pathspec: add new function to parse file
This will be used to support the new option '--pathspec-from-file' in
`git add`, `git-commit`, `git reset` etc.
Note also that we specifically handle CR/LF line endings to support
Windows better.
To simplify code, file is first parsed into `argv_array`. This allows
to avoid refactoring `parse_pathspec()`.
I considered adding `nul_term_line` to `flags` instead, but decided
that it doesn't fit there.
The new code is mostly taken from `cmd_update_index()` and
`split_mail_conv()`.
