[systemd-devel] various cleanups

[Simon Peeters]

Hello,

I have tried to do some cleanups in src/shared 

The "CACHED_METHOD" one might be going a bit to far,
so feel free to drop it if you don't like it.

[PATCH 1/5] shared: procfs_file_alloca: handle pid==0
[PATCH 2/5] util: CACHED_METHOD macro
[PATCH 3/5] shared: util.c: unify split and split_quoted
[PATCH 4/5] util.c: use read_one_line_file where possible
[PATCH 5/5] strv: multiple cleanups
