[BlueZ v3 0/6] Add helper for "cleanup" variable attribute

[Bastien Nocera <hadess@hadess.net>]

As discussed in:
https://lore.kernel.org/linux-bluetooth/ed949f2550f79a4bef19bd482bf8b069ad5b7e0c.camel@hadess.net/

Implement a cleanup helper.

The MIN/MAX fix is here because it touches the same hunk in src/main.c
as the other patches. Feel free to pick it up straight away while the
rest is discussed.

Changes since v2:
- Add macros to declare cleanup for specific types
- Add file descriptor cleanup
- Add "steal" helpers for fd and pointers
- Add unit tests

Changes since v1:
- Fixed checkpatch warnings

Bastien Nocera (6):
  all: Remove more unneeded MIN/MAX macro definition
  shared/util: Add helper for "cleanup" variable attribute
  doc: Recommend using _cleanup_ and friends
  main: Use _cleanup_() to simplify configuration parsing
  client: Use _cleanup_fd_ to simplify urandom access
  btattach: Use _cleanup_fd_ to simplify error paths
