needed when we port branch.c to use ref-filter's printing APIs.
Add test and documentation for the same.

The "%(symref)" atom doesn't work when used with the ':short' modifier
because we strictly match only 'symref' for setting the 'need_symref'
indicator. Fix this by using comparing with valid_atom rather than used_atom.
Add tests for %(symref) and %(symref:short) while we're here.

Since there are multiple atoms which print refs ('%(refname)',
'%(symref)', '%(push)', '%upstream'), it makes sense to have a common
ground for parsing them. This would allow us to share implementations of
the atom modifiers between these atoms.
Introduce refname_atom_parser_internal() to act as a common parsing
function for ref printing atoms. This would eventually be used to
introduce refname_atom_parser() and symref_atom_parser() and also be
internally used in remote_ref_atom_parser().

Using refname_atom_parser_internal(), introduce symref_atom_parser() and
refname_atom_parser() which will parse the atoms %(symref) and
%(refname) respectively. Store the parsed information into the
'used_atom' structure based on the modifiers used along with the atoms.
Now the '%(symref)' atom supports the ':strip' atom modifier. Update the
Documentation and tests to reflect this.

Use the recently introduced refname_atom_parser_internal() within
remote_ref_atom_parser(), this provides a common base for all the ref
printing atoms, allowing %(upstream) and %(push) to also use the
':strip' option.
The atoms '%(push)' and '%(upstream)' will retain the ':track' and
':trackshort' atom modifiers to themselves as they have no meaning in
context to the '%(refname)' and '%(symref)' atoms.
Update the documentation and tests to reflect the same.

Add the options `:dir` and `:base` to all ref printing ('%(refname)',
'%(symref)', '%(push)' and '%(upstream)') atoms. The `:dir` option gives
the directory (the part after $GIT_DIR/) of the ref without the
refname. The `:base` option gives the base directory of the given
ref (i.e. the directory following $GIT_DIR/refs/).
Add tests and documentation for the same.

Introduce setup_ref_filter_porcelain_msg() so that the messages used in
the atom %(upstream:track) can be translated if needed. This is needed
as we port branch.c to use ref-filter's printing API's.

Call ref-filter's setup_ref_filter_porcelain_msg() to enable
translated messages for the %(upstream:tack) atom. Although branch.c
doesn't currently use ref-filter's printing API's, this will ensure
that when it does in the future patches, we do not need to worry about
translation.

Port branch.c to use ref-filter APIs for printing. This clears out
most of the code used in branch.c for printing and replaces them with
calls made to the ref-filter library.
Introduce build_format() which gets the format required for printing
of refs. Make amendments to print_ref_list() to reflect these changes.
Change calc_maxwidth() to also account for the length of HEAD ref, by
calling ref-filter:get_head_discription().
Also change the test in t6040 to reflect the changes.
Before this patch, all cross-prefix symrefs weren't shortened. Since
we're using ref-filter APIs, we shorten all symrefs by default. We also
allow the user to change the format if needed with the introduction of
the '--format' option in the next patch.

Implement the '--format' option provided by 'ref-filter'. This lets the
user list branches as per desired format similar to the implementation
in 'git for-each-ref'.
Add tests and documentation for the same.

Presumably w is computed here to be used later for some kind of
alignment? It is curious why we can assume that head_desc does not
need utf8_strwidth() here.

Seems to be a bug, `get_head_description()` is susceptible to be changed
due to translation and hence `utf8_strwidth()` would be a better candidate here
rather than `strlen()`.
Thanks.
