Remove some includes from all.h
Also removes duplicates from other headers
All used std* imports are included once in all.h for easy use
- getopt: Only used in main.c and inject_randr1.5.c
- glob: Not used in i3, only in i3bar & libi3
- inttypes: Only used in util.c
- locale: A bit specific for all.h
- math: Slow according to #4022
- unistd: I feel it's good to explicitly include per file that needs it
- yajl: Specific to yajl_utils.h and ipc.h
Related to #4022
