parse-options.h: add new options `--pathspec-from-file`, `--pathspec-file-nul`
Support for various porcelain commands will arrive via additional
patches.
`--pathspec-from-file` solves the problem of commandline length limit
for UIs built on top of git. Plumbing commands are not always a good
fit, for two major reasons:
1) Some UIs show executed commands to user. In this case, porcelain
commands are expected. One reason for that is letting user learn git
commands by clicking UI buttons. The other reason is letting user
study the history of commands in case of any unexpected results. Both
of these will lose most of their value if UI uses combinations of
arcane plumbing commands.
2) Some UIs have started and grown with porcelain commands. Replacing
existing logic with plumbing commands could be cumbersome and prone
to various new problems.
`--pathspec-from-file` will behave very close to pathspec passed in
commandline args, so that switching from one to another is simple.
`--pathspec-from-file` will read either a specified file or `stdin`
(when file is exactly "-"). Reading from file is a good way to avoid
competing for `stdin`, and also gives some extra flexibility.
`--pathspec-file-nul` switch mirrors `-z` already used in various
places. Some porcelain commands, such as `git commit`, already use
`-z`, therefore it needed a new unambiguous name.
New options do not have shorthands to avoid shorthand conflicts. It is
not expected that they will be typed in console.
