[PATCH v6 0/6] Stream fd to clean filter; GIT_MMAP_LIMIT, GIT_ALLOC_LIMIT with git_env_ulong()

Changes since v5:

 - Introduce and use git_env_ulong().
 - Change copy_fd() to not close input fd, which simplified changes to convert.
 - More detailed explanation why filter must be marked "required" in commit
   message of 6/6.
 - Style fixes.

Steffen Prohaska (6):
  convert: drop arguments other than 'path' from would_convert_to_git()
  Add git_env_ulong() to parse environment variable
  Change GIT_ALLOC_LIMIT check to use git_env_ulong()
  Introduce GIT_MMAP_LIMIT to allow testing expected mmap size
  Change copy_fd() to not close input fd
  convert: stream from fd to required clean filter to reduce used
    address space
