[PATCH v1 0/3] Make erofs-utils more library friendly

[Kelvin Zhang]

EROFS-utils contains several usage of global variables, namely

1. int erofs_devfd, stores the file descriptor to open'ed block devices.
This is referened in many places.
2. struct erofs_sb_info sbi; Stores parsed super block.

These global variables make embedding erofs library diffcult. To make
library usage easier, a series of 3 patches are drafted to refactor away
the global variables. Each patch has been built and tested by calling
mkfs.erofs and ensure the same output is generated.

Kelvin Zhang (3):
  Make erofs_devfd a parameter for most functions
  Mark certain callback function pointers as const
  Make super block info struct a paramater instead of globals
